Preliminary autopsy results show Kristina Quintini, 28, died from gunshot wounds and boyfriend Norris Demetrius Mueller, 29, died from a gunshot wound to the head.
Hancock County Coroner Jim Faulk received the preliminary autopsy results Tuesday. Mueller’s body was autopsied Monday in Jackson and the Quinitini autopsy was Tuesday. Both bodies were returned to the Coast on Tuesday, Faulk said.
The provisional autopsy results did not indicate where bullets hit Quintini or how many were fired. The couple’s 6-month-old baby, Mia Mueller, is recovering from a gunshot to the shoulder.
The family was shot some time Saturday at Quintini’s duplex in Bay Pines. A call regarding their welfare sent police to the apartment, where the couple was pronounced dead about 7 p.m.
Bay St. Louis Police Chief Mike De Nardo has released little information about the double homicide. But he said in an email Tuesday afternoon that “we have not stopped on this.”
Both Mueller and Quintini attended Bay High School, where Quintini was a member of the Bay High Steppers dance team. She later attended the University of Southern Mississippi, where she was a member of the Dixie Darlings dance team and a captain in 2010.
Long before her death, Quintini had dealt with the effects of gun violence; her father, brother and cousin died in unrelated shootings.
On Sunday, police arrested Myrick Curtis Laneaux, 26, on a charge of vehicle theft. He’s accused in the theft of a car that belonged to Mueller’s mother.
Laneaux has a long criminal history, with convictions for vehicle theft, drug and larceny charges.
Mueller also has had run-ins with the law, though state Department of Corrections officials had no record of any convictions.
In November 2010, Hancock County investigators arrested him on a charge of aggravated assault. Investigators said at the time Mueller shot someone six times. However, the person he shot did not pursue charges and Mueller was never prosecuted.
He also has been arrested over the years on misdemeanor charges of contempt of court and simple assault.
