Tannersville, PA…The alleged shooter of two Pennsylvania State Police troopers has been taken into custody, Pennsylvania State Police confirmed today. Eric Matthew Frein, 31, who was added last month to the FBI’s Ten Most Wanted Fugitives list, faces state charges of homicide, homicide of a law enforcement officer, and attempted murder, as well as a federal unlawful flight to avoid prosecution charge. He is considered armed and extremely dangerous.

The shootings occurred on September 12, 2014, when a gunman ambushed the two officers at the Pennsylvania State Police Blooming Grove Barracks in Pike County, Pennsylvania. Corporal Byron Dickson, 38, was fatally shot, and Trooper Alex Douglass, 31, was critically wounded. The subsequent investigation linked Frein to the shootings.

Frein was the 503rd person to appear on the Top Ten list since it was created in 1950. Since then, with Frein’s capture, 473 fugitives have been apprehended or located.
