A Bonneville County jury convicted Jeffrey Lewis Dunn of three felony counts of lewd conduct with a child under the age of 16 on Friday.
During his trial, which started Tuesday, Bonneville County Deputy Prosecutor Danny Clark said Dunn molested three girls aged 6 to 14 between 2004 and 2011.
The jury deliberated for four hours before delivering its verdict Friday afternoon.
Dunn could face a potential life sentence on each charge.
Dunn also admitted a prior conviction on the same charge and was found guilty on a felony enhancement charge. That felony offense carries a mandatory minimum 15 year sentence.
According to the Idaho Sex Offender Registry, Dunn was convicted in 1996 for lewd conduct with a child under 16 in Bonneville County.
Dunn will appear for sentencing before 7th District Judge Dane Watkins Jr. on Jan. 27.
