GRETNA - A 19-year-old man abruptly halted his carjacking trial to plead guilty.
Rockeen Jacks was given a 16-year sentence for the crime he admitted committing on Dec. 22, 2015, according to the Jefferson Parish District Attorney's Office.
Jacks made the decision to change his plea after his victim and several deputies testified against him on the stand.
Jacks admitted to using a gun to commit the crime outside of a convenience store in the 6200 block of the West Bank Expressway near Ames Blvd.
The sentence for Jacks included 10 years for the robbery and a five-year sentence enhancement because a gun was used in the crime. There was another year added for an unrelated battery on a corrections officer charge.
The 64-year-old victim testified that he purchased a plate of food inside of the convenience store and was returning to his Nissan Altima when Jacks approached him with a gun beside his leg.
According to testimony, Jacks repeatedly demanded the keys and the victim eventually surrender.
Two days after the incident the victim and a relative spotted the stolen car and called 911.
The sheriff's office said it found Jacks' DNA on a plastic water bottle in the car.
