EAGLE, Idaho — An Eagle teenager has been charged as an adult with five counts of sexual assault, the Ada County Sheriff's Office announced on Tuesday.

Deputies arrested 17-year-old Cory R. Campbell late last month on four felony counts of rape and one felony count of forcible penetration.

According to the sheriff's office, the charges stem from five separate cases of sexual assault on teenage girls.

Detectives began their investigation in March after being contacted by a third party. Officials say their investigation revealed evidence that Campbell forced himself on at least five different teenage girls and had illegal sexual contact with them between September and March.

Most of the assaults occurred at homes or in a truck in the Eagle-North Ada County area neighborhood, the sheriff's office said.

Officials noted that none of the crimes were random, and that Campbell was known to all of the victims.

After interviewing the alleged victims and gathering evidence, detectives sent the case information to Ada County prosecutors who charged Campbell as an adult and issued an arrest warrant for him on May 30.

Each of the five charges has a $250,000 bond. Campbell is currently being held in the Ada County Juvenile Detention Center.

Detectives suspect Campbell may have additional victims and would like anyone who has information to call Detective Cherie Tucker at ‪(208) 577-3744 or send an email to ctucker@adacounty.id.gov.
