PHILADELPHIA (KYW Newsradio) — A Massachusetts man was convicted of first-degree murder Tuesday for killing his girlfriend inside her Bucks County home nearly two years ago.
On June 8, 2022, Northampton police responded to a home on the 12000 block of Clark Court for a “report of a suicidal subject.”
Bodycam footage shows the officers knocking on the door and announcing their presence, but no one answering. Shortly after that, gunshots were heard and a 4-year-old girl covered in blood opened the door, telling the officers that her mother, 31-year-old Samantha Rementer, had been killed by her boyfriend, 37-year-old Thadius McGrath, who then shot himself.
Police entered the home and found another younger child sitting in a height chair. They removed both kids from the home and brought them to safety.
Police then discovered Rementer dead on a bedroom floor. They say she had blunt force trauma to her face and an electric cord wrapped around her neck.
McGrath was suffering from self-inflicted gunshot wounds to the face.
Rementer’s daughter later recounted the events leading up to her mother’s murder, saying the two got into an argument before McGrath beat and strangled her to death.
Before McGrath’s trial, he made a phone call from prison to his parents, admitting the killing was premeditated. He said he thought about what he was going to do, then told Rementer he was going to kill her.
“It very, very much is first-degree murder,” he told his father during the call.
McGrath is guilty of first-degree murder, child endangerment, reckless endangerment of another person, and possession of an instrument of crime.
