A man convicted of stealing more than $11 million from the Colorado Department of Revenue with help from a former girlfriend was sentenced to 58 years in prison Thursday in Denver District Court.

Hysear Randell, 42, also was ordered to pay $11,862,398.39 in restitution.

Co-defendant Michelle Cawthra was sentenced earlier to 24 years in prison; Randell's wife, Trudy, is currently on probation.

Earlier this year, a jury convicted Randell on 52 of 54 criminal counts, including violations of the Colorado Organized Crime Control Act, theft by receiving, forgery and conspiracy to commit theft.

Cawthra, 32, was a supervisor at the Department of Revenue, and she testified that she took the money at Randell's urging.

The money was stolen through various methods, including creating false businesses and tax returns.

Cawthra pleaded guilty and was sentenced in February. She must repay $10.8 million to the state. Trudy Randell pleaded guilty to a felony charge of theft by receiving.
