After 2 killed and baby injured, Bay man admits it started with an argument over money

A man who fatally shot a woman and her ex-boyfriend and wounded their baby has admitted he fired shots during an argument over a small amount of money, District Attorney Joel Smith said.

Myrick Curtis Laneaux, 29, pleaded guilty Wednesday on two counts of manslaughter and one count of aggravated assault for the July 30, 2016, shooting at Kristina Quintini’s duplex in Bay Pines apartments.

Police found Quintini in a bedroom and Norris Demetrius Mueller, 29, near the back door. Their 6-month-old daughter was wrapped in a comforter with a bullet lodged in her shoulder; the baby has since recovered.

Quintini died of multiple gunshot wounds and Mueller died of a gunshot wound to the head, a preliminary autopsy showed.

Laneaux, a close friend of the couple, has been ordered to prison in sentences that total 60 years after pleading guilty in Hancock County Circuit Court, Smith said in a news release.

Circuit Judge Christopher Schmidt imposed three consecutive 20-year prison sentences Wednesday and suspended 20 years provided Laneaux completes 20 years of probation with no problems.

Bay St. Louis police found no weapon, DNA or fingerprints at the scene, Smith said.

But witnesses reported they saw Laneaux at Quintini’s apartment earlier that day and said everything seemed normal.

Laneaux later told several people he shot them and why, said Assistant District Attorney Chris Daniel, who prosecuted the case.

One witness told police Laneaux had “frantically” told her he shot the couple after it happened.

Both Mueller and Quintini attended Bay High School, where Quintini was a member of the Bay High Steppers dance team. Quintini had attended the University of Southern Mississippi, where she was a member of the Dixie Darlings dance team and was team captain in 2010.

She had recently broken up with Mueller, known as “Demet,” according to friends and family.

Quintini was working as a bartender at the Knock Knock Lounge in Waveland.

Mueller had two other daughters and was working odd jobs, trying to get his life back together, friends said.

Smith said Laneaux apologized several times to their families during his plea hearing, and he said, “I pray that God will forgive me, and I hope you will find in your hearts the ability to forgive me.”

Laneaux, who has three children, also was accused of stealing a pickup truck belonging to the parents of either Mueller or Quintini.

He shouted, “I’m innocent,” while being led from a courtroom after a preliminary court hearing a month after the killings.
