Couple left behind blatant clues during Bountiful kidnapping, police say

In 2011, Sweat was found guilty of unlawful acquisition of a credit card, a third-degree felony. As part of his plea deal, four other charges, including theft, were dismissed, according to court records. In that case, Sweat, then 17, stole a minivan in West Valley City and drove it to California and left it with a friend. He also stole the van owner's credit cards and passport. Sweat was convicted in the adult system. He had previously been confined to Youth Corrections for unknown convictions.

He was ordered to serve up to five years at the Utah State Prison for a credit card incident and placed on 36 months' probation. In January 2012, Sweat was booked into jail for a probation violation. His probation was later reinstated, and Sweat was ordered to undergo a mental health evaluation, court records indicate.

Both Sweat and Thornberg were charged with misdemeanor theft of services in December. Sandy police say Thornberg's charges came from not paying for a cab ride.
