Pennsylvania state police say blood reportedly found at two homes in the search area for a suspected police killer are not linked to fugitive Eric Frein.
The 31-year-old Frein has eluded capture for more than a month despite an intense manhunt in the Pocono Mountains.
Police say DNA tests rule out any link to Frein in blood droplets found on a covered porch in the area. And they say the material found on a back door at a second home nearby proved not to be human blood.
Frein is charged with opening fire outside the Blooming Grove state police barracks on Sept. 12, killing one trooper and seriously wounding a second.
Authorities have shifted their primary search after a suspected sighting Friday night near Pocono Mountain East High School in Swiftwater.
