MANKATO – A 28-year-old Mankato man has been sentenced to 90 months in prison after pleading guilty Monday to having sex with a 15-year-old girl.

Raymond Schroer (left) will receive credit for the 240 days he has spent in jail since his arrest.

Schroer and 24-year-old Katherine Olson were both arrested last August for the relationship with the girl.

The girl told investigators that she loved both Schroer and Olson and that they gave her “promise rings.”  

Olson was sentenced in early March to 90 months in prison with credit for time served.
