ST. TAMMANY PARISH -- Autopsies will be conducted this morning to determine how two friends missing from the north shore since last month died.

The bodies of Raegan Day, 20, and Dustin Hartline, 28, were found Monday inside of a car pulled from the water at the Pearl River Boat launch.

Authorities identified the bodies but causes of death were not immediately available. St. Tammany Parish Sheriff Randy Smith, however, said investigators suspect foul play and are investigating the case as a homicide.

Day and Hartline, whom authorities have described as friends, were last seen Feb. 15 in Pearl River on their way to Kenner before heading to a doctor’s appointment in Baton Rouge.

They were in Day’s dark blue 2011 Chevy Camaro when they were last seen. That make and model of car is the one authorities pulled from the water Monday.

Smith, who joined investigators at the boat launch, said detectives have leads on possible suspects.

"It’s not the outcome we wanted for the family and we are just glad that we can bring some closure to the family," Smith said.

For days, family and friends did what they could to find the victims, all while investigators say they did the same.

After several days of authorities and divers investigating ponds and other waterways, a tip came in which led them near the Mississippi/Louisiana state line Monday.

"We've been following leads and tips in the sheriff's office following up on every single one," Smith said.
