GULFPORT -- A Gulfport woman has again been sentenced to life in prison for the murder of her ex-boyfriend's girlfriend.
Twonia Renee Williams, convicted in 2012 for the 2009 murder of Katrina Sargent, received a new trial this week from an appeal to the Mississippi Supreme Court.
A Harrison County jury heard similar testimony this week and deliberated about 70 minutes Thursday on charges of murder, second-degree murder or manslaughter. The jury found Williams, 50, guilty of murder.
Circuit Judge Roger Clark sentenced her after the verdict was read.
Sargent, 30, was shot in the face Dec. 5, 2009, in front of her West Virginia Avenue home, in which her three children were sleeping.
At both trials, Williams testified she was angry and shot Sargent but didn't intend to.
Williams had broken up with her boyfriend of 3½ years, and said she had just paid $2,000 for him to get the title to his pickup truck. He moved in with Sargent. Just before the killing, a friend saw Sargent and Sargent's niece riding in the ex-boyfriend's pickup and told Williams.
Williams called her ex-boyfriend, who turned on the phone's speaker, and told him she was "about to come blow up the house, blow up everybody in there," court papers show. Sargent's niece testified she heard the conversation.
Williams repeatedly called him back but the ex-boyfriend refused to answer and turned off his phone, according to testimony.
Williams testified she drove by the house and saw the front door open up and thought it was her ex-boyfriend coming out to talk to her. Sargent came out instead and told her to leave. Sargent's niece said she saw Williams raise the gun to Sargent's face and pull the trigger.
Gulfport police found the murder weapon, a .357 magnum revolver, in a trash can.
A firearms expert testified that type of gun has a safety mechanism to prevent accidental firing.
Based on Sargent's wound, the gun was 18 to 20 inches from her face when it was fired, said Dr. Paul McGarry, forensic pathologist.
In closing arguments, a defense attorney told the jury the killing was manslaughter -- in this case, a killing in the heat of passion. Manslaughter is punishable by up to 20 years in prison.
Assistant District Attorney Crosby Parker said Williams made the decision to arm herself, go to Sargent's home in the middle of the night, get out of her car, cock the weapon and pull the trigger.
"That is not manslaughter," Parker said. "That is murder."
Williams was first convicted of Sargent's murder Feb. 16, 2012. The Mississippi Supreme Court found the trial court had erred in the wording of a jury instruction and said it could have prejudiced the jury. The high court overturned the conviction and life sentence in April and ordered a new trial.
