Cranberry Township resident Aiden Tanner, 19, died in a motorcycle crash on Route 51 in Pittsburgh on Friday evening, July 19.

The accident was reported just after 8:30 p.m., and Pittsburgh police, fire, and medical units responded to the scene. When they arrived, they found a Tanner unresponsive on the road. Medics pronounced him dead at the scene.

According to a report from Pittsburgh Public Safety, Tanner was wearing a helmet at the time of the crash and no other vehicles were involved.

Tanner was identified by the Allegheny County Medical Examiner. The crash is under investigation by the Pittsburgh Collision Investigation Unit.

“Speed is believed to be a factor,” City of Pittsburgh public information officer Cara Cruz said Sunday. “Beyond that, there is nothing I can add with respect to the investigation as collision investigations can take a very long time.”
