Pennsylvania State Police say they found writings left by ambush suspect Eric Frein (freen) that describe how he opened fire on a rural barracks and then made his escape.

Lt. Col. George Bivens read from the journal he says was written by Frein. He says Frein wrote that he took two shots, watched his victim fall "still and quiet," then shot a second trooper. He says Frein wrote he tried to make his getaway in a Jeep, but ran it into a swamp and took off on foot. He says Frein called the botched getaway a "disaster."

Bivens says the note provided a "cold-blooded and absolutely chilling account" and described Frein's actions as "pure evil."

Bivens gave an update on the manhunt Wednesday, 26 days after the late-night ambush that killed Cpl. Bryon Dickson and seriously wounded Trooper Alex Douglass.
