Officials closed a northeastern Pennsylvania school district on Tuesday after police say another person spotted accused cop killer Eric Frein in close range of three schools.

Authorities received two recent reports about sightings of Frein near his old high school, with the most recent on Monday. As a result, classes in the Pocono Mountain School District were canceled shortly after 5 a.m. Tuesday, reports Fox News.

Police launched a massive manhunt for Frein five weeks ago after he was charged with fatally shooting a state trooper and critically injuring another at the Blooming Grove police barracks on Sept. 12. The 31-year-old survivalist then fled into the woods.

In the latest reported sighting, a police officer said that he spotted a man believed to be Frein on Monday outside the Swiftwater Post Office, which is within a mile from a high school, junior high and elementary school.

The officer then "lost visual contact with the man through the woods," said Trooper Tom Kelly Tuesday morning. "A search of the area was conducted but no one was located," he added.

The sighting came three days after a woman said she saw Frein near his alma mater, Pocono Mountain East High School. She said that she was out for a walk near the school when she spotted a man carrying a rifle and with mud on his face.

"He had actually turned towards me and that's where you could tell the mud on his face. You could tell the height he was based on the truck he was standing next to," she told ABC affiliate WPVI in Philadelphia.

"You could clearly tell it was a gun, a rifle with a scope attached to it. It looked as though he was looking for something or looking which way to go. He avoided making eye contact. I had the light shining on his upper half and his face was kind of confusing. This guy was not startled by me," she said.
