Rochester, MN (KROC-AM News) - A Rochester man has been ordered to serve a prison sentence for sexual assault convictions involving juvenile girls, including one case connected to a suicide.

According to court records, 22-year-old David Ray Servin entered guilty pleas in all three cases. He admitted to a second-degree criminal sexual conduct charge stemming from a sexual assault reported by an 11-year-old girl in the fall of 2023. According to the criminal complaint, the child met Servin on social media, and the assault occurred when she accompanied him to McQuillan Park in southeast Rochester to purchase THC vape cartridges.

As part of the investigation, Rochester police executed search warrants at Servin’s home and storage unit, where they discovered more than $7,000 in cash, a handgun reported stolen in the Twin Cities, along with THC and nicotine vape cartridges.

Servin also entered a guilty plea to a third-degree criminal sexual conduct charge involving allegations that he assaulted a 15-year-old Stewartville girl in September 2024. Court documents say the teenager took her own life shortly after Olmsted County investigators visited her home following a report of alleged sexual contact between her and Servin.

The third case stemmed from an investigation launched while Servin was being held in the Olmsted County jail following his arrest in the case involving the 11-year-old girl. The criminal complaint alleged that he was involved in a three-year sexual relationship with a juvenile girl that began when she was 14 years old.

The court document says she was identified as a victim after it was discovered that Servin was using jail-issued tablets to communicate with juvenile girls while in custody. He also admitted to a third-degree criminal sexual conduct charge in that case.

Servin has been sentenced to a total of five years in prison for all three convictions. He was given credit for the 444 days he has already spent in jail.
