Criminal Aliens Sentenced to Prison

Release Date: 
October 7, 2011

Tucson, Ariz. - Two Mexican nationals apprehended by Tucson Sector Border Patrol agents for attempting to illegally re-enter the U.S. were sentenced to prison last week.

Oscar Mendez-Cisneros, 27, from Puebla, Puebla, México, was sentenced to 36 months in prison for re-entry of an aggravated felon.

The U.S. Attorney's office prosecuted Mendez-Cisneros after he was apprehended Sept. 28, 2011. During processing at the Casa Grande Station, the Integrated Automated Fingerprint Identification System revealed he was convicted in 2002 for first-degree assault and was sentenced to 10 years in prison. Record checks also revealed he was deported from the U.S. after serving his sentence. After initial processing, the Tucson Sector's Prosecution Unit submitted the case to the U.S. Attorney's office. Following his incarceration in federal prison, Mendez-Cisneros will be formally removed from the country.

Jesus Guardado-Rizo, 41, from La Piedad, Michoacán, México, was sentenced to 40 months in prison for re-entry of an aggravated felon.

The U.S. Attorney's office prosecuted Jesus Guardado-Rizo after he was apprehended Oct. 11, 2010. During processing at the Tucson Station, IAFIS revealed Guardado-Rizo was convicted in Yolo County, Calif., in 1990 for assault with intent to commit rape and sentenced to two years in prison. Record checks also indicated Guardado-Rizo was deported from the U.S. through Laredo, Texas, after serving his sentence. After initial processing, the Tucson Sector's Prosecution Unit submitted the case to the U.S. Attorney's office for re-entry of an aggravated felon. Following his incarceration in federal prison, Guardado-Rizo will be formally removed from the country.

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

In January 2011, the Tucson Sector Border Patrol implemented the Consequence Delivery System as an integral component of its enforcement strategy. Under CDS, Mendez-Cisneros and Guardado-Rizo are classified as recidivists with a criminal record. Both men are now banned for life from all legalization processes without a waiver from the U.S. Attorney General. CDS centers on delivering a targeted consequence to illegal immigrants while simultaneously disrupting the smuggling cycle and reducing recidivism rates by ensuring consequences are upheld to the full extent of the law.

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

In February 2011, CBP announced the Joint Field Command-Arizona as an organizational realignment that brings together Tucson and Yuma Border Patrol Sectors and their Air Branches, as well as the Tucson Field Office, under a unified command structure. JFC-AZ integrates CBP's border security, commercial enforcement and trade facilitation missions to more effectively meet the unique challenges faced in Arizona.
