Police in Minnesota have arrested a 35-year-old man for allegedly decapitating with a machete a man he believed raped his girlfriend, PEOPLE confirms.

A spokesperson for the Itasca County Sheriff’s Office in Grand Rapids tells PEOPLE Joseph Christen Thoresen is being held on a single murder charge.

Investigators allege Thoresen used a baseball bat to bludgeon David Haiman, a 20-year-old from Hibbing, Minnesota. According to the spokesperson, Thoresen allegedly stabbed Haiman several times before decapitating him.

Police say Thoresen later dumped Haiman’s torso and his head in a nearby wooded area.

Haiman was missing for five days before failing to show for work on Saturday, police say. His remains were found on Sunday.

According to police, Thoresen’s girlfriend told them she became very upset upon learning Haiman would be coming to the couple’s Grand Rapids apartment: She alleged he had sexually assaulted her once, though he was never charged with the crime. She relayed the rape allegation to Thoresen.

When Haiman arrived, the girlfriend allegedly told police he agreed to have her tie him up. Subsequently, she allegedly punched him, breaking his nose, police said. She eventually untied him, and Thoresen allegedly repeatedly punched Haiman.

Thoresen’s girlfriend allegedly told police the couple had been smoking meth prior to Haiman’s arrival, the police spokesperson says.

Thoresen appeared in court on Wednesday but did not enter a plea to the murder charge. It was unclear Thursday if he has hired an attorney who could comment on his behalf. His bail has been set at $2 million, according to his arrest report.
