The St. Tammany Parish Sheriff’s Office has arrested a Slidell man in connection with the murder of his 40-year-old cousin.

Shortly before 5 a.m. Sunday, May 30, STPSO deputies were dispatched to the 58000 block of Lynn Road near Slidell in reference to a reported shooting.  The victim, who has been identified by the St. Tammany Parish Coroner’s office as 40-year-old Matthew Cetrone, was transported to a local-area hospital where he subsequently died. 

The investigation revealed that for unknown reasons, the perpetrator, identified as Christopher Aaron Burns (D.O.B. 04/19/1991) exited the residence firing numerous rounds from a firearm.  At some point, the victim went outside to investigate the sound of gunfire and was fatally wounded.

Burns will be booked into the St. Tammany Parish Jail on a single count of Second Degree Murder.

“I am extremely pleased with how quickly my personnel were able to make an arrest in this case,” Sheriff Randy Smith said.  “My prayers go out to the victim’s family.”
