BOSTON (CBSNewYork/AP) — At least three people were killed and 144 others injured Monday after two explosions went off near the finish line of the Boston Marathon, police said.
Boston Police Commissioner Edward Davis said at an afternoon news conference that the “simultaneous explosions” occurred at 2:50 p.m. — about three hours after the winners crossed the line.
An 8-year-old boy is among the dead, CBS 2 sister station WBZ-TV in Boston confirmed. Further details about the deceased were not immediately available.
CBS 2 reported that of those injured, seven victims were listed in life-threatening condition at Beth Israel Deaconess Medical Center. Eight others were listed in critical condition at Massachusetts General Hospital and Brigham & Women’s Hospital.
“It’s sheer chaos,” one woman told WBZ-TV. “I can only imagine it’s similar to what happened on 9/11 in New York.”
Officials said earlier Monday afternoon there was no suspect in custody. However, CBS News’ John Miller reported later that an individual, a Saudi national, was in custody and was reportedly being cooperative and denying involvement.
Miller reported the man was seen “acting suspiciously.” He was eventually apprehended by a bystander and turned over to Boston Police and was being questioned by FBI.
“A civilian who thought this individual was acting suspiciously chased him down and tackled him, and then turned him over to Boston police saying, ‘I saw this guy hanging around over there acting suspiciously and then he ran,’” Miller said.
Sources told CBS News that authorities were also studying video from a closed-circuit camera, showing a possible person of interest seen walking with two backpacks.

The two main blasts were caught on video. A sharp, thunderous crack can be heard, followed by a towering plume of white smoke. The explosions went off right near the finish line, sending runners to the ground.
As CBS 2’s Lou Young reported Monday night, the first blast was so strong, one runner who appeared to be an older man tumbled to the ground.
Some 15 seconds later, a second explosion is seen going off about a block away.
The blasts triggered panic, as runners who had been making their way to the finish line suddenly began racing for their lives from the blast scene.
Competitors and race organizers were crying as they fled the chaos of the blasts along the route. Bloody spectators were being carried to the medical tent that had been set up to care for fatigued runners.
First responders rushed to help victims trapped in the tangled debris. Some had limbs ripped away by the blast, officials said.
Video of the scene showed injured people and what appears to be several demolished viewing stands. The explosions took place near the Fairmount Copley Plaza Hotel.
