WEST PALM BEACH, Fla. — A Florida man has been sentenced to 48 years in prison for the fatal robbery of a Florida Atlantic University student.

The Palm Beach Post reports that 24-year-old Alexander Gillis was sentenced Wednesday. He previously pleaded guilty to second-degree murder.

Prosecutors say Gillis and four others broke into the off-campus apartment of 19-year-old FAU student Nicholas Acosta in December 2015. Police say Gillis shot Acosta twice after ordering him and his girlfriend to the ground.

Donovan Henry was sentenced in January to 35 years in prison after being convicted of second-degree murder. Rodrick Woods and Adonis Gillis have both previously pleaded guilty to second-degree murder for their parts in the robbery and await sentencing. A fifth suspect has not been publicly identified or arrested.
