A Pennsylvania state trooper who was injured when a gunman ambushed him and killed another trooper outside a police barracks is conscious and talking for the first time since he underwent surgery, a spokesman said Sunday.
State police spokesman Trooper Tom Kelly said investigators hope to soon interview Trooper Alex Douglass to get additional information on the attack.
The troopers were ambushed around 10:50 p.m. Friday as one of them was leaving the barracks and another was arriving. Cpl. Bryon Dickson of Dunmore was killed.
Kelly said in an emailed statement Sunday that police are getting a large number of tips, and some are "fantastic."
He said they are keeping details of the investigation quiet to preserve the integrity of the leads.
Investigators on Sunday returned to scour the woods across from a state police barracks where the two troopers were ambushed, leaving one fatally shot and another critically wounded.
Troopers also set up a checkpoint near the site where they were stopping motorists to ask if they had seen anything that could help with the case, Kelly said.
The developments come as a nonprofit group offered a $50,000 reward for tips about Friday's deadly assault at the remote post in northeast Pennsylvania.
Reporters saw investigators walk into the dense forest surrounding the barracks in Blooming Grove around noon Sunday, though authorities suggested a day earlier that the suspect had already left the area.
Police said there would be no news conference Sunday.
Dickson, a seven-year veteran, had transferred to the region from the Philadelphia barracks several months ago. Taken to a hospital, Douglass underwent surgery and was in critical but stable condition.
Pennsylvania State Police Commissioner Frank Noonan said the "cowardly attack" was directed at state police and a "very dangerous, armed criminal" eluded quick capture.
"Our troopers were ... shot without warning and really had no chance to defend themselves," Noonan told reporters Saturday afternoon. "It has touched us to the core that such a thing could happen."
Pennsylvania Crime Stoppers, which posted the reward offer, asked anyone with information to call 800-4PA-TIPS
Law enforcement officers from at least three states on Saturday searched state game lands surrounding the barracks in Pike County and beyond.
"There has been an exhaustive search conducted by hundreds of members of law enforcement," said Lt. Colonel George Bivens. "We have canvassed the wooded areas, neighborhoods. We are convinced this individual is no longer in that immediate area."
Police interviewed a man they called a "person of interest," but Noonan said authorities are talking to hundreds of people as part of the investigation. He stressed the man is not a suspect.
The slain trooper was married with two young sons. He was described by friends as devoted to work and family.
"They were a committed couple," Melissa Contorno, a friend of Dickson's wife, told The Times-Tribune. "They were raising a beautiful young family. It's not fair."
