Two Mexican nationals were arrested Wednesday after law enforcement officers raided a drug stash house in Rio Rico, federal officials said.

About 2,500 pounds of marijuana was found in the house along with three firearms.

Jose Luis Dominguez de la Rosa, 46, of Santa Cruz, Sonora, and Paul Chavez-Portillo, 25, of Los Mochis, Sinaloa, were taken into custody by officers with the Santa Cruz County High Intensity Drug Trafficking Area Investigation Task Force, which is led by U.S. Immigration and Customs Enforcement’s Homeland Security Investigations.

They are facing felony charges of possession of marijuana for sale and weapons misconduct, according to a news release from ICE.

Investigators became aware of the stash house after the Santa Cruz County Sheriff’s Office received a telephone tip Tuesday that a residence in Rio Rico was being used as a drug stash house. Task force members began watching the house and observed Dominguez de la Rosa and Chavez-Portillo walking out the back door. When investigators attempted to question them, the pair took off running, but the men were quickly apprehended.

Inside the house, task force members found 2,499 pounds of marijuana stacked in bales, a 9 mm semi-automatic pistol, 9 mm submachine gun, .22-caliber rifle and 57 rounds of ammunition, ICE said.
