One of three South Florida-based men accused of stealing $4.8 million in gold from a truck along a North Carolina interstate has pleaded guilty.

Court records show Roberto Cabrera faces a maximum of 50 years in prison after pleading guilty Monday to robbery, firearms and other charges. Sentencing is set for June 23 in Miami.

The FBI says Cabrera, co-defendant Adalberto Perez and an unidentified third man used a GPS device in March 2015 to track the gold-laden tractor-trailer heading from Miami to Massachusetts. Investigators say pepper spray was released by remote control to sicken the driver and a passenger before the robbery along Interstate 95 in Wilson County, North Carolina.

The crooks made off with 275 pounds of gold bars and some silver.

Perez has pleaded not guilty.
