SAN DIEGO - Genaro Lopez was arraigned in federal court today following his extradition from Mexico Friday in connection with allegations that he moved cocaine and other drugs into the United States via a sophisticated tunnel discovered in 2022.
At the hearing, the defendant entered a not guilty plea to drug trafficking charges. U.S. Magistrate Judge Daniel E. Butcher granted the government's request to hold Lopez without bond on grounds that he posed a serious risk of flight from prosecution.
According to court records, Lopez, who is a United States citizen, was a powerful drug trafficker operating on both sides of the border. Prior to July 2021, Lopez operated from the United States out of a stash house in Chula Vista, until July 9, 2021, when investigators stopped three cars leaving the stash house with drugs and executed a search warrant. Authorities seized 241 kilograms of cocaine, eight guns (including two ghost guns), a bulletproof vest, ammunition, high-capacity magazines, and close to $40,000 in cash.
Lopez was not present at the search; he fled to Mexico after the search and remained a fugitive until his recent arrest in Mexico on March 10 at the request of the United States. Four of Lopez's employees were arrested and charged with drug trafficking crimes and have since pleaded guilty and been sentenced.
The United States also alleges that Lopez used a cross-border tunnel discovered in 2022 to smuggle illegal drugs into the United States. Investigators discovered the tunnel on May 12, 2022, while surveilling a second stash house in National City. Authorities stopped four cars leaving the stash house and during subsequent searches of the house and cars, investigators seized close to 800 kilograms of cocaine, 74.8 kilograms (163 pounds) of methamphetamine, and 1.6 kilograms (3.5 pounds) of fentanyl.

Beneath the warehouse, they discovered a tunnel from Tijuana to a warehouse in Otay Mesa that was estimated to be about 1,744 feet long, 61 feet deep and 4-feet in diameter, with reinforced walls, a rail system, electricity and a ventilation system. Six people were arrested in that case; five have since pleaded guilty and been sentenced while one other fled while awaiting sentencing and remains a fugitive.
Lopez's next court appearance for motion hearing and trial setting is scheduled for August 14 before U.S. District Judge Linda Lopez.
This case is being prosecuted by Assistant U.S. Attorneys Paul Benjamin and Lawrence Casper. The Justice Department's Office of International Affairs worked with law enforcement partners in Mexico to secure the arrest and extradition of Genaro Lopez.
*The charges and allegations contained in an indictment are merely accusations, and the defendants are considered innocent unless and until proven guilty.
