For Immediate Release
U.S. Attorney's Office, Northern District of Texas


On October 5, David Martinez Martinez, 40, was sentenced to two years in federal prison for possession of a firearm by prohibited person. Martinez was previously admitted to the United States on a non-immigrant visa and not allowed to possess a firearm. In October 2019, Martinez was driving a truck down Interstate-45 when law enforcement noticed a defective taillight and pulled the vehicle over. A search was conducted of Martinez’s truck. Law enforcement recovered five firearms hidden in various packages. This case was investigated by the ATF. Assistant U.S. Attorney Melanie Smith prosecuted this case.


On October 5, Robert Riveros was sentenced to 22 years for conspiracy to interfere with commerce by robbery, interference with commerce by robbery, and possessing a firearm in furtherance of crime of violence.  In 2016, Riveros was charged along with four other coconspirators for a string of violent robberies against jewelers. In one instance, Riveros punched through a car window of a jewelry salesman and took a case containing jewelry. The jewelry salesman attempted to enter a co-defendant’s vehicle through the window and to retrieve his case. Riveros and other co-defendants drove to an apartment complex in Irving, where the victim was removed from the vehicle and beaten, which contributed to his death. This case was investigated by the FBI, Dallas Police Department, and the DFW International Airport Department of Public Safety. Assistant U.S. Attorney Keith Robinson is prosecuted this case.


On October 6, Antonio Lule, 26, plead guilty to assaulting, resisting, or impeding certain officers or employees. FBI agents obtained a search warrant for a Dallas residence.  Shortly before SWAT arrived at the residence, FBI agents who had been conducting surveillance that morning arrived and encountered Lule, who began yelling profanity at the agents. When SWAT arrived, agents gave verbal commands to Lule so law enforcement could detain him. Lule initially refused to obey the commands given by agents. As Lule was being detained he intentionally bit an agent. Lule faces up to 1 year years in federal prison for his crimes. This case was investigated by the FBI. Assistant U.S Attorney P.J. Meitl is prosecuting this case.


On October 7, Arturo Calderon, 26, was sentenced to 40 months in federal prison for making a false statement during the purchase of a firearm. Between February 2018 and February 2019, Calderon purchased numerous firearms from licensed vendors. During the purchase of these firearms, Calderon responded falsely to the question on the ATF Form that asks if the buyer is “the actual transferee/buyer of the firearms(s) listed on this form.” Calderon purchased at least 16 firearms that he then gave to an individual who covered the cost of the firearms, and then additionally compensated Calderon. This case was investigated by the ATF. Assistant U.S. Attorneys Jon Bradshaw and Brian McKay prosecuted the case.
