The gunman led authorities on a 48-day manhunt through the rugged Pocono Mountains before U.S. marshals caught him at an abandoned airplane hangar more than 20 miles from the barracks.
After a two-week trial that presented uncontested evidence of Frein’s guilt, the jury convicted him on all 12 charges, including murder of a law enforcement officer, terrorism and two weapons of mass destruction counts related to small explosive devices he left in the woods while eluding capture.
Frein, 33, showed no emotion as the verdict was read, and he avoided looking at his parents as he was led from the courtroom. The trial moves into a penalty phase Thursday, with the same jury deciding whether he deserves the death penalty or life in prison without parole.
Tonkin said he will be seeking “full justice,” while defense lawyer Bill Ruzzo said he will appeal to jurors to spare Frein’s life.
“We would like to present Eric in the most sympathetic light that we can,” he said. “We can’t make him a holy man, but we’re trying to make him a man.”
The verdict was expected after prosecutors presented more than 500 pieces of evidence tying Frein to the ambush. His DNA was found on the trigger of the murder weapon, and police recovered several handwritten notebook pages at his campsite in which he described the attack and his subsequent escape into the woods in chilling detail, writing how he shot Dickson twice and watched him fall “still and quiet.”
Tonkin, in his closing argument Wednesday, called Frein “a terrorist with murder in his heart, a plan in his mind and a rifle in his hand.”
Frein shot Dickson in the chest and through the shoulders and spine from a distance of 87 yards, waited nearly 90 seconds until Trooper Alex Douglass came to Dickson’s aid and then shot him, too, Tonkin said.
The defense offered no evidence or testimony and conceded the government’s overwhelming case for conviction.
Police linked Frein to the ambush after a man walking his dog discovered his partly submerged SUV three days later in a swamp a few miles from the shooting scene. Inside, investigators found shell casings matching those found at the barracks and Frein’s driver’s license.
The discovery sparked a manhunt that involved 1,000 law enforcement officials and spanned more than 300 square miles. The dragnet shut down schools and roads and hurt businesses in the mountainous region, which leans heavily on tourism. At times, police ordered residents to stay inside or prevented them from returning home as they pursued tips and supposed sightings. Trick or treating was canceled.
Frein spent more than a month hiding out at the hangar, using a laptop and pilfered Wi-Fi to follow news of the search. He also worked on a letter to his parents, writing that “only passing through the crucible of another revolution can get us back the liberties we once had.”
Frein added: “Tension is high at the moment and the time seems right for a spark to ignite a fire in the hearts of men. What I have done has not been done before and it felt like it was worth a try.”
A death sentence would send Frein to death row, but the state has a moratorium on executions under Democratic Gov. Tom Wolf. The state’s last execution was in 1999, and it has executed only three people since the U.S. Supreme Court restored the death penalty in 1976.
Wolf applauded the verdict but didn’t address Frein’s sentence.
“Today justice was served and a brutal murderer will be held accountable for his heinous and cowardly acts against members of the Pennsylvania State Police,” he said in a statement.
