David McIntyre, an honor student was playing video games with his older brother, C.J., when there was a knock at the front door of their apartment in Mount Oliver.

Someone standing in the doorway began shooting.

C.J. was also shot six times, but he survived. David was fatally wounded.

Their mother was in another room and heard one shot and then several more. She came running into the room to find her sons on the floor.

“I grabbed his hand, and I’m saying, ‘David, it’s mommy, squeeze my hand. David, it’s mommy, squeeze my hand,’ and he’s not squeezing back,” said McKnight. “I knew by his look that he was gone, but I didn’t internalize it. I didn’t want to believe it.”

She says the fact there’s been no arrest a year later is beyond frustrating.

“How could no one see nothing or hear nothing? I still can hear the sound of that gun,” said McKnight. “Turn this person in, turn yourself in. If you know who did it, turn this actor in cause what if it were your son?”

C.J. describes the gunman as a white man, about six-feet tall, with a thin build, dark hair and wearing a black hoodie.

There’s still a reward offered in the case through Crime Stoppers at 412-255-8477.
