CALEXICO, Calif. (AP) -- A man accused of operating a drug-smuggling tunnel in California has pleaded guilty after being arrested in May.
The 35-year-old spent nearly six years in a Mexico prison for gun trafficking before being arrested in the U.S.
The San Diego Union-Tribune reported Monday that Habib Mujica pleaded guilty to conspiring to finance, construct and use the drug-smuggling tunnel discovered in Calexico six years ago.
Homeland Security Investigations agents discovered the tunnel at a warehouse in 2011.
Mujica says in his plea agreement that he intended to run a business called Baja Bikes as a front to conceal illegal activities.
He faces up to 40 years in prison and up to $750,000 in fines.
