Paranormal Central Discusses The Famous Greasy Bigfoot Photograph

In 2011, Sanger founder Jeffrey Gonzalez presented photographs taken of strange impressions left on the windows of his pickup truck that was temporarily abandoned in a snow storm when he and several others were on a Bigfoot expedition over Memorial Day weekend in California's Sierra National Forest.

When the men returned to retrieve Gonzalez's truck, they were startled to discover the window markings -- including a large paw-like image -- and what they first thought was evidence of hair on two of the truck windows.

Gonzalez called in forensic/law enforcement photographer Mickey Burrow, who has spent 14 years as a qualified court photographic expert and crime scene processor.

"I immediately started wondering if there could be some DNA left behind, because if this thing put its face on the window, I thought there was probably DNA on there," Burrow told AOL.

"I've got the know-how. I've done it more than 5,000 times on crime scenes. In this case, I treated it like it was a vehicle that got burglarized.

"As I was looking at the windows, I told Jeff it looked like something came up to the truck, rubbed up against it, swiped along the side of it, and then just put its face up on the window and looked in -- that's what it looks like."
