A Red Wing man is now formally charged with murder after allegedly shooting and killing his girlfriend, prompting a response to the crisis that lasted several hours sunday evening

According to a criminal complaint, Darryl Dion Nixon Jr., 41, called 911 just before 5 p.m. He was crying on the phone and asked police to come to his duplex in the 1000 block of Putnam Avenue in Red Wing. Law enforcement later learned that Nixon was armed and had killed himself, and that a woman inside the home had been shot.

Nixon made remarks about the “missing” woman and at one point went outside and fired a gun into the air before an officer hit him with a less-lethal round and he fell back into the apartment. While the Goodhue County Emergency Response Team was on the scene, officers saw Nixon at various points holding a gun to his head and repeatedly begging police to “shoot me.”

Nixon’s mother appeared as the police tried to get him to come out. According to the complaint, Nixon and his girlfriend had been at her home about 15 minutes before he called his mother saying he had shot his girlfriend. Nixon’s mother said her son suffered from mental health issues and had a history of hallucinations. However, she noted that the couple appeared to be in “good spirits” during their brief visit earlier in the afternoon.

Officers asked to go in to check on Nixon’s girlfriend, but he only told them “she’s dead.” Crisis responders negotiated for about three hours before Nixon put down his gun and went outside to surrender, the complaint states.

After searching the home, investigators say they found Nixon’s girlfriend on the couch with at least 10 gunshot wounds to her chest and abdomen.

Nixon is charged with one count of second-degree murder. If convicted, he faces a maximum sentence of 40 years.

At a hearing Tuesday, a judge set his bail at $1 million with conditions or $2 million without conditions. His next court appearance is scheduled for Monday.
