Authorities Seek Dark-Skinned Possible Foreign National in Boston Investigation

Tried to enter a restricted area

Authorities say they are searching for a darker skinned or black male with a black backpack and black sweatshirt, possibly foreign national from the accent of the individual. Five minutes before the first explosion, officials said this person attempted to gain entry to a restricted area. When turned away, he broke eye contact and pulled his sweatshirt hood over his head and left, officials said.

Law enforcement is also looking for a yellow Penske box truck that tried to gain access with "medical supplies" approximately 1 hour after the explosion.
