BOZEMAN - A Three Forks man is charged with incest and failing to register as a sex offender.
Court documents say Donald Lopez Garza, 40, is accused of repeatedly sexually assaulting two young girls for several years. Their mother also suspects that Garcia used Ambien in an attempt to drug one of the victims.
The mother and girls came forward and reported Garza last year. After an investigation, he was arrested on June 20.
Arresting officers say he is a registered sex offender due to a prior conviction, and was not living at his registered address as required by law.
The state's sex offender registry lists Garza as being convicted in 2002 for sexually assaulting a 13-year-old girl.
In court on Friday, a judge set Garza's bond at $100,000. His next hearing is slated for July 5.
