STAR — A former Eagle High School boys basketball coach was arrested late Wednesday afternoon on suspicion of five felonies, including rape.

Jeff Ranstrom, 32, was arrested on suspicion of one count of rape, sexual battery of a minor aged 16 or 17 years old, sexual exploitation of a minor, and two counts of burglary. He was booked into the Ada County Jail just before 5 p.m. Wednesday.

Police believe Ranstrom had an ongoing sexual relationship with a 17-year-old girl from March until August, according to Patrick Orr, spokesman for the Ada County Sheriff’s Office. Detectives first heard about the relationship last week, Orr wrote in an email, after being contacted by a third party. They believe the sexual contact occurred at homes and other places in Star, Meridian, Eagle and Boise.

Multiple sources told the Idaho Press that Ranstrom resigned from his coaching and teaching positions on Sept. 23.

The abrupt resignation came after Ranstrom made a triumphant return to coaching following the death of his infant son in 2015.

In his two seasons (2017-19), Ranstrom went 20-24. He had just snapped the Mustangs' six-year postseason drought by leading them to the state tournament in March.

Ranstrom played for the Mustangs as well. The 2005 graduate was a three-year starter who earned both All-5A Southern Idaho Conference and All-State honors during his final two seasons. He led Eagle to its first ever state title game in 2004. The Mustangs lost 62-37 to Borah in the championship.

He played college ball at Big Bend Community College in Moses Lake, Washington, and Eastern Oregon University in La Grande, Oregon before coming back to coach at Eagle.

Ranstrom is scheduled to appear in court Thursday.

Detectives would like to speak with anyone who has information about the case, according to Orr. They can email Detective Neil Daigle at or call 208-577-3704.
