An 11-time convicted felon was sentenced to life in prison without parole for the June 2008 robbing and beating of former Oakland Raiders wide receiver Javon Walker.
On Wednesday, Deshawn Lamont Thomas' attorney, Betsy Allen, promised to appeal after Clark County District Court Judge Douglas Smith sentenced Thomas as a habitual criminal.
A jury convicted Thomas, 42, in April after five days of testimony, including an account of the attack from Walker.
Walker, 31, testified he was falling-down drunk when he got into a car with two men he didn't know after a night of partying at a Las Vegas clubs in June of 2008.
Prosecutors say Walker was robbed of tens of thousands of dollars' worth of jewelry, cash and casino chips.
Prosecutor Joshua Tomsheck noted Thomas had six prior felony convictions before a Nevada jury convicted him in April of first-degree kidnapping, robbery, battery, battery with intent to commit a crime, conspiracy to commit robbery and conspiracy to commit kidnapping.
Thomas is also awaiting trial on pandering, kidnapping, child abuse and statutory sexual seduction charges in Las Vegas involving a teenage girl, Tomsheck said.
A co-defendant, Arfat Fadel, 32, pleaded guilty to lesser charges and testified against Thomas in return for a chance at being released from prison in less than 15 years. Fadel, who had no prior criminal history, is due for sentencing next week.
Allen argues that Fadel shaped his story to blame Thomas, and that Walker was so intoxicated he could have lost the jewelry and hurt himself falling down.
Thomas had felony convictions dating back to 1987 in California's Alameda County on charges including cocaine possession, assault with a firearm, being an ex-felon in possession of a firearm and possession of cocaine base for sale.
He was sentenced in April in Las Vegas in another case to five years in Nevada prison for the theft of a tourist's designer watch.
