Police say they know who the shooter is and they’re looking for him, but will not release the name.

“Anybody that’s going to discharge a firearm on a city street and kill another human being, we consider armed and dangerous,” Ryan said.

Detectives say the victim’s 42-year-old father and 66-year-old grandfather were also shot once. They were hospitalized in stable condition.

Oglesby was set to graduate from Penn State this spring.
