BLOOMING GROVE, Pa. (AP) —  Authorities found a journal left by ambush suspect Eric Frein that describes how he opened fire on a rural barracks — watching one of his victims fall “still and quiet” — and then made his escape, authorities said Wednesday.

Frein wrote how he “got a shot around 11 p.m. and took it. He dropped. I was surprised at how quick,” according to Lt. Col. George Bivens, who read from the multipage journal that authorities said they found last week at a campsite used by Frein.

The journal describes how Frein fled in a Jeep, but ran it into a swamp and took off on foot, a botched getaway Frein termed a “disaster,” said Bivens, who described the document as a “cold-blooded and absolutely chilling account.”

The journal was found Sept. 29, when authorities discovered a campsite at which they also found explosives, ammunition, food, water and clothing.

Hundreds of law enforcement officials have been looking for Frein — described by authorities as a survivalist and expert marksman with a grudge against law enforcement — in the woods around his parents’ home in Canadensis, in the Pocono Mountains.

Officers believe they have spotted Frein in the woods, but the distance and rugged terrain allowed him to slip away.

The most recent sighting came Tuesday afternoon, when an officer thought he spotted a brief glimpse of Frein from about 200 yards away, Bivens said. That was the fourth sighting by police or the community since Friday, he said.

“We will get Frein. Whether that is today, whether that is tomorrow or whether that is next week, remains to be seen,” Bivens said.
