UPDATE: The woman struck in the back is expected to survive.
Transit Police report a second victim of Monday's shooting has been found — and she also was simply a bystander. Police have also made two arrests.
Erik Bornermann, a friend of that victim, told Jamaica Plain News she was bleeding from the back of her head. She ran to Asticou Road after the incident.
Transit Police said that woman went to the E-13 Boston Police station showing a non life-threatening graze wound to the head. Transit Police do not believe at this time she was the intended victim.
Police at first reported not having heard of other victims. But a 62-year-old woman complained of back pain, bringing Emergency Medical Technicians to Forest Hills Station. It turns out the woman had been shot, and her injuries are considered life-threatening.
Transit Police believe the second victim also was not an intended target. Police detectives "are exploring the possibility the incident may be gang-related."
Police have arrested two 18-year-old men from Boston. Their names haven't yet been released.
A reporter for Jamaica Plain News was outside the station when he heard several loud bangs, which might have been gunshots. Teenagers ran from the scene.
Transit Police said a man fired the shots from the station exit leading toward the 39 Bus.
Emergency crews descended quickly on the station and nearby Asticou Road.
[Editor's note: We've learned since the initial posting that the woman's age was 62.]
