PIKE COUNTY, Penn. — Prosecutors are seeking the death penalty in the case of suspected cop killer Eric Frein.
Frein faces a dozen charges, including terrorism and first-degree murder, in connection with a September ambush outside the state police barracks in Blooming Grove, Pennsylvania.
He is accused of shooting two state troopers, killing Cpl. Bryon Dickson and injuring Trooper Alex T. Douglass, and then leading a small army of law enforcement officers on a weeks-long manhunt in eastern Pennsylvania.

The self-styled survivalist and military buff was captured on October 30 at an abandoned airport.
The manhunt lasted almost seven weeks, and involved as many as 1,000 officers at times. Authorities said the search cost more than $11 million in salaries, travel, equipment, utilities and other expenses.
Prosecutors had previously said they intended to seek the death penalty. They submitted the formal paperwork on Tuesday.
After his arrest, Frein allegedly told investigators that he “wanted to make a change (in government) and that voting was insufficient to do so, because there was no one worth voting for,” according to an affidavit filed in Pike County.
Frein allegedly called the killing of Dickson an “assassination,” the court documents said. The suspect said the shootings were an attempt to bring about a change in government and to “wake up people, because it was all he could do.”
His next court appearance is scheduled for Thursday. Frein is expected to appear by video from jail.
