A 22-year-old Lake Crystal man accused of sexually assaulting 2 underage girls on different occasions has pleaded guilty to 2 counts of 3rd-degree criminal sexual conduct. William Marcus Daniel Edwards now faces up to 60 months in prison for having sex with the 13 and 12-year-old girls at his apartment in Lake Crystal and near a playground in Mankato last year. The girls told police that they had resisted his sexual advances. Edwards claims that the girls told him they were 16 at the time. He remains in custody in the Blue Earth County Jail, and his sentencing is set for late March.
