ALBANY (WBRZ) - Livingston Parish School Board President Malcolm Sibley has a specific reason why he left the scene of a crash where one man died, but he and his attorney are not explaining just yet.

They said they won't do so until Louisiana State Police close their investigation, which could take four to six weeks.

Investigators said early Saturday morning Sibley hit another truck parked in the middle of La. 43 just north of Greensburg. Cody Iasigi, 21, of Liberty, Miss., was injured and later died at the hospital.

State Police will not explain until the investigation is over why the truck was parked in the middle of La. 43, or what Iasigi and two other men were doing.

Sibley hired Sherman Mack as his attorney shortly after his arrest for felony hit and run Sunday morning. Investigators found Sibley not to be at fault in the crash, but he was cited for hit and run before posting a $500 bond and released.

"Had Mr. Sibley stayed at the scene of the crash, investigators believe he would not have been charged with any traffic violations," Sgt. JB Slaton explained. "The hit and run charge has nothing to do with the crash itself."

Mack wouldn't answer what his client was doing during the 30 hours period between the crash and his arrest, why he left the scene of the crash, or when Sibley learned of Iasigi's death. He did say Sibley owns a logging company, and it's common for loggers to gets started early in the morning.

"The goal is for these families to move on and have some type of closure," Mack said. "I can tell you that Mr. Sibley, the actions that he took are understandable. Once we're able to give that statement when the investigation is complete, I think people will understand."

State Police did not test Sibley for drugs or alcohol because too much time had passed since the crash. Sibley's truck remains at the State Police Crime Lab where investigators are rebuilding the scene based on pictures and the damages to his truck.

No additional charges are expected.
