LAKE COUNTY, IL — A $10 million bail has been issued for a 36-year-old Lake County man accused of sexually assaulting a juvenile family member numerous times over several years, authorities said Monday.

Mcred Valderama, of the 24500 block of West Passavant Avenue in unincorporated Round Lake, is a registered a violent offender, authorities said. Detectives learned of the sexual contact between Valderama and the juvenile family member on Friday and took him into custody at his home that same day.

The girl told a trusted adult who then reported the sex assault to police. Detectives obtained “significant evidence substantiating the allegations,” according to a news release from the Lake County Sheriff’s Office.
