A 19-year-old LSU student reported missing during the weekend and a 21-year-old woman not affiliated with the university were the two people found dead at a townhouse near campus, but officials said Tuesday they had not found any signs of foul play in their deaths.  

Max Raymond, 19, and Joy Gentil, 21, were found dead at 3005 Highland Road on Monday afternoon when an employee of the short-term rental entered an apartment that was supposed to have been vacated, police said. East Baton Rouge Coroner Dr. Beau Clark said their autopsies showed signs that they may have overdosed on something, but he could not rule conclusively until the toxicology is complete. He noted there was no internal or external trauma to either of their bodies. 

Toxicology results, which will include the amounts and types of drugs detected in their systems, can take up to a month to complete, Clark said. The autopsies were completed Tuesday afternoon.

Raymond, a freshman in his second semester at LSU, was reported missing on Saturday after a family member had not heard from him in three days, LSU spokesman Ernie Ballard said. He said LSU Police then checked a few locations for Raymond, including his dormitory room, where his roommate said he also had not seen him in days.

A neighbor at the adjacent apartment building on Highland Road said police had come around this weekend looking for a student who was missing, however they did not find him.  

Gentil was not affiliated with the university, Ballard said.

Clark noted that autopsies for both Raymond and Gentil found swelling of the brain and lungs, a sign of a slow loss of oxygen, which is often seen in overdose deaths. However, he said without toxicology results, he cannot yet rule of the official cause or manner of death.
