A Kuna man was arrested Thursday and was charged with six felony counts of lewd conduct with a minor and one felony count sexual exploitation of a child.

Deputies say they arrested 30-year-old Michael A. Decker after they conducted an investigation that found he had illegal sexual contact with a 14-year-old girl at his Kuna apartment multiple times in May and June of 2016.

Deputies began their investigation in late October after being contacted.

Detectives say they found evidence that the girl had run away from home at the time and met Decker after she posted an ad on Craigslist looking for a roommate.

Decker was arrested at his home in the N. Bridge Avenue/W. Main Street neighborhood.

According to Ada County Sheriff's Office, detectives also found explicit images on Decker's phone which led to an exploitation charge.

Decker is set to make his initial court appearance Friday afternoon. The crime of lewd conduct is punishable by up to life in prison.

Detectives are concerned there may be other young female victims and would like anyone who has information about the case to call Det. Zach Hessing at (208) 577- 3790 or send an email to
