MARRERO, LA (WVUE) - The manner of death for the husband in the murder-suicide that was discovered Sunday in Marrero is suspected to be a drug overdose, according to Jefferson Parish Coroner Dr. Gerry Citanovich.
Citanovich said David Mata, 46, had several self-inflicted stab wounds, none of which was fatal. He said several prescription bottles were found in the home, but would not say what the prescriptions were for.
"What we found on autopsy is that he had several non-lethal, self-inflicted wounds to his arm and his neck but our suspicion is that he probably overdosed as well, you know, my suspicion is going to be that that's going to be the ultimate cause of death," Cvitanovich said.
Police believe Mata stabbed to death his wife, Kelli, and young sons, Caden and Liam, before taking his own life.
"As the father of a little boy, it just breaks my heart," Cvitanovich said.
A memorial now sits in front of the Marerro home.
"The boys both had the covers pulled up in their beds up to about their neck. They each had toys positioned on top of the blanket around them - very sad," Citanovich said. "At autopsy, we found that the wife had both a head injury with a skull fracture along with a single incise wound to her neck."
Cvitanovich said she didn't have any defensive wounds to her body, and he suspects Mata hit before stabbing her.
The Jefferson Parish Sheriff's Office does not yet have a motive for the killings. They said Mata was arrested in 2010 for domestic battery against Kelli Mata, who was his girlfriend at the time. In 2003, Mata was charged with drug possession.
Toxicology results on David Mata are pending.
