MILFORD, Pa. (AP) — Onlookers shouted "Are you sorry?" and "Why did you do it?" at the suspect in a fatal ambush on a Pennsylvania state police barracks as troopers led him from his first court appearance Friday following a grueling seven-week manhunt.

Eric Frein, 31, appeared gaunt and battered as he answered yes or no questions and listened as a judge read the criminal complaint detailing the Sept. 12 attack that killed Cpl. Bryon Dickson and critically wounded Trooper Alex Douglass.

Frein did not have a lawyer and was not asked to enter a plea to first-degree murder and other charges. Frein, who appeared to have a bloody gash on his nose and abrasions on his cheek and above his right eye, remains jailed without bail. A preliminary hearing is scheduled for Nov. 12.

Pike County District Attorney Raymond Tonkin, who said he would seek the death penalty, told reporters that Frein's capture Thursday brought a degree of comfort to the region after an "unimaginable loss of unspeakable proportions."

State police said troopers have been interviewing Frein, a survivalist found in an abandoned airplane hangar with high-powered weaponry nearby, but would not disclose details of what he told them or a possible motive.

Frein's capture ended a 48-day search through impenetrable woods and forbidding caves, schools and vacation homes. The dragnet involved hundreds of law enforcement officials fanned out across the Pocono Mountains of northeastern Pennsylvania and cost about $10 million, State Police Lt. Col. George Bivens said.

In the end, Frein surrendered meekly around 6 p.m. Thursday to a team of U.S. marshals who stumbled across him near the hangar some 30 miles from the rural barracks where he allegedly opened fire Sept. 12, killing a trooper and seriously injuring another.

Authorities placed him in Dickson's handcuffs and put him in Dickson's squad car for the ride back to the Blooming Grove barracks.

"He has been stripped of his guns, his bombs, and now his freedom," Sam Rabadi, chief of the Philadelphia office of the Bureau of Alcohol, Tobacco, Firearms and Explosives, said at a late-night news conference.

The quiet takedown of Frein, who kneeled and put his hands up when marshals approached him, ended weeks of tension and turmoil in the area, as authorities at times closed schools, canceled outdoor events and blockaded roads to pursue him. Residents grew weary of hearing helicopters whirring overhead, while small businesses suffered mounting losses and town supervisors canceled a popular Halloween parade.

"It feels good to know there's a guy like this off the streets," said Gregory Kubasek, 19, of Marshalls Creek, who drove to the barracks Thursday night to catch a glimpse of Frein.

State police Commissioner Frank Noonan said Frein was in good health, despite what he described as a "scratch" on his nose that he said was already there when marshals arrested him.

"He looked fairly healthy, healthier than I would've expected," he said.

State police said they didn't know whether Frein, who was unarmed when captured, had been using the hangar as a shelter during his seven weeks on the run, and they wouldn't say what they found there.

"He did not just give up because he was tired," Noonan said. "He gave up because he was caught."

Dickson's family, as well as Douglass and his family, expressed "relief and gratitude" over Frein's arrest, Noonan said.

Police said they linked Frein to the ambush after a man walking his dog discovered his partly submerged SUV three days later in a swamp a few miles from the shooting scene. Inside, investigators found shell casings matching those found at the barracks as well as Frein's driver's license, camouflage face paint, two empty rifle cases and military gear.

Officials, saying Frein was armed and extremely dangerous, had urged residents to be alert and cautious. Using dogs, thermal imaging technology and other tools, law enforcement officials combed miles of forest as they hunted for Frein, whom they called an experienced survivalist at home in the woods. At times, police ordered nearby residents to stay inside or prevented them from returning home.

Trackers found items they believe Frein hid or abandoned in the woods — including soiled diapers, empty packs of Serbian cigarettes, an AK-47-style assault rifle and ammunition, and two pipe bombs that were functional and capable of causing significant damage.

They also discovered a journal, allegedly kept by Frein and found in a bag of trash at a hastily abandoned campsite that offered a chilling account of the ambush and his subsequent escape into the woods. The journal's author described Dickson as falling "still and quiet" after being shot twice.

Authorities said Frein had expressed anti-law enforcement views online and to people who knew him.

Police found a U.S. Army manual called "Sniper Training and Employment" in his bedroom at his parents' house in Candensis, and his father, a retired Army major, called his son an excellent marksman who "doesn't miss," according to a police affidavit. Authorities believe Frein had been planning a confrontation with police for years, citing information they found on a computer used by him.

A man and a woman believed to be Frein's parents, reached separately by telephone on Thursday, declined to comment.

The manhunt had disrupted some plans for trick-or-treating, but Halloween festivities in Barrett Township, in the heart of the search zone, were back on.

"We as a town think the kids have gone through enough," said Ralph Megliola, chairman of the township board of supervisors.

Helen Blackmore, who lives in nearby Cresco, was ready for some normalcy.

"It was very crazy here. The helicopters were out all the time. Nobody was sleeping. Even today they were out," she said. "We're relieved. We're very relieved. We want things to get back to normal."

Frein is charged with first-degree murder and various other offenses, including two counts of possession of weapons of mass destruction filed after police discovered the pipe bombs.

Dickson, at his funeral, was called a devoted husband and father and "impeccable" former Marine who took his work seriously but also enjoyed making wooden toys for his young sons and finding humor in everyday situations.

Douglass was shot in the pelvis and critically injured in the ambush, which took place during a late-night shift change. He remained hospitalized until Oct. 16, when he was discharged to a rehabilitation facility, state police said.

"If you attack troopers, and a civilized society, the Pennsylvania State Police will bring you to justice. Eric Frein is a coward," the Pennsylvania State Troopers Association said in a statement. "Cpl. Bryon K. Dickson II and Trooper Alex T. Douglass are true heroes."

Patrick Moryto, 21, of East Stroudsburg, rushed to the Blooming Grove barracks after he heard Frein had been caught, and got there in time to see him.

Frein was wearing camouflage pants and a dark hooded sweatshirt when he entered the barracks, Moryto said.

Hours later, the former fugitive left in an orange prison jumpsuit.
