BUFFALO, N.Y. -- Through the rain, the hail and the cold, they marched.

"I lost a son to murder," said Billie Webster, program manager for Buffalo SNUG Violence Prevention Initiative. "They killed my son years and years ago, so I know how a parent feels. So, for me to do this work, it's a blessing."

"We're out here because there's a young lady lying in ECMC hospital, fighting for her life because somebody just randomly came here and shot her," said Buffalo Peacemakers Coordinator James Giles.

The street: Roosevelt Avenue, the site of a shooting that left four teens injured last Friday. Police say there was a large crowd gathered outside in the 100 block when shots were fired from a vehicle.

Buffalo Peacemakers and Buffalo SNUG Violence Prevention Initiative organized Thursday’s march to get the community's attention and send a message.

Giles says the shooting happened outside a party, and wants people to call Peacemakers or the police if they're having large get-togethers so they can post up nearby and act as a deterrent. Those groups might not be the first that come to mind when making up a guest list, but he says it's an important precaution.

"Better to err on the side of safety. Better to have us and not need us than need us and not have us," said Giles.

"We need more," said Webster. "We need the whole city of Buffalo to come together, not just on the east side, because what happens on the east side affects the west side, the north side, the south side. All these kids dying in the streets, they're our kids, whether we like it or not."
