A Border Patrol canine team from the Indio station alerted to a large tractor-trailer during preprimary inspection at the Highway 86 checkpoint near Salton City at about 8 p.m.[1] The 35-year-old driver was sent to secondary inspection, where an imaging scan found anomalies through the cargo, and agents searching the trailer found wooden crates holding bundles that tested positive for marijuana.[1]

Agents counted more than 1,100 bundles weighing about 28,300 pounds (about 12.8 tonnes), which the agency valued at over $22.6 million.[1][2] The agency called it the largest marijuana seizure in El Centro Sector history and one of the biggest checkpoint seizures nationwide.[1] The checkpoint sits on State Route 86, the main road from Mexicali toward Palm Springs, and the haul topped the amounts taken there in all of 2009 and 2010 combined.[2]

The driver was arrested and turned over to the Drug Enforcement Administration along with the marijuana and the tractor-trailer.[1][2] A DEA spokeswoman called it the largest marijuana seizure on record in Imperial County.[2]
