Myrick Laneaux has been indicted in the 2016 killings of Kristina Quintini and Norris Demetrius “Demet” Mueller, shot to death while their baby was struck by a bullet.
A Hancock county jury has indicted Laneaux on two counts of murder and one count each of aggravated assault and taking a motor vehicle, Chief Assistant District Attorney Crosby Parker said Friday.
Quintini, a former dance team captain for the Southern Miss Dixie Darlings, was 28. Mueller was 29. Their child, a daughter, was six months old at the time.
The couple was found dead July 30, 2016, when police investigating a missing person report went in Quintini’s apartment and found them. Police said the baby, shot in her shoulder, was wrapped in blood-stained towels.
Laneaux is set to enter a plea of guilty or not guilty in a hearing set for Dec. 11 in Hancock County Circuit Court, Parker said.
The indictment alleges Laneaux intentionally shot the couple in Quintini’s home at Bay Pines apartments on Louis Piernas Road. An autopsy revealed Mueller died of a gunshot wound to the head and Quintini died from several gunshot wounds.
The aggravated assault charge involves a bullet that struck 6-month-old Mia Mueller. Laneaux is accused of shooting her “under circumstances manifesting extreme indifference to the value of human life.” The child has recovered from her wound.
Laneaux also was indicted on an auto theft charge alleging he stole a truck belonging to Quintini’s mother.
No motive for the shooting was given in a preliminary hearing in November 2016, when the Sea Coast Echo reported Laneaux shouted “I’m innocent!” as he was being led from the courtroom. After the hearing, Bay St. Louis Municipal Judge Stephen Maggio found probable cause to send the case to a grand jury for possible indictment.
A police detective who testified at the hearing said a woman contacted police the day of the shooting and said Laneaux had come to her house and was frantic, the Sea Coast Echo reported. She said Laneaux had told her, “I shot Demet and Kristina. I didn’t mean to do it. I didn’t mean to do it. It was all an accident.”
She also told police Laneaux had been driving a black pickup that belonged to Quintini’s mother.
Quintini was a well-liked member of the Bay High Steppers and later attended the University of Southern Mississippi, friends told the Sun Herald in a previous report.
Mueller’s family described him as “charismatic, smart and funny,” with a “big personality.” Though he had been in trouble, family said he was trying to turn his life around and had two other daughters from a previous relationship.
