BLOOMING GROVE, Penn. (PIX11) -- Several roads around the barracks, including parts of Interstate-84 were closed early Saturday as law enforcement officials from across the region searched Pike County for the person who opened fire on two troopers.
Corporal Bryon Dickson was killed in the ambush and trooper Alex Douglass was seriously injured.
Douglass is listed in critical but stable condition after undergoing surgery.
State Police Commissioner Frank Noonan says one trooper was leaving the barracks in Blooming Grove, and another was arriving during a shift change when shots were fired just before 11 p.m., Friday.
"The individual who perpetrated this heinous crime is still at large," said Noonan. "We do not have a description or any real information on their identity, we are covering a number of leads right now."
While Noonan did confirm they brought Jeffrey Hudak in for questioning, he stressed that Hudak is not being named as a suspect.
"We are talking to many people. Just because we brought someone in, does not mean they are a suspect in any way," said Noonan.
The Blooming Grove barracks covers most of Pike County, which runs along the Delaware River and borders New Jersey and New York.
Commissioner Noonan also said in his press conference late Friday night that they do not know of a motive, but that the attack seemed to be directed at state police.
