FORT LAUDERDALE, Fla. -

The leader of a violent gang involved in the 2010 killing of a South Florida armored car guard during a robbery could get life in prison following his convictions on several federal charges.

Sentencing is set for July 1 for 41-year-old Terrance Brown. He was convicted last week of federal robbery and firearms charges. The actual shooter in the case pleaded guilty earlier and was sentenced to life in prison.

Authorities say Brown's seven-member gang tried unsuccessfully to rob two other armored cars before the fatal shooting of a Brink's guard at a Bank of America branch in Miramar. One robbery failed because the armored car failed to show up on time and the second plan was aborted when a police car drove into a bank parking lot.
