With three homicides in three days, a community advocate in Syracuse says he's had enough.

Between Saturday and Monday, two men and a woman were killed in the city.

Clifford Ryan, the founder of OG's Against Gun Violence, decided to speak to a group of kids at Mundy Branch Library about the homicides. Ryan says he feels it's critical to reach out to youth, so that they can know guns are wrong from a young age.

He also spoke about staying out of gangs, resisting peer pressure and stopping the stigma about working with the police.

Ryan lost his son to gun violence in Syracuse in the 1990's.

When the children were asked if they ever knew anyone that's been shot or killed by a gun, almost every hand went up.
