A manhunt is underway for a University of Connecticut student suspected of killing two people and stealing guns and cars in a three-day rampage.“We know that he is armed and dangerous,” Connecticut State Trooper Christine Jeltema said at a Sunday press conference. “Do not approach him.”In the early afternoon, police said suspect Peter Manfredonia, 23, was driving a stolen black Volkswagen Jetta with a sticker paying tribute to victims of the Sandy Hook massacre in his hometown of Newtown. Hours later they said that car had been found near the border of New Jersey and Pennsylvania. The Valley Independent Sentinel reported that there was a woman in the car—the kidnapped girlfriend of one of the murder victims.Police have been looking for Manfredonia since Friday, when he was seen leaving the scene of a brutal assault on two older men.Cynthia DeMers, whose husband, Theodore, was killed, told the Hartford Courant that Manfredonia had been walking down their road in Willington and needed a ride to his motorcycle.“It could have been anybody who offered him a ride,” she told the newspaper. “It could have been any of my neighbors’ husbands. It just happened to be mine.”Minutes after her husband and neighbor left with the suspect, her husband and the other man were found. DeMers, a woodworker, could not be revived, and police said the second victim’s injuries were extremely serious. They did not describe the injuries.DeMers’ niece wrote on Facebook that he was killed in the “most brutal and unthinkable way. A cruel and damaged individual decided to take his life when my uncle extended his help to them.”“He was a gentle, kind, and funny man,” Nicole Wellington wrote of her uncle. “An example of what it looks like to be a good husband and father. Someone who is spoken of highly by his friends and neighbors as being generous and welcoming. It is deeply unfair that he is no longer in this world with us.”It’s believed that on Saturday night, while on the run, Manfredonia broke into a house in Willington and swiped long guns, a pistol, and a car—which was later found abandoned after a crash near Osbornedale State Park in Derby.SWAT teams and K-9 units swarmed the park, as Derby police warned on Facebook: “Residents are asked to remain vigilant as this suspect is considered armed and highly dangerous.”Hours later, police said they believed Manfredonia had escaped the area. Even more chillingly, they said the investigation had determined that his most recent stop was a Derby home where he allegedly killed an acquaintance, 23-year-old Nicholas J. Eisele, stole the getaway Jetta, and apparently abducted Eisele’s girlfriend, who was reportedly not harmed.Manfredonia is 6-foot-3 and 240 pounds, and was last seen wearing a gray T-shirt, gray sweatpants. He played football for Newtown High School, and his Facebook page—which has not been updated since last year—shows he has raised money for Sandy Hook Promise, a nonprofit that fights gun violence.In an August 2019 Facebook post following several mass shootings, Manfredonia wrote: “An irrefutable factor in this plague of violence effecting the nation MUST be attributed extremist views brought about by an environment that promotes toxic masculinity while enabling individuals with a dangerously severe lack of sympathy/remorse to freely acquire firearms. How much more will it take for people to understand SOMETHING in our system isn’t working and action needs to be taken? Remember the victims, not the shooters or their ideology.”UConn confirmed Manfredonia is enrolled in its School of Engineering/School of Business program but said he was not living on campus.Read more at The Daily Beast.Get our top stories in your inbox every day.
