Sheriff's deputies located and arrested Sandra Oseguera on Tuesday on suspicion of walking away from a Merced County Jail work program. But they found more than just their suspect.

They said they found evidence of an identity-theft scheme.

Oseguera, 22, of Planada, had been accepted to the sheriff's work-in-lieu-of-jail program, but failed to show up for a week, Deputy Rick Shukri said.

Correctional Sgt. Mike Sofranek said Oseguera was to serve a 300-day sentence for charges from weapons violations to probation violation.

While looking for her, deputies visited a Planada home, and said they made two other arrests and found what appeared to be components of an identity-theft plot.

Shukri said he learned Oseguera was staying at a home in the 9700 block of Mission Avenue in Planada, where deputies found John Mosqueda, 24, who had an arrest warrant from San Bruno. While there, the deputies said, Oseguera and her boyfriend, Victor Gastelum, 22, of Planada, arrived.

Oseguera was arrested for failing to comply with a court order and two warrants for petty theft and failure to appear, Sofranek said.

Deputies arrested Gastelum on a local misdemeanor warrant. Oseguera remained in jail late Wednesday, but a jail official said the two men were no longer in custody.

Deputy John Mussotto, assigned to the Sacramento Valley Hi-Tech Crimes Task Force, was called to the home after deputies found computers, color printers and scanners, and identification not belonging to anyone at the house, Shukri said.

Mussotto said deputies found copies of a credit card, Social Security card, driver's license and a check belonging to a man who lived on the property.

The owner of the identification said he never gave anyone permission to use his personal information, Mussotto said.

The fraud and identity-theft expert said he seized two computers and a hard drive from the residence.
