On February 16, 2018, the mother of the female victim in this case called the St. Tammany Parish Sheriff’s Office to report her daughter, Raegan Day, missing. Day was last seen the previous day leaving Pearl River with her friend, Dustin Hartline. The Sheriff’s Office initiated an investigation to locate the two.
During the course of the investigation, detectives developed information that Day had been in communication with Brittney Savell, who convinced Day and Hartline to pick her up in a Slidell neighborhood for a potential drug purchase. Once a passenger in the car, she directed them to drive to an abandoned property near a home where she had been staying.
When they arrived, Jason Landry and Derrien Lemoine exited an abandoned mobile home with their faces covered, armed with handguns. They forced the two victims out of the vehicle at gunpoint and directed them to walk down a trail into a wooded area. As they were walking, Landry shot Hartline in the back of the head, killing him. The gunshot startled Lemoine, causing him to accidently discharge his weapon, striking Landry in the foot. Then, Landry shot Day in the back of the head.
Landry, Lemoine, and Savell fled the scene and relocated to a residence where Olivieri resided. They advised their friend Olivieri what had transpired. Olivieri and Lemoine went back to the abandoned property to hide the bodies.
As Olivieri and Lemoine approached the murder scene, they discovered that Day was still alive. According to the police investigation, Olivieri ignored Day’s pleas for help and shot her in the head, killing her. Lemoine and Olivieri then moved both victims’ bodies off of the trail to the edge of the wood line, covered them with debris and fled. Olivieri discarded the .25 caliber handgun he had used to kill Day in a nearby water pit.
Later that night, Lemoine returned to the property and put the victims’ bodies in Day’s Camaro. Olivieri followed him to the East Pearl River boat launch off of Highway 90 near the Louisiana/Mississippi State Line where they dumped the vehicle, along with the victims’ bodies, into the river. Eighteen days later, authorities found the vehicle and the bodies in the East Pearl River.
Assistant District Attorneys Jay Adair and Tiffany Dover prosecuted the case. Lieutenant Larry Hudson with the St. Tammany Police Department Criminal Investigations Division led the investigation.
