MIAMI (AP) - Two men have been convicted in the fatal shooting of a security guard during a robbery at a South Florida mall.

A federal jury in Miami found 25-year-old Emmanuel Maxime guilty Friday of multiple counts related to the December 2008 robbery. A separate jury convicted 26-year-old Dwight Carter last month. Both men face possible life sentences.

Authorities say Carter and Maxine fatally shot and robbed 57-year-old guard Carlos Alvarado, who was picking up cash and checks inside a store at Dadeland Mall. They reportedly made off with $63,000.

Two women who served as lookouts were convicted earlier this year. Erskaneshia Ritchie was sentenced to nearly 25 years in prison, while Nikkia Thomas received 19 1/2 years.

All four were arrested in May 2009.
