Hier ein Auszug des (korrigierten) Ablaufs bei der Verhaftung von der NY-Times. Link zum Artikel ganz unten.
"A little later, Mr. Henneberry decided to return to the boat. “So he brought a ladder out of the garage and laid it against the boat,” Mr. Duffy, who has talked to Mr. Henneberry several times about the episode, said in an interview. “He took about three steps up the ladder and looked inside the boat and sees blood on one side of the deck. And he is questioning himself, ‘Did I cut myself the last time I was out here?’
“Then he sees blood on the other side of the deck,” Mr. Duffy said. “Then he looks over the engine compartment and sees a body. His words were, ‘I levitated off the ladder.’ He does not remember going back into the house. He told his wife, ‘Lock the doors,’ and he called 911.”
A call went out over the police radio. “They have a boat with blood on it, and they believe someone’s on the boat,” it said. Police officials initially said the boat was in the backyard of a house just outside the perimeter of the area where investigators had conducted door-to-door searches all day. But Commissioner Davis, of the Boston police, said this week that the boat had been inside the perimeter.
“It was an area that should have been checked,” he said. “We are not sure how long he was in the boat. There was a pool of blood near where the car was dumped about four or five blocks away from the boat.”
It is still not clear what prompted officers to fire into the boat. “Shots fired, multiple shots!” someone was heard saying on the radio, before another call went out: “All units hold your fire! Hold your fire.”
Commissioner Davis said that “we will have to see what prompted the volley of shots before the cease-fire was ordered by a superintendent of the Boston police.”
A state police helicopter used thermal imaging technology to show where the suspect was hiding in the boat, and a robotic arm attached to a police vehicle was used to pull the tarp back.
Then, around 8:45 p.m., Dzhokhar Tsarnaev was taken alive."
