The investigation determined that after leaving their residence on Feb. 15, Day and Hartline travelled under false pretense to a residence on Salmen Avenue in Slidell. At which time, the suspects attempted to carjack them with the intent of stealing Days Camaro.
In the process of the carjacking, Day and Hartline were shot.
Sometime thereafter, the bodies were driven in the Camaro to the East Pearl River Boat Launch on Hwy 90 at the state line, where the vehicle and bodies were disposed of in the river.

They were arrested and held in Mississippi as fugitives out of St. Tammany Parish and were transported to the St. Tammany Parish Jail Tuesday, where they were booked on two counts each of LRS 14:30 First Degree Murder. Waveland Police Department and the U.S. Marshals Task Force assisted in apprehending Landry and Savell.
