Trooper Adam Reed said the search area in the Pocono Mountains largely remains the same as the past two days but has moved slightly to the southeast.
Police are constantly following up on information they receive, Reed said. He declined to go into specifics about why the shift occurred or what new information police may have.
The search for 31-year-old Eric Frein entered its 16th day Sunday. Authorities believe they have Frein contained within a 5-square-mile perimeter around his parents' home in Canadensis.
Frein is described by authorities as a survivalist, marksman and war re-enactment enthusiast who planned the attack for years, extensively researching how to avoid police manhunts and experimenting with explosives. Frein has held anti-law enforcement views for many years, police said.
Investigators believe he is armed with at least one high-powered rifle and might have booby-trapped the woods where authorities are looking for him.
