BOSTON (AP) - An 11-year-old California boy and a 9-year-old girl remain in critical condition at Boston Children's Hospital, two days after twin bombings at the Boston Marathon killed three people and injured more than 170.
The hospital says on Wednesday that a third patient, an unidentified 2-year-old boy with a head injury, is improving and may go home Thursday.
Aaron Hern of Martinez, Calif., has undergone multiple surgeries, including three to four hours of surgery on Wednesday to further treat his badly injured leg, including removing more shrapnel and damaged tissue.
His mother, Katherine, wrote on her Facebook page earlier in the week that Aaron's upper left thigh was badly injured. His 12th birthday is May 1.
The 9-year-old girl also has a severe leg injury. She has not been identified.
