Details are sketchy, but police said the coach was the target of the shooting at Mellon Park.

There were about a dozen children ages of 7 to 10 at practice when the coach was shot.

"It is very concerning. Bullets don’t have names on them and there were multiple shots fired, and by the grace of God, no one else got hit," Pittsburgh police Commander Mike Pilyih said.

According to police, a man went to the practice asking for the coach, then shot him several times.

"It appears to be a personal issue," Pilyih said. "They absolutely did know one another."

The coach was taken to the hospital in stable condition, but the shooter remains at large, police said.

"We have detectives who are working this whole scene and they are going to check video here and along here to see if we can get any evidence from that," Pilyih said.
