The Utah Department of Corrections is being blamed for a series of jail escapes in a newly released legislative audit.

"The Utah Department of Corrections has not been adequately overseeing the contracts of inmates housed in county jails," the audit said. "Inadequate contract oversight has contributed to some jail escapes and other operational problems."

The audit, ordered by the Utah State Legislature in the aftermath of a series of high-profile jail escapes, said corrections officials should revisit their contracts with county jails and demand security upgrades. Changes are already being made, corrections officials insist.

"We have been negligent over a period of time," Utah Department of Corrections Executive Director Tom Patterson told the Deseret News after a legislative hearing on Wednesday. "This decay has been occurring over several years and is one that has to be rectified."

Because of a bed-space shortage in the prisons at Point of the Mountain and Gunnison, corrections contracts with 21 counties in Utah to house inmates. It's a deal that has been beneficial to both sides, with some counties building bigger jails to bank on state inmates. The Sanpete and Kane County jails are currently working on expanding for state beds.

But over the years, the audit said, corrections brass became lax in their oversight of contracted jails.

"Past department directors have not ensured that the jail contracting program grew in sophistication as the number of inmates in the program also grew," the audit said, accusing corrections of not ensuring that security problems at the jail were corrected.

That became painfully apparent in September 2007, when two convicted killers escaped from the Daggett County Jail. Juan Diaz-Arevalo and Danny Gallegos were on the run for a week before being captured again. The pair pleaded guilty to escape charges in Manila's 8th District Court and were sentenced to prison time. They are also facing federal charges and will go on trial Oct. 27.

For years, Daggett County's jail had security lapses and other problems noted in inspections, but little effort was made to fix the problems. In 2004, three county inmates scaled a perimeter security fence in a minimum security area known as "the Green House," a former sheriff's residence that was used to house about 20 inmates. It was sporadically staffed.

A corrections inspection said no inmates should be housed in the Green House. A 2006 inspection found inmates still living there. In 2007, Gallegos and Diaz-Arevalo escaped by walking through an unlocked and unmonitored door that led to the Green House. They climbed a fence and escaped.
