A 41-year-old Lake Charles man convicted April 26 of attempted second-degree murder was sentenced to 15 years in prison without parole Wednesday in state district court.

Dwayne A. Sylvester Sr. was convicted of stabbing Gerald Carter on Feb. 18 at the Easy Aces Casino, 1825 I-10 Service Road. Video surveillance showed Sylvester taking out a knife and stabbing Carter, who was later treated for wounds to his neck and torso.

“I made a mistake,” Sylvester said Wednesday after apologizing to his family and friends.

Sentencing was slated for Monday. But it was delayed to Wednesday after Davis heard a motion that day by defense attorney Emily Wagner for a new trial.

Wagner said Sylvester had been prevented from fully exploring the history between him and Carter and was therefore unable to fully defend himself. Judge Clayton Davis denied the motion.

Prosecutor Hope Buford also filed a bill of information Monday charging Sylvester as a habitual offender. A hearing will be Aug. 24.
