LAFAYETTE, La. (KPEL) -- A Kaplan man arrested in 2010 for the killing of a Pizza delivery driver is still awaiting trial; however, he has been sentenced to life in prison as an habitual violent offender.

Prosecutors say 36-year-old Aaron Richards will serve the rest of his life behind bars after being convicted of three separate violent crimes.

Prosecutor Alan Haney says Richards' most recent conviction stems from an incident in which he pulled up in a car behind a 19-year-old woman at the Lafayette Buffalo Wild Wings and punched her twice in the face before speeding away.

The other two violent crimes occurred in Vermilion Parish. The first was a second-degree battery conviction in 1997 and the second was a 2007 conviction for aggravated flight from an officer, which is also considered a violent offense, Haney said.

Police say Richards stabbed and killed Timothy Falgout during a robbery attempt while Falgout was delivering pizza to a home on Rue Canard in Lafayette Parish. He has since been in the Lafayette Parish Correctional Center.

Richards' accomplice, 43-year-old Marcus Joseph Feast, is being charged with principal to first degree murder, and he also is still awaiting trial.
