SWIFTWATER, Pa. (AP) -Pocono Mountain school district is closed after at least two reported sightings of the suspect in a deadly state police ambush.

Officials in the Pocono Mountain East School District announced the decision to cancel classes shortly after 5 a.m. Tuesday.

In the latest possible sighting, a local law enforcement official reported spotting suspect Eric Frein (freen) near the Swiftwater Post Office on Monday, leading to an intensive police search. The post office is less than a half-mile from a high school, junior high and elementary school campus.

The sighting was three days after a woman said she saw Frein near the high school.

Frein is charged with killing one trooper and wounding a second outside the Blooming Grove barracks on Sept. 12.
