BUFFALO, N.Y. -- A 13-year-old girl was sitting on a porch only a few houses down from a vigil when she was hit in the chest by a stray bullet Thursday night, and Buffalo police say this incident is related to gang violence.

Another man was shot at the same time in the face, and he's in critical condition at the Erie County Medical Center.

Buffalo Police are continuing to investigate the double-shooting, which happened around 9:30 Thursday night near Grant and Breckenridge Streets.

"Our Buffalo Police surveillance cameras did capture some amount of video footage of the incident," said Buffalo Police Lt. Jeffrey Rinaldo Friday.

Buffalo Police also say they believe one or more of the people attending the vigil, near where the two victims were shot, are believed to have gang ties, and were the intended targets.

With the culture on the streets that it's not safe to snitch, police say it can be difficult to get information to make an arrest in cases such as this. A suspect is not in custody in connection to this double-shooting.

"That's true with gang members, there's this culture of 'we don't talk to police," Rinaldo said. "However, that doesn't seem to be the culture of the citizens in the city."

"We have had some very good witness cooperation in this case," Rinaldo added. "Unfortunately, it doesn't appear that the shooting appeared to happen from within the immediate vigil. It may have come from across the street or from another location. In cases like that it does take a little bit of time."

When 2 On Your Side asked Buffalo Mayor Byron Brown if this incident signals a need for more gang law enforcement, he responded:

"Buffalo has a significant law enforcement partnership, with law enforcement at the local level, at the state level and the federal level working very closely together."

He added that the city also, "takes every level of assistance that we receive."

Homicide detectives were at the scene Friday looking for more evidence and doing follow up interviews with potential witnesses.
