Suspected blood found on two enclosed porches in Cresco last week does not belong to suspected cop killer Eric Matthew Frein, state police said Monday.

DNA analysis on one sample tested negative for the 31-year-old fugitive, said state police spokesman Trooper Thomas Kelly, in an e-mail. The other sample was not blood.

"(State police) determined that neither of the two investigations are connected to the Frein search," Kelly wrote.

Frein, of 308 Seneca Lane, Canadensis, is the sole suspect in the Sept. 12 sniper attack at the Blooming Grove state police barracks in Pike County which killed Cpl. Bryon K. Dickson II, 38, of Dunmore, and wounded Trooper Alex T. Douglass, 31, of Olyphant. Frein has been on the run since, and state police believe he is now somewhere around the Swiftwater area, 10 miles south of his home.
