PRICE TWP. - Search teams are following up on a possible Eric Matthew Frein sighting in the area near a tree nursery on Clarks Road near Snow Hill Road, according to state police spokeswoman Tfc. Connie Devens.

Other teams "are searching in other areas of Price and Barrett townships," Devens said in an email at 6:15 p.m.

State police began swarming the tree nursery shortly after 4:15 p.m. Troopers with dogs were scouting the nursery while others trained rifles at the trees in a perimeter extending west on Clarks Road. State police vehicles, overhead lights flashing and sirens blaring, rushed the nursery.

The activity comes as police continue to hunt for Frein of Canadensis, who is wanted for murdering Cpl. Bryon K. Dickson II and wounding Trooper Alex T. Douglass during an ambush at the Blooming Grove barracks nearly a month ago.

Earlier today patrols seemed relatively light around Frein's 308 Seneca Lane neighborhood, where state poli ce believe the 31-year-old is hiding in the woods.

Roughly 1,000 police officers have spent the majority of a 23-day manhunt for the suspected cop killer in that area.

After the shooting, they believe Frein made his way south to Monroe County and attempted to use his cell phone to call home. No one answered, but police were able to narrow their focus to a roughly 5-square-mile search zone straddling Barrett and Price townships near the Delaware State Forest.

Frein has remained elusive despite increasingly chilly nights and sporadic bursts of rain. State police believe the stress is wearing him down and hope to capitalize on his mistakes.

State police did not expect to address the media at a news conference today, spokesman Trooper Thomas Kelly wrote in an email this morning.
