A Longview woman was sentenced Monday to 30 years in prison after pleading guilty to murder in the death of a man after a May 2016 robbery.

Kambresha Williams, 24, was sentenced by 124th District Judge Alfonso Charles while being given credit for 1,040 days she spent in Gregg County Jail, according to court staff.

She will have to serve 15 years before being eligible for parole, Charles explained after the sentencing. He said murder is a first-degree felony punishable from five to 99 years and a fine as high as $10,000.

Williams was booked into the Gregg County Jail in August 2016 on a murder warrant and a grand jury indictment on a charge of aggravated robbery in connection with the March 23, 2016, fatal shooting of Devin Newson, 20, of Longview.

Charles later declared Williams incompetent to stand trial, and she was taken to North Texas State Hospital in Vernon for treatment. She was rebooked into Gregg County Jail on Oct. 17 and has been in jail since on $750,000 in bonds.

Williams was the third defendant to be prosecuted for the robbery and murder of Newson. All three were indicted in October 2016 by a grand jury on murder charges.

Brenndrick Kesean Lilly, now 23, of Longview was sentenced in November 2017 to 35 years in prison for the killing of Newson and received a 20-year sentence for aggravated robbery. The sentences were to be served concurrently.

Kentrell Jorail Smith, now 23, of Longview drew a 10-year sentence with deferred adjudication in December 2017 in the robbery that left Newson dead. Deferred adjudication is similar to probation, but if the sentence is successfully completed, the case is dismissed.

Arrest warrants for the three defendants show that what started as a robbery evolved into homicide at a convenience store near Interstate 20.

Then-Deputy District Attorney Chris Botto said during the trial of Lilly in November 2017 that Newson set up a drug deal with someone he trusted, “with a woman he had regular contact with.” He said Lilly, Smith and Williams set up Newson to rob him.

Botto said the trio got Newson to go to his usual selling spot, a Food Fast convenience store on U.S. 259 near Interstate 20, where he was shot in the chest.

Williams said Newson and Lilly struggled over a gun before it was fired, according to the arrest warrant for Lilly. Newson was found dead in a vehicle that had crashed into a metal storage building when a police officer arrived at the scene, according to testimony during Lilly’s trial.
