The face stares from posters, from video screens, from billboards eyes straight ahead, jaw set, lips a tight line.

By now, everyone knows Eric Matthew Frein, the fugitive accused of the Sept. 12 ambush at the Blooming Grove state police barracks that killed Cpl. Bryon K. Dickson II and wounded Trooper Alex T. Douglass.More than two weeks after the attack, and as the search for Frein methodically plods along in the quasi-wilderness of Monroe County, the 31-year-old suspected killer is still something of an enigma, an elusive man with an elusive past.The seemingly clean-cut, all-American boy who peers out from the FBI's 10 Most Wanted poster is a study in contrasts to the portrait painted by investigators of a self-taught survivalist and skilled marksman with a long-standing grudge against law enforcement and a deadly aim.Little by little, authorities have released additional details about Frein's life, even as friends, family members and classmates speak of a remarkably average guy who simply had an intense interest in military re-enacting and history.While the manhunt continues, many questions remain unanswered for the community, as well as Frein's family."I want this to be all over. At the same time, I don't want my brother to sit and rot in jail," his 18-year-old sister, Tiffany Frein, said. "If they do have enough evidence he did it, he should suffer the consequences."Typical familyBorn in New Jersey on May 3, 1983, Frein is the son of Eugene Michael Frein, a retired Army major, and Deborah Frein, who worked as a dental hygienist.In addition to his sister, Eric Frein has a brother, Michael, 36, of Olyphant. Eric Frein served as best man at Michael and wife Melissa's 2006 wedding.Neither Michael Frein nor his parents responded to requests for interviews. Attempts to reach other relatives of Eric Frein were also unsuccessful.Public records show the Frein family lived in several states over the past several decades, including Indiana, Illinois and New Jersey, before moving to their current home at 308 Seneca Lane in August 1994.The home, purchased for $130,000, sits along a gravel road in the Pocono Outpost development, a quiet, rustic neighborhood where residents are more likely to see deer than people in their yards.Tiffany Frein said her family is much like any other. Everyone gets along for the most part. She had a strong relationship with Eric, despite the difference in their ages."We are a typical brother and sister. We fought and had our moments, but we bonded," she said.He does not have a girlfriend but years ago dated a woman who later became a police officer, she said.One thing she did not share was her brother's fascination with firearms he was "really into guns," she said.It was an interest he had with his father, who told authorities he taught Frein how to shoot. His son, the father told police, was the better marksman and "doesn't miss."As a teenager, Frein excelled in the sport as part of the rifle team at Pocono Mountain High School, where he graduated in 2002.Vincent Cardo of Blakeslee, who was on the rifle team with Frein, said his teammate was big into conspiracy theories, such as the debate over who shot President John F. Kennedy. Other than that, he didn't recall much about him."He was a quiet person who kept to himself," Cardo said.Lied about jobIt is unclear what Frein did immediately after high school, but he later attended East Stroudsburg University first for one semester in 2005 as a history major and then for two semesters six years later as a chemistry major. He also took classes on and off at Northampton Community College, at the main and Monroe County campuses, from 2008 to 2013.He did not earn a degree at either school.His life after college remains shrouded in mystery. He told his parents and others he worked at a major pharmaceutical company and had recently landed a job at a chemical plant in Delaware.His sister said she has since learned that was not true."He told my parents lots of things," she said.Frein is not currently employed, said Trooper Tom Kelly, spokesman for the state police at Wyoming. Investigators believe he told his parents he got the job in Delaware so that he could prepare for the ambush.Investigators have said he bounced from odd job to odd job.At Lewis' Supermarket in Cresco, a store manager confirmed Frein had worked there in the past but refused to answer additional questions.Frein had two separate employment stints with the Boy Scouts of America's Lehigh Valley-based Minsi Trails Council, working as a part-time, seasonal employee in 2005-2006 and 2011-2013, council executive Craig Poland said in an email."He was one of a group of employees who worked at our archery and shooting ranges," Poland said, adding Frein is no longer involved with Scouting and is banned from further participation.Passion re-enactingFrein's real passion, all who know him say, was military simulation, or MilSim. Participants use real or authentic-looking uniforms and weapons to recreate battles.Frein was part of a MilSim group known as the Eastern Wolves, which engaged in re-enactments under a larger, umbrella organization known as the Red Alliance, with an emphasis on Eastern European armies from the Cold War era. Teams take part in Airsoft competitions, which are similar to paintball except the weapons fire multicolored plastic BBs.Frein is pictured repeatedly on the MySpace page of Istocni Vuk, a group that portrays Serbian Army soldiers. He went by the name "Vuchko" and favored an early 1990s, Serbian-style uniform.Law enforcement officials have described the accused gunman as having an obsession with the Serbian military, history and culture.A photograph on Frein's MySpace page, which has since been taken down, depicted him in front of the Church of St. Sava, a Serbian Orthodox church in Belgrade, Serbia.Playing armyHe studied Serbian and Russian languages and claimed to have fought with Serbians in Africa, investigators said. A heavy smoker, he apparently liked Serbian cigarettes; searchers found empty packs of Serbian-produced Drina brand cigarettes during the manhunt.The MilSim community is like any other hobby or enthusiast group friendly, open, welcoming, said Jason Dunbar of Bangor, an Airsoft enthusiast who met Frein at competitions in 2003 and 2004."Think of it as grown-ups 'playing army,' " Dunbar said. "It is mostly kids having fun and living a fantasy of sorts almost like a real-life 'Call of Duty,' just with little plastic BBs."Dunbar said he did not particularly care for Frein, whom he described as having a "smugness" about him.At the same time, Frein displayed no propensity for the kind of violence he's now accused of committing, Dunbar said."He did not stand out as any different from anyone else," he said. "I am a rather cautious person and always look for things in people that make me leery, and other than being a jerk, he didn't give any reason to suspect this."Roman Kamensky of New York City, who is part of the Red Alliance, said in an email he also never saw any behavior that would indicate Frein was violent."I don't remember any anti-government or anti-cops statements," Kamensky said. "Since the incident, I've spoken to Eastern Wolves members. They were just as shocked."FilmsFrein's interest in re-enacting helped him land a nonspeaking role in the 2007 short film, "Lustig," about a World War II concentration camp survivor.He portrayed a German soldier in the 16-minute film and is listed among the cast members on IMDb.com, an online movie database.More recently, his military knowledge led to an appearance in a still-unreleased documentary on the Vietnam War called "Vietnam Appreciation Day."In footage from the film obtained by NBC News, Frein talks about teaching the public about military equipment and how it was used.At one point, Frein addressed the difficulty of searching for re-enactors while on location in the woods of Pennsylvania."We had to find them, and we just walked around for two days straight," he says.New York recordFrein had no record in Pennsylvania aside from a citation in 2012 for driving with an expired inspection sticker.His only other prior involvement with the criminal justice system came in 2005, when police in New York charged him stealing $3,120 worth of clothing from a vendor at a World War II re-enactment. He pleaded guilty in 2006 and was sentenced to time served 109 days.Paperwork associated with his New York conviction was found on Frein's nightstand when police searched his home. Authorities cannot say if that was the catalyst for him to act out on his disdain for police.They are confident that they know this:Sometime the night of Sept. 12, Frein drove his parents' Jeep Cherokee to Pike County and crept into the woods across from the Blooming Grove barracks with a .308-caliber rifle.Like the trained assassins he impersonated in war games, he waited for his targets. This time, the bullets were real.Dickson and Douglass had no chance to defend themselves as the sniper's bullets pierced the night. Dickson, 38, of Dunmore, was struck twice and died at the scene. Douglass, 31, of Olyphant, was hit once in the pelvis.The neat haircut seen on Frein's wanted poster is gone, replaced by a wide, mohawk-style cut associated with warriors, investigators said.
