DALLAS—Ten defendants who were convicted on federal felony offenses stemming from their roles in a drug distribution and robbery conspiracy have been sentenced, announced John Parker, Acting U.S. Attorney for the Northern District of Texas.

On Thursday, June 25, 2015, Elva Sofia Ibarra, 37, of Dallas, was sentenced to 135 months in federal prison, and the following day, June 26, 2015, Quinton Walker was sentenced to 87 months. Others were sentenced as follows:

Cesar Ibarra, aka “Bling,” 40, of Mansfield, Texas—235 months

Hilberto Ibarra, aka “Gilberto,” 30, of Mansfield, Texas—235 months

Cesar Ibarra, Jr., aka “Chicho,” 22, of Dallas, Texas—eight months

Lauro Reyes-Serrano, aka “Wicho” and “Gordo,” 30, of Dallas—57 months

Nicholas Manriquez, 29, of Dallas, Texas—87 months

Andres Garcia, aka “Mentiras,” 31, of Dallas, Texas—12 months and one day

Victor Anderson, aka “Old School,” 52, of Dallas, Texas—21 months

Mark Anthony Nolasco, 23 of Dallas, Texas and Mansfield, Texas—57 months

Most were arrested in June 2014 following a law enforcement operation conducted by special agents with the Federal Bureau of Investigation and officers with the Dallas Police Department.

According to documents filed in the case, Cesar Ibarra and his brother, Hilberto Ibarra, and their sister, Elva Sofia Ibarra (the Ibarra siblings) conspired with each other and others to commit illegal narcotics-trafficking offenses and criminal offenses in furtherance of their drug-trafficking activities, including the commission or planned commission of burglaries, robberies and other acts of violence. The Ibarra siblings and certain other co-conspirators called themselves the “Goon Squad,” and while Cesar and Hilberto Ibarra led the Goon Squad, the Ibarra siblings involved other family members, including Cesar Ibarra, Jr., in their cocaine, methamphetamine and marijuana trafficking activities.

The Goon Squad targeted individuals known, or believed, to be drug dealers for burglary, robbery or other acts of violence, because those individuals were likely to possess large quantities of illegal narcotics, U.S. currency or firearms, and would not be likely to report any offenses by the Goon Squad. They performed surveillance and reconnaissance on their potential victims. They also attempted to perform similar surveillance on members of law enforcement they believed were investigating their illicit activities by taking photographs and recording vehicle-specific information.
