Sex Offender Sentenced to More Than 3 Years

Release Date

Tucson, Ariz. - A 56-year-old male from Morelos, Mexico, apprehended by Casa Grande Station Border Patrol agents in December 2011, was sentenced in June to 40 months of confinement.

The U.S. Attorney's Office prosecuted Ruben Olguin-Gutierrez after his apprehension for attempting to illegally re-enter the United States as an aggravated felon after deportation. During processing in December, agents using the Integrated Automated Fingerprint Identification System (IAFIS) learned Olguin-Gutierrez was convicted for felony lewd and lascivious acts on a child under 14 in 2004, out of San Joaquin County, Calif., and sentenced to three years in prison.

Following the Border Patrol's initial processing, the case was submitted to the U.S. Attorney's Office for prosecution. Olguin-Gutierrez will be formally removed from the U.S. following his 40-month incarceration and is now banned for life from any legalization process.

All illegal immigrants apprehended by the Border Patrol undergo criminal history checks using IAFIS. This vital tool accesses criminal records throughout the United States, enabling agents to quickly identify violent criminals and wanted persons.

The Tucson Sector Border Patrol is committed to ensuring America's borders remain safe, and that dangerous individuals are prevented from making it further into the interior of the United States and into our communities.

As part of a targeted enforcement strategy, the Tucson Sector places individuals into impact programs designed to influence their decision not to commit a subsequent illegal entry. One impact program involves individuals with prior criminal convictions being prosecuted in federal court.

Customs and Border Protection welcomes assistance from the community. Citizens can report suspicious activity and remain anonymous by calling the Border Patrol at (877) 872-7435 toll free.

U.S. Customs and Border Protection (CBP) is the unified border agency within the Department of Homeland Security charged with the management, control, and protection of our Nation's borders at and between the official ports of entry. CBP is charged with keeping terrorists and terrorist weapons out of the country while enforcing hundreds of U.S. laws.
