Sheriff: Pearl River friends found dead in river were fatally shot in 'carjacking gone bad'

A St. Tammany Parish grand jury indicted four people Thursday in the kidnapping and shooting deaths of Reagan Elizabeth Day and Dustin Ross Hartline, whose bodies were found submerged in the East Pearl River inside Day's vehicle three weeks after they disappeared.

A fifth man was accused of assisting after the fact.

The grand jury also indicted a Folsom man in the beating death of his 7-month-old son, a spokeswoman for 22nd Judicial District Attorney Warren Montgomery's office said.

Day and Hartline, who disappeared in February, were discovered in Day's Camaro, submerged in the river, in early March. The St. Tammany Parish Sheriff's Office said theft of the vehicle was the initial motive in the crime.

Jason David Landry, 18, of Slidell, was charged with two counts of first-degree murder, two counts of aggravated kidnapping and two counts of conspiracy to commit armed robbery with a firearm.

Brittney Michelle Savell, 26, of Slidell, was charged with two counts of second-degree murder, two counts of aggravated kidnapping and two counts of conspiracy to commit armed robbery with a firearm.

Derrion Joseph Lemoine, 23, of Big Spring, Texas, was charged with two counts of second-degree murder, two counts of aggravated kidnapping, two counts of conspiracy to commit armed robbery with a firearm, obstruction of justice by tampering with evidence, and possession of a firearm or carrying a concealed weapon by a convicted felon.

Steven Lee Olivieri, 27, of Slidell, was charged with first-degree murder, obstruction of justice by tampering with evidence, possession of a firearm or carrying a concealed weapon by a convicted felon, and manufacture or possession of a bomb.

James Keith Mitchell, 30, of Slidell, was charged with being an accessory after the fact and manufacture or possession of a bomb.

In the other case, Corey Michael Nauck, 25, of Folsom, was indicted on first-degree murder in the death of his infant son, Carter, who died Feb. 28, the first homicide of the year in St. Tammany Parish.

Nauck admitted to detectives that he had lost his temper and injured his son because of his crying, according to the Sheriff's Office.
