A Wisconsin man has been charged with murdering his housemate after an argument about a woman, subsequently attempting to stage the incident as a suicide by placing the gun on the victim.

Dustin Stinson, aged 35, is facing multiple charges, including first-degree intentional homicide, illegal possession of a firearm due to a previous out-of-state felony, and tampering with a GPS device, according to court documents. During a hearing on Wednesday, Stinson entered a plea of not guilty to all charges.

The tragic event unfolded on September 14 at a home located on the 400 block of Lazy Creek Way in Wausau, roughly 150 miles from Madison. The residence belonged to both Stinson and the victim, Jacob Socha, 31. Authorities reported that the two were eating sandwiches together at the time of the incident.

The conversation soon turned to a discussion about a woman, during which Stinson allegedly remarked that if she was in any trouble, he would “hurt some people,” according to a criminal complaint referenced by local news sources like the Wausau Daily Herald. Stinson then retrieved Socha’s firearm from within the house and resumed their conversation. As the discussion grew more intense, the two men reportedly touched foreheads, and Socha expressed his affection for Stinson by saying he loved him and reassured him about the woman’s well-being.

Stinson allegedly recounted that he saw Socha’s body collapse to the floor. He then placed the gun against Socha’s head, and as Socha attempted to push the barrel away, the weapon discharged.

The defendant allegedly said he then placed the gun in Socha’s hand before leaving the house, area CBS affiliate WSAW reported. He is believed to have ripped off an ankle monitor and called a woman to tell her he had killed Socha. She alerted police, and they responded to the home at about 5:35 p.m. that day, finding Socha on the floor in the home with a gun in his hand and a small hole in his temple.

Socha was pronounced dead days later, on Sept. 19. It is unclear whether the woman Stinson reportedly called is the same one about whom he and Socha were talking.

Soon after police found Socha’s body, an officer walking about a mile away saw someone matching Stinson’s description. The man reportedly said his name was “James,” though Stinson later admitted to giving a fake name because he was scared, the complaint stated.

Stinson was arrested and booked into the local jail. According to authorities, at some point, he called the same woman to whom he had divulged his crime, a woman to whom he had reportedly been ordered not to speak. When a corrections officer asked him about this, he reportedly uttered, “I shot my best friend in the head last night!”

When the officer sought clarification, Stinson allegedly repeated himself and held his hand — in the shape of a gun — at his own temple.

The defendant also stated at one point, “I was high,” when law enforcement spoke with him, per WSAW.

An obituary for Socha remembered him as “a vibrant individual who cherished life and the people around him,” adding that he had a fiancee and was “known for his caring, compassionate nature and unique sense of humor.”

Stinson, who is jailed under a $1 million bond, is set to reappear in court for a scheduling conference on Wednesday. He faces life in prison if convicted of his crimes.
