Shane Tyler Carrell is being held in the Ada County Jail on a charge of felony lewd conduct after Ada County prosecutors say he had illegal sexual contact with a 13-year-old girl Saturday.

Arrest records show the 18-year-old Carrell was originally charged with three counts of lewd conduct and one count of battery to commit a felony when he was booked into the jail just after midnight Sunday. But those charges were withdrawn when Meridian Police later determined several of the crimes Carrell was accused of occurred before he turned 18, meaning he would have to be charged in juvenile court.

That led Ada County prosecutors to drop those charges Monday morning and refile a single felony lewd conduct charge, saying they have evidence Carrell had illegal sexual contact with the girl Saturday. Prosecutors say other charges are possible in juvenile court, where they could ask a judge to waive those into adult court. That has not yet happened.

Prosecutors said Monday the girl told police Carrell had illegal sexual contact with her for the first time in 2008, when she was in sixth grade, and that Carrell tried at least two more times after that before Saturday's incident, according to court records.

Police began their investigation of Carrell after being contacted by the victim around 8 p.m. Sunday, Meridian Police Chief Tracy Basterrechea said.

Police met with the girl and later talked to Carrell, gathering enough evidence to arrest and book him into the jail just before 12:30 a.m. Monday, Basterrechea said.

Police say the girl is known to Carrell and the illegal sexual contact occurred at a Meridian area home.

Bond for Carrell was set at $100,000 Monday during his initial court appearance. A preliminary hearing in the case is set for June 25.

The crime of lewd conduct with a minor under the age of 16 is punishable by up to life in prison. Anyone who is convicted of that crime also has to register as a sex offender.
