Boston bombings suspect identified on video, says official
BOSTON // In what could be major break in the Boston Marathon case, investigators are on the hunt for a man seen in a department store surveillance video dropping off a bag at the site of the bombings, a local politician said last night.
Separately, a law enforcement official confirmed that authorities have found an image of a potential suspect but do not know his name.
The development - less than 48 hours after the attack, which left three people dead and more than 170 wounded - marked a possible turning point in a case that has investigators analysing photos and videos frame by frame for clues to who carried out the twin bombings and why.
City Council President Stephen Murphy, who said he was briefed by Boston police, said investigators saw the image on surveillance footage they got from a department store near the finish line and matched the findings with witness descriptions of someone leaving the scene.
"I know it's very active and very fluid right now - that they are on the chase," Mr Murphy said. "They may be on the verge of arresting someone, and that's good."
The bombs were crudely fashioned from ordinary kitchen pressure cookers packed with explosives, nails and ball bearings, investigators and others close to the case said. Investigators suspect the devices were then hidden in black duffel bags and left on the ground.
As a result, they were looking for images of someone lugging a dark, heavy bag.
One department store video "has confirmed that a suspect is seen dropping a bag near the point of the second explosion and heading off," Murphy said.
A law enforcement official who was not authorised to discuss the case publicly and spoke to the Associated Press on the condition of anonymity confirmed only that investigators had an image of a potential suspect whose name was not known to them and who had not been questioned.
Several media outlets reported that a suspect had been identified from surveillance video taken at a Lord & Taylor department store between the sites of the bomb blasts.
The turn of events came with Boston in a state of high excitement over conflicting reports of a breakthrough.
A law enforcement official briefed on the investigation told the AP around midday that a suspect was in custody. The official, who was not authorised to divulge details of the investigation and spoke on the condition of anonymity, said the suspect was expected in federal court. But the FBI and the US attorney's office in Boston said no arrests had been made.
By nightfall, there was no evidence anyone was in custody. No one was taken to court. The law enforcement official, who had affirmed there was a suspect in custody even after federal officials denied it, was unable to obtain any further information or explanation.
At least 14 bombing victims, including three children, remained in critical condition. Dozens of victims have been released from hospitals, and officials at three hospitals that treated some of the most seriously injured said they expected all their remaining patients to survive. A two-year-old boy with a head injury was improving and might go home today, Boston Children's Hospital said.
