Accused cop killer Eric Frein has been charged with two counts of terrorism.

Prosecutors filed an amended criminal complaint against Frein Thursday, NBC News reported.

Frein, 31, is charged with the murder of Pennsylvania State Police Cpl. Bryon Dickson and wounding Trooper Alex Douglass in a Sept. 12 sniper attack on the state police barracks in Blooming Grove. The self-styled survivalist then disappeared into the woods, leading police on a 48-day manhunt.

Reporters with WXPI and WBRE/WYOU-TV broke the news on Twitter:

Frein allegedly told state police that he shot the troopers because he wanted to make a change in government, and that the murder of police was intended as an "assassination."

Prosecutors also dropped one of two charges of attempted homicide for the shooting of Douglass, according to WNEP.

James Swetz, an attorney for Frein's family, told the Pocono Record that the accused could make an argument to make his statements inadmissible, since they were made without an attorney present. He said police denied him access to an attorney.

"Mr. Frein had a fifth amendment right and a sixth amendment right to have a message delivered to him that counsel had been retained by his family," Swetz told the paper "Moreover, there is a due process right concerning fundamental fairness."

Frein left behind a letter detailing his account of the shooting, which he allegedly planned far in advance. However, it did not list a motive.

Prosecutors have said they plan to seek the death penalty against Frein.
