(INDIANAPOLIS) - Investigators asked Tuesday for video and pictures from the public, to help them determine who set off two bombs near the finish line of the Boston Marathon.
Teresa Mackin of WISH TV8 reports that a local FBI agent explained to 24-Hour News 8 that these pictures, surveillance videos from nearby businesses, and videos from citizens, may be the clues investigators need.
Investigators plan to go over those videos and pictures, from before and after the attack, frame by frame.
"Stop and think of any incident that's happened, in the last four or five years, that somebody didn't come up with a video," said William Ervin, who retired as Special Agent in Charge of the FBI in Indianapolis in 1990. "They may get very fortunate by getting a response from those people."
Ervin was also the Special Agent in Charge in Honolulu, before Indianapolis.
He investigated after the 1982 bombing of a Pan American flight that landed in Hawaii. He says the suspect in that case was just released from prison.
Images Will Play Important Role in Investigation
Ervin says in Boston, investigators are now pouring over important images, finding all witnesses, and detailing the crime scene.
"I'm sure they did some kind of examination of all the packages left everywhere," he said. "At the same time, they're examining the bomb. They're taking it apart, seeing what it's made of, and seeing if they have that as a pattern of any other bombings."
"They'll put together some evidence pretty quickly in two or three days, maybe not enough to find the perpetrator, but enough to help get a much better idea of what it was."
He also says he is wondering if anyone will eventually claim credit from this.
Ervin says the type of bombs used are similar to bombs used in the Iraq war.
Doctors found nails and pellets, among other items, in the wounds they treated.
"That means somebody wanted to create a lot of bodily injury , to as many people as possible," said Ervin.
He believes investigators will solve the case.
"They have a whole lot of talent working on this in Boston," said Ervin.
