Police search for missing man after person heard yelling 'I'm lost' near Chester Creek in Upland

UPLAND BOROUGH, Pa. (WPVI) -- Search crews were near Delaware County's Chester Creek overnight Sunday after a person was reportedly heard yelling for help.

Police say a call came in around 7:50 p.m. on Sunday after someone reported hearing a man calling out for "help" and stating, "I'm lost."

Officers responded to the area of Front Street in Upland Borough, but by the time they arrived, officers said they were unable to hear any further yelling.

Officials said they believe the yelling could be from a missing person report for Theodore Johnson.

Marple Township Police were also called out to help assist in the search with their drone.

Search dogs and a water rescue task force were also deployed in the area.

However, after roughly five hours of searching the woods and banks of the creek, officials said they were unsuccessful in locating Johnson.

Officials say this remains an open and active missing person case. Anyone with information on Johnson's whereabouts is urged to call 911.
