Frein was convicted of first-degree murder of a law enforcement officer, attempted murder, terrorism and two weapons of mass destruction counts related to the small bombs he left in the woods during the manhunt.
The jury in Pike County Court needed about four hours to find Eric Frein guilty of all 12 counts in the murder of a state police corporal and wounding of a trooper a year and a half ago.
The gunman led authorities on a 48-day manhunt through the rugged Pocono Mountains before USA marshals caught him at an abandoned airplane hangar more than 20 miles from the barracks.
The defense, which called no witnesses and presented no evidence during the trial, is expected to call several witnesses, including Frein family members and experts, during the penalty deliberations. Frein could either receive a sentence of life in prison or the death penalty.
Frein shot Dickson in the chest and through the shoulders and spine from a distance of 87 yards, waited almost 90 seconds until Trooper Alex Douglass came to Dickson's aid and then shot him, too, Tonkin said.
"We can't make him a holy man but we will try to make him a man", Ruzzo said.
Prosecutors will ask the same jury that convicted Frein to send him to death row.
Pike County District Attorney Ray Tonkin is seeking the death penalty against Frein, 33, who allegedly opened fire from a wooded area across the street from the Blooming Grove barracks in northeastern Pennsylvania on September 12, 2014. Cpl.
Defense lawyer Michael Weinstein did not call any witnesses and in a 10-minute closing argument told jurors what happened that night was a "tragedy of monumental proportions".
As the verdict was read, Frein was standing with his head down, hands folded in front of him.
"Got a shot and took it", Tonkin said, reading from the notebook. He wrote a letter to his parents while on the run in which he talked about sparking a revolution.
The search involved 1,000 law enforcement officials and spanned more than 300 square miles of the Pocono mountain wilderness in northeastern Pennsylvania.
He faces a potential death sentence. Pennsylvania last used the death penalty in 1999.
