The Jefferson Parish District Attorney’s Office on Feb. 26 charged Jefferson and two other 17-year-olds, Joe Sharp and David Sampson, with resisting an officer by violence, according to records filed in the 24th Judicial District Court in Jefferson Parish. Sharp also pleaded not guilty on Wednesday to resisting an officer by violence. Sampson pleaded not guilty March 19. Jefferson, younger brother of former LSU quarterback Jordan Jefferson, and the other two teens have a pre-trial conference set for April 2. In the incident, Sampson allegedly shouted profanity at sheriff’s detectives near Severn and Veterans Boulevard during a Mardi Gras parade, according to an affidavit of probable cause for Sampson’s arrest. Detective Joshua Collins told Sampson to stop using profane language, but Sampson continued to yell at the detective, the affidavit says. Collins and Sampson scuffled in the middle of the parade route, the affidavit says. Rickey Jefferson and Sharp then intervened and attacked Collins, which allowed Sampson to run away. Collins eventually broke free of Jefferson and Sharp and chased after Sampson, tackled him and placed him in handcuffs, the affidavit says. Jefferson, a Destrehan High School standout, caught 36 passes for 562 yards and five touchdowns as a receiver his senior year. He is expected to work at defensive back this upcoming season.
