Watch as KDKA’s Briana Smith reports:

“I’m just so sad this happened. Guns got to be locked up because kids don’t know they think they are toys, and they have to be locked up because this is what happens,” said Shari Robinson.

Alfred and Shari Robinson couldn’t hold back tears after learning about the heartbreaking incident that happened at their next-door neighbors’ home on Prescott Drive around 5:30 pm. on Monday.

“They are nice kids, very nice kids, always speaking, very manner-able. I just can’t believe it. It’s just horrible, it’s hard,” Alfred Robinson.

Allegheny County homicide detectives and Penn Hills police are investigating what happened.

“The initial investigation shows there was children playing in a back bedroom when one of the children was shot. We’re still working to figure out how that occurred, but the child was pronounced deceased at a hospital,” said Lt. Venerando Costa with the Allegheny County Police Department.

The Penn Hills Police Department is providing emotional support teams for the officers who responded to the tragic shooting.

The Penn Hills School District is also making counselors and social workers available to any students and staff who need extra support.

“It’s always hard when its children, just is. They’re innocent so that’s why it’s always tough,” Costa said.

The Robinson’s want the family to know they are here for them.

“Just praying for the family, hope they make it through,” said Alfred and Shari Robinson.

The gun appears to be legally owned by a parent who is cooperating with the investigation, Allegheny County police said.

Police will be turning over facts of the case to the Allegheny County District Attorney’s Office to determine if there’s any culpability.
