Accused Pennsylvania Cop Killer Eric Frein Captured

The man who evaded capture for more than six weeks after allegedly killing a Pennsylvania state trooper and wounding another has been arrested.

Eric Frein was taken into custody Thursday, Pennsylvania State Police told CBS News. Details of the arrest were not released.

Frein, 31, is charged with opening fire outside the Blooming Grove state police barracks on Sept. 12, killing Trooper Bryon Dickson and seriously wounding Trooper Alex Douglass. Frein faces first-degree murder and various other offenses, including two counts of possession of weapons of mass destruction.

State police said they believe Frein, a self-taught survivalist, has a hatred of law enforcement and wanted to target police, not the general public. The ambush attack landed Frein on the FBI's most wanted list, and police were authorized to use deadly force.

Multiple sightings of Frein were reported over the course of the 48-day manhunt in the Pocono Mountains. He was always spotted from a distance, with the rugged terrain allowing him to keep officers at bay. Police said he appeared to be treating the manhunt as a game.

Saying Frein was armed and extremely dangerous, officials had closed schools and urged residents to be alert and cautious as officers used dogs, thermal imaging technology and other tools in their search. At times police ordered nearby residents to stay inside or prevented them from returning home.

They pursued countless tips, and closed in on an area around Frein's parents' home in Canadensis after he used his cellphone to try contacting them, and the signal was traced to a location about three miles away.

Trackers found items they believe Frein hid or abandoned in the woods -- including soiled diapers, empty packs of Serbian cigarettes, an AK-47-style assault rifle and ammunition, and two pipe bombs that were functional and capable of causing significant damage. They also discovered a journal, allegedly kept by Frein and found in a bag of trash at a hastily abandoned campsite, that offered a chilling account of the ambush and his subsequent escape into the woods. The journal's author described Dickson as falling "still and quiet" after being shot twice.

Frein allegedly held anti-law enforcement views for many years and expressed them both online and to people who knew him. But the source of his alleged vendetta remains unclear. His criminal record appears limited to a decade-old misdemeanor case involving items stolen from a World War II re-enactors event in upstate New York, for which he spent 109 days in jail.

Police found a U.S. Army manual called "Sniper Training and Employment" in Frein's bedroom at his parents' house, and his father, a retired Army major, told authorities that his son is an excellent marksman who "doesn't miss," according to a police affidavit. Authorities believe he had been planning a confrontation with police for years, citing information they found on a computer used by Frein.

Frein belonged to a military re-enactor's group, playing the part of a Serbian solder. He had a small role in a 2007 movie about a concentration camp survivor and helped with props and historical references on a documentary about World War I.

At his funeral, Dickson was called a devoted husband and father and "impeccable" ex-Marine who took his work seriously but also enjoyed making wooden toys for his young sons and finding humor in everyday situations. Trooper Alex Douglass was shot in the pelvis and critically injured in the ambush, which took place during a late-night shift change.

Douglass remained hospitalized until Oct. 16, when he was discharged to a rehabilitation facility.
