Heroin Traffickers Sentenced to Lengthy Federal Prison Terms
Defendants Primarily Distributed Black Tar Heroin in the Mid-Cities Area of the Metroplex

May 04 (Fort Worth, TX) – Nine defendants, who pleaded guilty to their respective roles in a heroin trafficking conspiracy, have been sentenced by U.S. District Judge John McBryde to prison terms ranging from 75 to 480 months, announced U.S. Attorney Sarah R. Saldaña of the Northern District of Texas.  One defendant, John David Talamini was sentenced today by Judge McBryde to 135 months’ imprisonment.  The last defendant to be sentenced in the case, William Water Rainey, is scheduled to be sentenced on June 29, 2012.

Defendants sentenced are:

Mario Guerra-Rocha, 340 months
Agusten Diaz, aka “Popeye,” 480 months
Michael Diaz, aka “Darky,” 108 months
Manuel Parada, aka “Pelon,” 79 months
Matthew Christopher Talamini, 110 months
Christopher Paul Sibley, 108 months
Mark Andrew Talamini, 312 months
Timothy Joseph Metzler, 75 months

The investigation began in May 2011 when the Tarrant County Narcotics Unit, Northeast Sector, arrested Mark Talamini for possessing two ounces of black tar heroin.  Following this arrest, investigators with local and federal agencies worked together to identify his drug associates and his heroin supplier, Mario Guerra-Rocha.  The investigation further revealed that Augusten Diaz supplied the heroin to Mario Guerra-Rocha, who in turn supplied the heroin to others.  Investigators learned that all of the defendants were part of a larger organization responsible for distributing heroin in the Mid-Cities area of the Dallas-Fort Worth metroplex. 

The investigation was conducted by the Drug Enforcement Administration, the Tarrant County Narcotics Unit, and the Bedford, Euless, Grapevine, Haltom City, Hurst, North Richland Hills and Watauga Police Departments.

The case was prosecuted by Assistant U.S. Attorney Shawn Smith.
