At 9:50 a.m., a white male, approximately 50 years old, 6 feet tall, wearing running attire was found on the track.
"He doesn't have any identification," Chief David Wayman said. "It is believed that he does jog there regularly. It is also believed that he runs there from his residence as there is no vehicle present. It is believed that he collapsed from a heart attack and he is currently being treated at Overlook Hospital."
Wayman said the WPD wants to make every attempt to contact friends and family but needs the public's help.
If anyone believes they may know the identity of the man, please contact the WPD at 908-789-4000.
