KUSA - A man charged with second-degree kidnapping and sexually assaulting a young girl was found guilty Monday morning.

Bret Lee Thompson was arrested several days after kidnapping his 8-year-old victim in Denver on June 2, 2011.

He had pleaded not guilty by reason of insanity to kidnapping and sexual assault charges stemming from the abduction in 2011. Thompson's attorney Natalie Frei says Thompson has multiple personality disorder.

Thompson was arrested in New Jersey. His foster mother was sentenced last year to 60 days in jail after pleading guilty to perjury for misleading authorities over his whereabouts.

Thompson faces a sentence of life in prison.
