A Baton Rouge man was convicted Friday of fatally shooting a 29-year-old man and wounding his wife while the couple sat in a car in the driveway of an Evangeline Street home in 2013.

The Glock 22 .40-caliber semiautomatic handgun that Jermaine Ruffen used to kill Anthony Jerard Jones and wound Sherika Ellis on June 20, 2013, was stolen in 2011 from an off-duty New Orleans police officer's car in Baton Rouge.

Sixteen shell casings were found at the shooting scene. Ellis testified that Jones was shot 9 times, and she 13 times.

Another man, Andre Scott, 27, of Baton Rouge, pleaded guilty in 2012 to stealing the New Orleans Police Department-issued gun and was sentenced to six years in prison.

Ruffen, 34, faces a mandatory term of life in prison on the second-degree murder conviction. He also was found guilty of attempted second-degree murder.

State District Judge Richard Anderson will sentence him March 23.

The jury vote was 10-2 on both counts. The panel, which deliberated for about three hours, was not told the gun was previously stolen.

Ellis testified Wednesday that Ruffen is the man she saw pumping bullets into their car that night.

Baton Rouge police officer Wallace Britton, who was in the area of the killing when he heard the barrage of gunfire, testified he encountered Ruffen moments later "hastily walking" near the intersection of McClelland Drive and Byron Street. But Ruffen ran when he tried to question him, the officer said.

Britton testified Ruffen dropped an object to the ground while he chased Ruffen. The gun was found a short time later where the object was discarded, and it was determined that the shell casings were fired from that weapon.

Prosecutors said cocaine and $15,000 in cash were found in the car in which Jones was killed and Ellis was wounded. Ellis said she had saved that money so the couple could move to Texas, but the shooting ended that plan.

Ellis was booked on a cocaine possession charge after her release from the hospital, but the charge was dismissed last year.
