Aaron Hern, a 11-year-old from Martinez, was injured during Monday's Boston Marathon bombings. Hern was waiting at the finish line for his mother, Katherine Hern, 40, who was about 200 feet away from the finish line when the bombs went off. He was hit in the thigh by shrapnel from the first bomb.

According to Contra Costa Times, "The boy was taken to Boston Children's Hospital, where he underwent surgery to remove the shrapnel."

ABC has more:

Aaron was in the middle of the chaos, severely wounded by shrapnel that dug right to the bones in his thigh and hip. His father was nearby on the reviewing stand while Aaron was at street level waiting for his mother who was a few hundred yards from finishing the race.

"Dad was up on the bleachers looking down and the crowd got chaotic and he found him lying down," said Sides.

Aaron will be in the hospital at least a week recovering from his injuries.

The Boston Marathon bombs, as Gothamist reports, were pressure cookers packed with nails and ball bearings. The pressure cookers cum bombs were placed in black nylon bag or backpacks and dropped in specific locales prior to ignition. The FBI are still trying to determine who is responsible for the attacks that killed 3 and left more than 175 injured.
