DULUTH, Minn. — A man accused in Monday’s fatal shooting in the Gary-New Duluth neighborhood said his relationship with the victim grew increasingly hostile, according to court records.

Brian Ross Shaw, 34, now of Hibbing, was formally charged in front of St. Louis County District Judge Eric Hylden on Thursday with second-degree felony manslaughter for the fatal shooting of Kevin John Weiss, 35, of Duluth. If convicted, he could face a maximum sentence of 10 years in prison and/or a $20,000 fine.

The criminal complaint against Shaw depicts a situation involving three adults spiraling out of control.

According to the complaint, Weiss began dating the mother of Shaw’s children in May, but she kicked him out of the house Monday. Weiss later returned to collect his belongings and broke a window in the home, according to the woman, who had said she wanted no contact with him. She was in contact with Shaw, who told police that he talked to Weiss and told him he had a shotgun. But he denied making threats.

Shaw told investigators the gun accidentally discharged as he fell after Weiss pushed him, but the medical examiner’s preliminary report found the slug’s trajectory didn’t match that account, according to the complaint.

Weiss was pronounced dead at the scene.

The next hearing for Shaw was set for Jan. 4.
