Nathan Millard, a Georgia man who went missing in Baton Rouge the evening of Feb. 23 after attending an LSU basketball game, had "[n]o evidence of internal or external trauma" after his death, according to the East Baton Rouge Parish coroner.

Millard, 42, was found dead and rolled up in a carpet in a vacant lot Monday morning off Scenic Highway in Baton Rouge, about a seven-minute drive from where he was last seen Feb. 23 at Happy's Irish Pub downtown Baton Rouge.

"Final autopsy results pending further studies including toxicology testing. Cause of Death and Manner of Death are pending completion of the final autopsy report," the preliminary report, released Tuesday afternoon, states.

Investigators reportedly told Millard's family that he likely died of an accidental overdose with other people who attempted to hide his body, according to WAFB.

The married father of five and director at a construction firm had been in town to meet with a client at the LSU game and then headed to Happy's afterward. Around 11:30 p.m., Millard left Happy's to go back to his hotel room but never made it back, Millard's high school friend, Matt Still, previously told Fox News Digital.

Happy's is about a two-minute walk from the Courtyard Marriott hotel where Millard was staying.
