Police reportedly are planning to examine blood found near a chicken coop Saturday to see if it belongs to a man who is suspected of ambushing a Pennsylvania State Police barracks and has eluded capture for more than six weeks.

The owner of the property in Barrett Township, where the blood was found, sent WNEP-TV photos of police collecting samples of the blood that turned up near the chicken coop and on a nearby walking trail.

Joyce Aleckna told the station investigators are going to test the samples in a lab to see if the blood belongs to 31-year-old survivalist Eric Frein, who is accused of opening fire outside the Blooming Grove state police barracks Sept. 12, killing a trooper and seriously wounding another.

Aleckna told WNEP that none of her animals were injured and are locked up behind fences, suggesting there was no plausible explanation for how the blood got there.

Hundreds of cops are searching for Frein in the woods near his parent’s home in Canadensis. Last weekend the search area was expanded after a woman said she saw Frein near Pocono Mountain East High School in Monroe County. Frien attended the school when he was younger. Authorities said a possible motive for the shooting is Frein’s deep hatred of police.

Police have already tested blood found on porches of two homes for a link to Frein. DNA testing confirmed the blood was not his.
