State Police say they are following up on video posted early Tuesday on the Facebook page of a person of interest wanted for questioning in connection with the murder of a Crawford County woman and her 10-year-old son.

A 21 second long "live" video appeared before 4 a.m. on the Facebook page belonging to Jack Elijah Turner, who has been the subject of a manhunt since Saturday night, when a family member found the bodies of 49-year-old Shannon Whitman and her 10-year-old son at their Randolph Township home in Crawford County.

Police believe Turner stole Whitman's car and is considered a person of interest in the homicides.

As of 9:30 a.m. Tuesday, State Police in Meadville said 21-year-old Turner had not been located, in spite of widespread searches that included Sandy Lake Borough on Monday.

The video on Turner's Facebook page is very dark but shows some movement accompanied by the sounds of insects and heavy breathing.

While some people have posted comments saying they believe the video shows that Turner ditched the car and is now on foot, State Police say they have no evidence that the vehicle has been abandoned.

Another comment purportedly posted by Turner on Facebook shortly before the bodies of Whitman and her son were discovered apologizes to his family, saying, “I'm so sorry I did this.” However, the post does not make clear what the apology is for.

Investigators in the Erie suburb of Millcreek Township believe Turner used that car in an armed robbery of a gas station following the murders. Police have released surveillance images of the vehicle and the suspect.

Police say the robbery suspect was wearing a blue and white matching sweatshirt and pants.

Turner is described as a white male with dark brown hair, brown eyes, 5' 11”, 145 pounds with a tattoo covering his right hand. Turner has trimmed eyebrows and frequently wears what appears to be diamond stud earrings in both ears.

He may be driving the missing car, described as a grey/silver 2009 Lincoln MKS sedan with license number KXW5126.

Anyone with information about Turner's whereabouts is asked to call PSP Meadville 814-332-6911.
