The search warrant of the residence resulted in the seizure of more MDMA, LSD, marijuana, a suspected marijuana THC oil lab, Xanax, and two firearms. Those apprehended inside the home included 19-year-old Caleb Pattinson, 20-year-old Quinten Casnave, 20-year-old Devin Aucoin, and 51-year-old Melissa Pattinson (the homeowner).

All of the suspects in the vehicle and home were arrested and booked into the St. Tammany Parish Jail.
