Surveillance video taken by cameras at Lord & Taylor on Boylston Street helped identify a suspect placing a bomb.

The Associated Press reports the suspect will be brought to court.

Mayor Menino confirmed that the investigation has made significant progress.

Authorities investigating the deadly bombings at the Boston Marathon have recovered a piece of circuit board that they believe was part of one of the explosive devices, and also found the lid of a pressure cooker that apparently was catapulted onto the roof of a nearby building, an official said Wednesday.

A law enforcement official briefed on the investigation confirmed to The Associated Press that authorities have recovered what they believe are some of the pieces of the explosive devices. The official spoke on condition of anonymity because this person was not authorized to publicly discuss evidence in the ongoing investigation.

A person close to the investigation previously told AP the bombs consisted of explosives put in 1.6-gallon pressure cookers, one with shards of metal and ball bearings, the other with nails.

An unclassified bulletin was sent Tuesday evening to law enforcement agencies across the country and said that the bomb inside the backpack was an “improvised explosive device (IED)” made out of a common pressure cooker.
