JACKSON COUNTY, Ohio (WSYX/WTTE) -- Twelve days ago Chris Fraley got a call no parent should ever get.

His youngest son, Colin, a fifth grader at Hilliard Scioto Darby Elementary School, had gotten his hands on a gun -- with deadly consequences.

"It's horrific," Fraley said quietly.

"I don't want other parents to have to go through what I'm going through right now."

Now the grieving dad is on a mission.

He's calling it "Colin's Crusade," and is urging gun owners to keep their firearms locked up and secure.

Colin died after finding an unlocked gun at his mother and stepfather's house in Hilliard, something that angers Colin's father.

"Unfortunately, it's the parents responsibility not having the guns protected and secured. And ammunition not secured. We have to protect our children," he said.

Fraley said he's not anti-gun.

"I'm all for people owning weapons, but you need to protect them and secure them. Lock them up and keep your family safe. Save your babies."

Hilliard Police are investigating the case; no charges have been filed.
