EEV: There is no doubt extreme and conflicting reports on the Boston event. We expect it should be very easy to track where all these alleged weapons came from. In addition, police footage from the car camera’s should be able to easily validate the story.

• The Boston  bombers were reportedly planning more attacks across the city
• However, the  released of the photographs of the suspects ‘forced them out of their  hideout’
• Footage released  on Saturday shows Dzhokhar Tsranaev  laying flat under a tarp in a boat. Police used a robot  to pull the tarp off the boat
• Police  tracked him with thermal imaging cameras and engaged him in a furious exchange  of gun-fire that began shortly after 7pm
• Stand-off  continued until 8:45pm when Tsarnaev surrendered
• Dzhokhar has been  hospitalized at the Beth  Israel Deaconess Medical Center. He is ‘intubated and sedated’ and cannot yet  speak
• Tamerlan Tsarnaev  had injuries from head to toe and all limbs intact when he arrived at the  hospital. He died early on Friday

The Boston bombers were planning more attacks  across the city and were already building the bombs to do this says the city’s  police commissioner Ed Davis.

Davis says it’s his belief that 19-year-old  Dzhokhar Tsarnaev and his 26-year-old brother Tamerlan ‘were going to attack  other individuals’ — and Davis says that’s based on the evidence at the scene  and the cache of weapons the brothers had at their disposal.

However, Davis claims releasing photos of the  two Boston Marathon bombing suspects ‘forced them out of their hideout’ and  spurred them into Thursday and Friday’s deadly night time car chaos and gun  battle with law enforcement.

‘It forced them out of their hideout and they  decided to commit further violent acts. But it’s my belief that they were  already manufacturing explosive devices. Further violent acts were inevitable,’  Davis told The Boston  Globe.

The suspects ‘were not making those  explosives for nothing,’ Davis told The Globe. ‘There was a plan there, and I  believe that tragically Sean Collier lost his life, but he was truly protecting  the citizens of the city’

Handguns, a rifle and at least six bombs,  three of which detonated were found at the scene on Friday after officers had  their first showdown with the Boston bombing brothers in Watertown,  Massachusetts.

And it is believed that federal prosecutors  are putting the final touches together on charges against Dzhokhar Tsarnaev,  despite his throat wound leaving him unable to speak.

The most serious charge available to federal  prosecutors would be the use of a weapon of mass destruction to kill people,  which carries a possible death sentence. Massachusetts does not have the death  penalty.

CBS  News‘ John Miller has claimed  investigators believe the wound to the back of his neck is evidence that  Dzhokhar attempted to end his own life at the culmination of Friday’s dramatic  standoff.

‘They say it appears from the wound that he  might have stuck a gun in his mouth, and fired and actually just went out the  back of his neck without killing him.’

Dzhokhar Tsarnaev and his  26-year-old  brother Tamerlan ‘were going to attack other individuals’ —says  Boston police commissioner Davis and  says that opinion is based on the evidence  at the scene and the cache of weapons  the brothers had at their  disposal.

Planning further atrocities?: Dzhokhar Tsarnaev and his  26-year-old brother Tamerlan were believed to be about to unleash further terror  attacks on Boston according to the city’s police commissioner

Handguns, a rifle and at least six bombs,  three of which detonated were discovered at the scene on early friday after  officers first came face-to-face with the Tsarnaev brothers on a residential  street in Watertown, Massachusetts.

Police chief Edward Deveau revealed that a  lone officer was the first to encounter Tamerlan and Dzhokar Tsarnaev and that  before he could call for back-up, the two brothers exited the Honda and BMW’s  they were driving and began firing.

‘They jump out of the car and unload on our  police officer,’ said Deveau.

‘They both came out shooting — shooting  guns, handguns. He’s under direct fire, very close by. He has to jam it in  reverse and try to get himself a little distance.’

Eventually, five other officers, including  two off-duty cops arrived and there began a close quartered gun-fight in a ‘very  tight area’ in the middle of suburban Watertown.

‘We estimate there was over 200 shots fired  in a five- to 10-minute period,’ said Deveau.

He also revealed that the two brothers  detonated a pressure cooker bomb – lending credence to the theory that the  brothers were planning further terrorist strikes across the city.

‘We find the pressure cooker embedded in the  car down the street, so there’s a major explosion during this gunfight (with) my  officers — six of my officers that I’m extremely proud of,’ Deveau  said.

The pair also threw two other ‘rough’ and  crude explosives at the officers, by lighting them.

And then at the culmination of the gun fight,  Tamerlan Tsarnaev begins to advance on the pinned down officers.

He all of a sudden comes out from under cover  and just starts walking down the street, shooting at our police officers, trying  to get closer,” Deveau said. “Now, my closest officer is five to 10 feet away,  and they’re exchanging gunfire between them. And he runs out of ammunition —  the bad guy — and so one of my police officers comes off the side and tackles  him in the street.

‘We’re trying to get him handcuffed. There’s  two or three police officers handcuffing him in the street — the older brother.  At the same time, at the last minute — they obviously have tunnel vision, it’s  a very, very stressful situation — one of them yells out, ‘Look out!’ and here  comes the black SUV, the carjacked car, directly at them,’ said  Deveau.

‘They dive out of the way, and he (the  younger brother) drives over his brother and drags him a short distance down the  street.’

Tamerlan was pronounced dead later on at  hospital and Dzhokar drove off in the Mercedes SUV about two blocks and then  exited the car and ran off into Watertown.

This comes as previously unseen video of the  dramatic capture of the Boston bomber shows a police robot  ripping apart the  tarp concealing the suspect and numerous flash bang  grenades being thrown into  the boat where he lay.

In the final moments before his capture on  Friday night, Dzhokhar Tsranaev appeared to lay still inside a boat in a  backyard in Watertown, Mass. on Friday before he was taken into custody.

Doctors also revealed grizzly details on how  his brother, Tamerlan, had wounds from head to toe, ‘every region of his body had injuries [though] his legs and arms were  intact,’ they  said about his condition when he was hospitalized on  Friday morning shortly  before he died.

Watertown police chief Edward Deveau  has  also given the most detailed yet account of events on Friday. Boston had been on  edge after two  bombs ripped through the crowd near the finish line of the  Boston  Marathon on Monday. The city was  gripped with fear as the suspects were being hunted down, after the FBI  released photos of the men behind the attacks on Thursday night.

Violence broke out in the early morning hours  Friday when police received reports  of a robbery of a convenience store in  Kendall Square near MIT and a Sean Collier, an MIT police officer, was shot multiple  times.

Speaking to CNN following Dzhokhar’s  capture, Deveau said that a single officer was the first to encounter  the two  cars that Tamerlan and Dzhokhar Tsarnaev were driving, just  before 1am Friday.

One of the vehicles was a Mercedes SUV the  brothers had carjacked earlier that night.

Before the officer could call for backup, the  two cars came to a stop and the brothers got out.

‘They jump out of the car and unload on our  police officer,’ Deveau said.

‘They both came out shooting — shooting  guns, handguns. He’s under  direct fire, very close by. He has to jam it in  reverse and try to get  himself a little distance.’

Five others officers arrived on the scene in  the middle of an intense  shootout during which Deveau says over 200 rounds were  fired in 5-10  minutes.

The chief  said that one of the suspected  bombers lobbed an explosive at the  officers, which later turned out to be a  pressure cooker bomb like the  ones used in the marathon attack Monday.

The brothers also allegedly threw  other  explosives at police, which Deveau described as ‘very rough  devices.’

Two of the bombs detonated and two did not.

The pressure-cooker bomb exploded, and the  lid was found embedded in a nearby car, Deveau said.

At one point, the older brother came directly  toward police, firing a gun  at officers as he inched closer toward him, but  Tamerlan Tsarnaev’s luck ran out along with his ammunition, allowing one of the  officers to  tackle him.

The older of the two Chechen brothers  suspected of bombing the Boston Marathon was wounded but alive following a  police gun battle when his younger brother ran him over with a car,  possibly  causing his death.

‘He all of a sudden comes out from under  cover and just starts walking down the street, shooting at our police officers,  trying to get closer,’ Police Chief  Edward  Deveau, of Watertown, Massachusetts, said.

‘Now, my closest officer is five to 10  feet  away, and they’re exchanging gunfire between them. And he runs out  of  ammunition — the bad guy — and so one of my police officers comes  off the  side and tackles him in the street.’

He was in the process of being  handcuffed by  two or three officers when his younger brother,  19-year-old Dzhokhar, jumped  behind the wheel of a black SUV the two  hand allegedly carjacked earlier and  barreled toward the group.

The older of the two Chechen brothers  suspected of bombing the Boston Marathon was wounded but alive following a  police gun battle when his younger brother ran him over with a car,  possibly  causing his death.

Officers who were restraining  Tamerlan  Tsarnaev got out of the way of the speeding vehicle, which  ended up driving  over the wounded suspect, the police chief told CNN.

According to Deveau, the 19-year-old suspect  dragged his sibling’s body a short distance down the street and drove off.

He later ditched the SUV and escaped on  foot.

‘I am extremely lucky that I’m not at a  funeral this morning for one of my officers,’ Deveau said in an interview on  MSNBC.

‘They were heroic, very talented, and had the  guts and glory to defend our town, our community, in a very tight  situation.’

Suspects: Tamerlan Tsarnaev, 26, left, was reportedly  run over by his accomplice and younger brother Dzhokhar Tsarnaev, 19

Tamerlan Tsarnaev was pronounced dead at a  hospital a short time later.

An alleged autopsy photograph of Tamerlan  that was leaked Friday shows  multiple gunshot wounds and a massive open gash  that spans from the  center of his chest to his back.

Another smaller gash is located right below  the larger wound. His right shoulder and his face show signs of hemorrhaging.

A doctor involved in treating the Boston  Marathon bombing suspect who  died in a gunbattle with police told the  Associated Press that Tamerlan Tsarnaev  had injuries from head to toe and all  limbs intact when he arrived at the hospital.

Dr David Schoenfeld said 26-year-old  Tamerlan Tsarnaev was unconscious and had so many penetrating wounds  when he  arrived at Beth Israel Deaconess Medical Center early Friday  that it isn’t  clear which ones killed him, and a medical examiner will  have to determine the  cause of death.

The older  Tsarnaev’s clothes had been cut  off by emergency responders at the  scene, so if he had been wearing a vest with  explosives, he wasn’t by  the time he arrived at the hospital, the doctor  said.

‘From head to toe, every region of his body  had injuries,’ he said.

‘His legs and arms were intact – he  wasn’t  blown into a million pieces’ – but he lost a pulse and was in  cardiac arrest,  meaning his heart and circulation had stopped, so CPR,  or cardio-pulmonary  resuscitation, was started.

Schoenfeld did not address the police assertion that Tsarnaev was run over by a car driven by his brother as  he fled  the gunfire.

The doctor said he couldn’t discuss specific  treatments in the case except  to say what is usually done in such  circumstances, including putting a  needle in the chest to relieve pressure that  can damage blood vessels,  and cutting open the chest and using rib-spreaders to  let doctors drain  blood in the sac around the heart that can put pressure on  the heart and keep it from beating.

‘Once you’ve done all of those things … if  they don’t respond there’s  really nothing you can do. You’ve exhausted the  playbook,’ he said.

After 15 minutes of unsuccessful treatment,  doctors pronounced him dead at  1:35am.

His body was turned over to law enforcement  for examination to  determine the source of his injuries.

‘We did everything we could’ to try to save  his life, Schoenfeld said.

‘There was some discussion in the emergency  room about who it was. That discussion ended pretty quickly,’ Schoenfeld said.

‘It really doesn’t matter who the person is.  We’re going to treat them as best we can.’

Evidence: Investigators gather evidence on Saturday,  near the location in Watertown, Mass., where Dzhokhar Tsarnaev, 19, was  captured

Review: Investigators remained at the home in Watertown,  Mass. where the surviving suspect was located

After the early morning violence, officials  frantically searched for the suspect who remained on the loose.

The city issued a ‘shelter-in-place’ request,  telling residents of the greater Boston area while the streets were overun with  an estimated 1,000 law enforcement officers who scoured the are for the  fugitive.

Shortly before 6pm, officials announced that  though they hadn’t located the alleged  bomber, Dzhokhar Tsarnaev, they were  lifting the lockdown and urged residents to exercise extreme caution and be  vigilant.

One Watertown, Mass. resident took that  advice to heart.

After 6pm, David  Henneberry walked out to his backyard and noticed something odd about his  boat, that is stored behind his home.

‘He looked and noticed something was off  about his boat, so he got his  ladder, and he put his ladder up on the side of  the boat and climbed up, and then he saw blood on it, and he thought he saw what  was a body  laying in the boat,’ Henneberry’s neighbor, George Pizzuto told ABC  News.

‘So he got out of the boat fast and  called  police.’

Authorities then used a helicopter  equipped  with a thermal imaging device to confirm that there was a body  in the tarp  covered boat and that the person was alive.

Hovering over the area, the helicopter  spotted the heat signature of a person, confirming Henneberry’s  suspicions.

‘Our helicopter had actually detected  the  subject in the boat,’ Col. Timothy Alben of the Massachusetts State  Police told  NBC News. ‘We have what’s called a FLIR — a forward-looking  infrared device —  on that helicopter.

The chopper  monitored the body in the boat  for more than an hour before police moved in.

ATF, SWAT and  K-9 units had descended upon  67 Franklin Street and engaged Tsarnaev in a vicious gun battle – over 40 shots  rang out in the quiet suburban  neighborhood.

‘There was an exchange of gunfire,’ confirmed  Boston Police Commissioner Ed Davis at a news conference.

‘We used a robot to pull the tarp off the  boat,’ David Procopio of the  Massachusetts State Police said to CNN.

Unconfirmed reports suggest that  Tsarnaev  was shot twice by law enforcement in the gun battle which raged until his  capture at approximately 8:45pm.

Law enforcement sources have suggested that  Tsarnaev gave himself up  voluntarily after realizing continuing resistance was  fruitless.

He was found bleeding heavily from gunshot  wounds to his neck and foot  from the shoot-out on Friday morning, which he  escaped on foot before taking up his hiding place in a Watertown backyard boat.

The blood loss  would have taken place over  more than 20 hours by the time he was found and there were reports,  which could  not be confirmed, that he may have been shot a further two  times last  night.

‘He had lost a lot of blood. He was so weak  that we were able to just go in and scoop him up,’ state police spokesman David  Procopio told the  Boston Herald adding that the suspect was in ‘serious if not  critical  condition’.

He was rushed from the scene by ambulance  and images showed apparatus being used to help him breathe.

As the suspect receives treatment at the Beth  Israel Deaconess Medical  Center in Boston, law enforcement officials have  revealed that he  injured his throat in the standoff with police and may not be  able to  speak, a law enforcement official toward CNN.

Massachusetts Governor Deval Patrick said on  Friday : ‘[I] hope he survives, because we have a million questions.’

Tsarnaev was captured last night in  the  culmination of a dramatic week-long police hunt and a completely  unprecedented  $333 million shutdown of Boston and its suburbs.

The medical facility where he is a  patient  is under heavy armed guard and federal prosecutors are standing  by at the  center for when the teenager is able to speak.

Victims who were injured in the  deadly blast  at the marathon on Monday are also among those being  treated at the medical  center, which has some families angry about the  close proximity to the alleged  mastermind.

Tsarnaev is being treated in a room  yards  from where 11 injured marathon victims are still in recovery while a specially  drawn up High-Value Detainee Interrogation Group wait  anxiously to question  him.

One Boston mother, Liz Norden’s two  sons,  Paul and J.P., were in the crowd at the race on Monday and have  both lost a leg  in the aftermath of the tragic event. Her younger son, Paul, is being  treated at Beth Israel Deaconess Medical Center.

She told NBC News that she is shocked and  angry that the suspect is so near.

‘I can’t even tell you how devastating it’s  been,’ Liz Norden told NBC News. ‘Those two [the bombers] shattered my  world.’

Chaos in the streets: Gunfire erupted in a quiet  suburban neighborhood, setting off a massive manhunt

The showdown in Watertown broke out after the  violence began in Cambridge, Mass.

Violence erupted in the early morning hours  Friday when police received reports of a robbery of a convenience store in  Kendall Square near MIT and a police officer was shot and  ended up with a gun  fight in a small suburban street as residents slept.

Sean Collier, an MIT police officer, was shot  multiple times while in his  cruiser at Main and Vassar streets, near the Stata  Center on the MIT  campus.

Officials told the Washington Post that  footage from a security camera shows the two suspects approaching the car and  speaking to the officer.

All of a sudden, one of the suspects pulled a  gun and shot Collier multiple times, including one shot to the head.

Some police have suggested that the shooting  was meant to spark a full scale confrontation with police.

‘They were looking to start something,’ one  official told the Washington Post.

The 26-year-old Collier was pronounced dead  at Massachusetts General Hospital.

A short time later, the two men carjacked a  Mercedes SUV at gunpoint.

The  hostage was then driven around for half an hour as the pair decided what their  next move would be.

As police moved in on the vehicle following  reports of a carjacking, the pair decided to dump the driver at a gas station on  Memorial Drive in Cambridge.

The search for the vehicle led to a chase  that ended in Watertown, where authorities said the suspects threw explosive  devices from the car and exchanged gunfire with police.

Richard H. Donahue, 33, a transit police  officer was seriously injured during the chase.

In Watertown, witnesses reported hearing  multiple gunshots and explosions at about 1am on Friday, when the frightening  scene occurred.

On Saturday, Boston police paid tribute to  the MIT officer who died in the line of duty.

Mr Collier’s body was transported from the  Boston medical examiner’s office to the deceased man’s hometown of  Wilmington.

Officers and local residents lined the street  to remember the slain officer as his body left the office.

His family had asked that the hearse, with a  police escort, pass through the center of hometown before  heading to a funeral  home in Stoneham.

A vigil was held in his hometown of  Wilmington on Saturday night, as residents flocked to the streets in remembrance  of the hero, who was shot multiple times  by the suspects.

The Collier family said that the 26-year-old  had always wanted to be a police officer.

‘We are heartbroken by the loss of our  wonderful and caring son and brother, Sean Collier. Our only solace is that Sean  died bravely doing what he committed his life to – serving others,’ his family  said in a statement.

Mr Obama similarly offered his condolences to  the Collier family on Friday night, after the surviving suspect was captured.

‘He died bravely in the line of duty  doing  what he committed his life to doing, serving and protecting  others,’ the  president said.

Boston Strong: Fans hold an American flag during  ceremonies in tribute of victims and first responders to the Boston Marathon  bombings before a baseball game between the Boston Red Sox and the Kansas City  Royals

The Red Sox paid an emotional tribute to the  people of Boston on Saturday afternoon in a moving pregame ceremony at  Fenway  Park, the first time since last Monday’s deadly terrorist attacks that killed  three and left more than 180 wounded.

Designated hitter David Ortiz exclaimed ‘this  is our f***ing city’ to rapturous  cheers, and some tears, after a moving video,  encapsulating the horror  and heroism of the past few days, played on the big  screen.

Proud Bostonians could be seen watching the  game, many of them clutching  American flags.

The city used the significant sporting event  to honor  the victims and offer gratitude to the police, firefighters and  medical  personnel as well as strangers who risked their lives to save others  after the senseless attacks.

‘All right, Boston,’ said Ortiz. ‘This jersey  that we wear today, it doesn’t say Red Sox. It says Boston.

He continued: ‘We want to thank you, Mayor  Menino, Governor Patrick, the  whole police department for the great job they  did this past week. This  is our f***ing city, and nobody is going to dictate  our freedom. Stay  strong.’

The Boston team,  rather than wearing their  traditional ‘Red Sox’ embroidered across the  chest, wore crisp white uniforms  that simply read ‘Boston,’ with a ‘B  Strong’ logo.

The team said their uniforms would be  autographed and  auctioned to raise money for the charity established to help  the  victims, called One Fund Boston.

During the video, the crowd applauded when  images of the brave Carlos Arredondo appeared on the screens and  it increased  when pictures and quotations from President Obama, Governor Patrick and Mayor  Menino were shown.

It was accompanied by Jeff Buckley’s  rendition of ‘Hallelujah.’

When the footage moved to the manhunt for  19-year-old Dzhokar A Tsarnev in Watertown, the fans were on their feet  cheering.

At that point, law enforcement and first  responders walked onto the field and formed a line in front of the Red Sox  dugout.

Moments of silence were then held for  Marathon victims, eight-year-old Martin  Richard, Krystle Campbell and Lu Lingzi  and MIT police officer Sean  Collier, who was killed Thursday night in a  shootout between the  Tsarnaevs.

The emotional tribute came after  baseball stadiums around the U.S. erupted  into cheers last night as news that  police had captured the second Boston  bombings suspect was plastered  across the big screens.
