Attempted Escape Results in Additional
30 Months in Prison for Heroin Trafficker

January 25, 2012

Oklahoma City, Oklahoma – Sanford C. Coats, United States Attorney for the Western District of Oklahoma, announced that SERGIO CONTRERAS-SANCHEZ, 32, from Las Vegas, Nevada, was sentenced by United States District Judge Stephen P. Friot to serve 30 months in federal prison for attempted escape. The 30-month sentence is to be served consecutive to the 235 months Contreras-Sanchez was previously sentenced to serve on August 4, 2011, for conspiracy to possess heroin with intent to distribute.

In a prior case, Contreras-Sanchez pled guilty on January 10, 2011, to conspiracy to possess heroin with intent to distribute. While awaiting his sentencing hearing in that case, court records indicate that he contacted a guard at the Grady County Jail indicating a willingness to pay the guard to assist in his escape. The United States Marshals Service used the guard as an informant to learn of Contreras-Sanchez’s plans to escape after returning from the sentencing hearing. On August 4, 2011, Contreras-Sanchez attended the sentencing hearing on his heroin trafficking case in Oklahoma City federal court where he was sentenced to serve 235 months in prison. After returning to the Grady County Jail, the escape attempt was stopped by the United States Marshals Service and Grady County Jail officials, and Contreras-Sanchez was charged with attempted escape. At no time was Contreras-Sanchez in a non-secure area or at risk of escape.

Contreras-Sanchez was indicted for the attempted escape on September 6, 2011, and pled guilty on November 1, 2011. At the sentencing hearing yesterday, Judge Friot made clear that Contreras-Sanchez’s 30-month sentence was to be served following the completion of the 235-month sentence he received last year for heroin trafficking.

This case was investigated by the United States Marshals Service and the Grady County Sheriff’s Office. The case was prosecuted by Assistant U.S. Attorneys Andre’ B. Caldwell and David P. Petermann.
