WOODVILLE, WI – Authorities in Calumet County have arrested a 22-year-old man accused of fatally shooting his father during a confrontation inside their family home on Friday afternoon.

Ethan James Graverson faces charges of first-degree intentional homicide after law enforcement officers responded to a 911 call at a residence in Woodville just before 1 p.m. Friday. According to court records, Graverson called authorities himself, telling dispatchers that his father was “going crazy and he had to shoot him.” When deputies arrived, they directed Graverson to exit the home and surrender his weapon. He complied and was detained without resistance.

Investigators discovered the victim—whose name has not been publicly released—unresponsive inside a closet, suffering from multiple gunshot wounds to the torso and groin. Five 9mm shell casings were found scattered on the kitchen floor, police said. Paramedics pronounced the man dead at the scene.

The deadly encounter occurred shortly after Graverson returned home from work. Authorities said he reported finding his father drinking in the house. The two men exchanged words, and their conversation quickly escalated into a heated argument. Graverson told detectives that he thought his father was behaving condescendingly, describing the conflict as “just life in general.”

During his interview with law enforcement, Graverson recounted grabbing a handgun from the garage—the same gun he stated he had handled before but never fired at anyone until that day. He described a tense exchange, claiming his father initially urged him to put the weapon down and offered a hug, but when that failed, allegedly challenged him to “fight man to man.” Graverson admitted to firing at his father, explaining he discharged the weapon several times after his father moved toward him.

Court documents indicate Graverson gave investigators an imprecise accounting of the shots fired, estimating he had shot his father “five, six, maybe” times, and later clarifying it was “six to seven maybe, it wasn’t a full mag.”

According to the affidavit, Graverson’s mother returned home from a trip to the store to find police vehicles outside. She told investigators her relationship with her son had changed after a breakup the prior year, which led him to move back in with his parents. She described Graverson as having struggled emotionally, but did not report any recent tension between her husband and son.

When detectives questioned whether there had been ongoing conflicts in the household, Graverson’s mother expressed shock and asked, “Oh my God, did Ethan do something?” She added that no recent arguments had occurred between her husband and son.

While waiting to be interviewed, deputies observed that Graverson remained unemotional, briefly smirking and chuckling in the holding area, according to their report. During the interview, he revealed to detectives that thoughts of killing his father had lingered since his childhood, beginning when he was 10 or 11 years old. Despite these longstanding feelings, he acknowledged his father had often expressed love toward him.

After detectives informed Graverson of his father’s death, records indicate he responded flatly, stating, “I don’t know how to react to that.” Graverson is currently held in Calumet County Jail on a $1 million bond as the investigation continues.
