Girlfriend kills boyfriend after seeing his texts to other women, MO cops say

A man was fatally shot in his sleep after his girlfriend discovered text messages he sent to other women, according to Missouri police and news reports.

Now, 23-year-old Madison Rueckert is set to go to prison for decades following the 2022 New Year’s Eve shooting in Marshfield, court records show.

Rueckert told arresting officers she shot her boyfriend in the head as he was sleeping after she found texting conversations between him and other women, according to KOLR.

She called police and confessed to the shooting before surrendering to local authorities, KWTO reported.

Ann Kopp, the mother of the 24-year-old victim, Jonathan Miller, told KY3 the shooting didn’t “make any sense.”

“I couldn’t believe it because she had found messages from him to other women. He hadn’t even cheated on her,” Kopp told the station.

Originally charged with first-degree murder, Rueckert pleaded guilty to an amended charge of second-degree murder, court records show. She also pleaded guilty to armed criminal action.

On April 25, Rueckert was sentenced to 35 years in prison, according to the court records.

Kopp described her son as a family man who “was a hard worker,” according to KOLR.

“Even though he and Madison had only been together since May, (Madison’s) baby was his number one priority, and spending time with that child,” she told the station.

Marshfield is about a 190-mile drive southeast from Kansas City.
