A Harvey man will spend six months shy of 50 years in prison after pleading guilty as charged to armed robbery and illegal discharge of a firearm, according to Jefferson Parish District Attorney Paul Connick’s office.

Dernard Harris, 25, admitted he robbed a construction worker in full view of his coworkers at a job site at Manhattan Boulevard and Elton Court the morning of July 3, 2014.

Harris later charged the victim and a co-worker after they tried to follow him, firing a .380-caliber pistol at them.

Harris then ran into a vacant apartment complex in the 1500 block of West Chelsea Road, tossed the pistol into a closet and leapt off a second-floor balcony. Jefferson Parish Sheriff’s Office deputies caught Harris after he forced his way through another apartment and into a clothing business on Manhattan Boulevard.

Jury selection was set to begin Tuesday when Harris pleaded guilty before Judge Stephen Enright of the 24th Judicial District Court and was sentenced as a double offender because of a previous armed robbery conviction.

Assistant District Attorneys Angad Ghai and Sloan Abernathy prosecuted the case.
