Pennsylvania State Police say that the doorbell video footage released by police Friday of escaped fugitive murder suspect Michael Charles Burham walking past a home turned out not to be him after further investigation.

"We can now also say with relative certainty that thanks to the public response to the aired video that the individual depicted was not Michael Burham," PSP Lt. Col. George Bivens said in a press conference Saturday afternoon. "We have a strong reason to believe that he is still in the area."

Police say the self-taught survivalist "is prepared to survive outdoors."

Despite the earlier released video not being Burham, police encouraged residents in northwestern Pennsylvania and western New York to regularly review their home's surveillance cameras and report any suspicious behavior to police.

"I continue to ask residents of northwestern Pennsylvania and western New York to regularly review their doorbell and surveillance cameras footage for anything they think is helpful to this search," Bivens said.

Authorities also told residents to be on the lookout for small stockpiles and campsite remains.

"As people hike or otherwise spend time in the woods this weekend and beyond, we ask that they notify us if they find any stored packages or apparently abandoned campsites," Bivens said.

Burham, an Army veteran with survivalist and firearms training, was being held on kidnapping and related charges and is also suspected of murder and rape in New York in an interstate crime spree that ended in his arrest in South Carolina after a previous manhunt in May.

He made his way though the jail's gym to the rooftop on July 6, where he was able to climb down with a rope made from bedsheets, according to authorities.

Then he snuck off in a denim jacket and jail issued orange-striped jumpsuit and matching Crocs at around 11:20 p.m., police said. But he may have changed his clothes along the way, wit more than 150 officers from state, local and federal agencies were looking into reports of possible sightings in both states.
