When David Henneberry nipped outside for a cigarette, he had no idea it would lead to a bloody shootout in his back garden and the capture of the most wanted man in America.
Like thousands of other residents of Watertown, a sleepy middle-class suburb of Boston, the 66-year-old had been cooped up in his home, at 67 Franklin Street, since police imposed a curfew in the early hours of Friday.
The curfew followed a 2am gun battle just a few streets away that left Tamerlan Tsarnaev, 26, dead and his 19-year-old brother Dzhokhar on the run. A thousand police, SWAT teams, dog units and explosive experts had been going door-to-door as frightened residents were ordered to shelter inside their homes.

But by 5.30pm, Dzhokhar still hadn’t been found and the curfew was lifted.

Hero: David Henneberry had no idea he would find America's most wanted man hiding in his boat

Despite cool temperatures and intermittent rain, residents – many of whom had been locked inside their homes all day – began emerging on to the streets. Some jogged, others walked their dogs while most stood chatting to neighbours.
Mr Henneberry, whose ‘passion’ is his 24-ft white fibreglass Seahawk pleasure cruiser, strolled into his garden at 6.05pm – and immediately noticed the tarpaulin covering his prized boat had been disturbed.
Neighbour George Pizzuto said: ‘He got his ladder and put it up against the side of the boat and climbed up. He saw blood on it and what he thought was a body lying at the back. He immediately ran inside and called the police.
‘David was totally distraught and in shock. That boat’s his baby. He takes care of it like you won’t believe.’
Robert Duffy, Mr Henneberry’s stepson, added: ‘As soon as he saw the tarp on the boat he knew something wasn’t right. It was flapping in the wind and, when he got the ladder he realised one of the straps had been cut – not chafed, or unhooked but cut.'
‘He stuck his head under it and noticed a pool of blood and what he thought was a man’s leg. He saw someone crumpled up in a ball.’
Minutes later and all hell broke loose as around 300 police officers, FBI and SWAT teams descended on the quiet neighbourhood.
At 6.15pm police had cordoned off a three-block, area, erecting barricades and sending sharpshooters to ‘cover’ street corners and take positions on rooftops.  A police helicopter with heat sensors flew over the garden to verify there was a body inside the boat.

Just before 7pm, an FBI negotiating team rushed past the barricades at high speed. A police spokesman later said: ‘They were on stand-by all day to talk to the suspect. We always wanted to bring him out alive if possible.’
At 7.25pm there was a burst of gunfire as Dzhokhar and police exchanged more than 40 shots, quickly followed by a series of bangs as flash bombs were thrown into the boat to ‘smoke him out’.
A bomb squad robot was also sent in to peel back the tarpaulin, while FBI negotiators using megaphones attempted to talk Dzhokhar down. Police footage later showed the suspect surrendering. 
A source said: ‘The suspect waved his arms and officers made him lift up his shirt and lower his trousers to show he had no explosives strapped to his body. There was a very genuine fear that he might be wearing a suicide vest.’
AT 8.43pm, a SWAT team stormed in, dragging Dzhokhar out and to the ground. Watertown police chief Edward Deveau said that, at that stage, ‘he put up no resistance. He knew it was over.’

As the news filtered down to the terrified residents, cheers and applause could be heard as a man in the crowd began to chant: ‘USA! USA!’ The massed rank of police were seen grinning and  high-fiving each other.
At 8.45pm the tweet that everyone had been waiting for came when the Boston Police Department announced: ‘Suspect in custody.’ They later added: ‘CAPTURED!!! The hunt is over. The search is done. The terror is over. And justice has won. Suspect in custody.’
Shortly afterwards an ambulance was driven away carrying a badly injured Dzhokhar to the Beth Israel Medical Center in Boston –  the same hospital where surgeons had battled to save his brother.
Tamerlan had suffered multiple injuries, including gunshot wounds and ‘crush wounds’ caused after his brother drove over him during his escape.
Yesterday, one police officer, who declined to be named, told me: ‘It looks like the guy had suffered wounds the night before. Tonight he fired first and officers on the scene returned fire. I heard on the radio that he’s been hit in the neck and leg.’
