Boston Marathon Bomb Blasts - 2 Dead, Dozens Injured, Person Of Interest In Custody.

(FoxNews) - At least two people are dead and 73 injured – including up to 10 with amputated limbs – after two bombs tore through the finish line of the Boston Marathon, according to the Boston Police Department.

Authorities were guarding a person of interest at a local hospital, sources told FoxNews.com. The person, who sources said was 20 years old, had severe burns, but authorities had not determined whether the person was a victim or a perpetrator. Boston Police Commissioner Edward Davis said during a press conference that no suspect is in custody.

The simultaneous explosions just before 3 p.m. and reports of two other unexploded devices found near the scene raised suspicions of a terrorist attack. Intelligence officials told The Associated Press two unexploded devices were being dismantled. Competitors and race organizers were crying as they fled the bloody chaos, while some witnesses reported seeing victims with lost limbs.
