SANTA BARBARA COUNTY, Calif. -

The search continues for an inmate mistakenly released early Friday morning.

Santa Barbara County Sheriff's public information officer, Kelly Hoover, called the mix up "rare", considering about 18,000 inmates are released without problems each year.

Hoover said the problem appears to have been caused by human error and not a procedural error. An internal investigation may lead to changes to prevent something like this form happening again.

A warrant has been issued for Eduardo Guzman Gonzales. The 24-year-old was not eligible for parole. Gonzales was in custody for domestic violence, a parole violation and an immigration hold. Deputies don't think the public is at risk of being harmed by him. Anyone with information is urged to call 911 or the department's anonymous tip line at 805-681-4171.

While deputies were searching for Gonzales over the weekend, a patrol deputy at a gas station caught a another inmate who had walked away from Cottage hospital Sunday. Hoover said the inmate who walked away after a hospital following treatment only had a week left on his sentence for a drug paraphernalia charge.
