JACKSONVILLE, Fla. -

A Jacksonville man who was convicted in January on charges of an armed robbery that took place in 2011 has been sentenced to 40 years in prison.

Officials said Quayshaun Heath, 21, was sentenced Thursday afternoon to 40 years in prison with a 10 year minimum mandatory.

Heath was convicted in January on charged of armed robbery and possession of a firearm by a convicted felon.

In July 2011, Heath and his co-defendant, Alfonza Alberta, held up 78-year-old Clyde Tompkins. The Korean War veteran was picking up his mail at his apartment complex when Heath and Alberta approached him at gunpoint.

Officials said Heath took the Tompkins' car keys, $12 in cash, and then took off in Tompkins' car.

Jacksonville police said they spotted the stolen vehicle and arrested Heath and Alberta three hours after the robbery. Officers also found the gun used in the robbery lying in the street near the scene where the two were arrested.

Heath has felony convictions for dealing in stolen property and giving false verification of ownership of pawned items.
