Irvin told investigators with Charles family that the teen had smoked marijuana and was high on hallucinogens when he left her house, the Lafayette Daily Advertiser reports. She said Charles had fallen asleep and when he was awoken, he became combative and said he was going to harm himself.
A coroner’s report said a witness reportedly saw Charles crawling in culverts behind a school, and quoted autopsy witnesses as saying surveillance video showed him alone near the area where his body was found, the AP reports.
Two autopsies, one for the family and the other for the Iberia Parish Coroner’s Office, found small amounts of alcohol and THC, the active ingredient in marijuana, in his blood, the AP reports.
"The uncertainties about whether this drowning represents an accidental, suicidal, or homicidal death makes an undetermined manner of death most appropriate likely," a forensic pathologist at the Louisiana Forensic Center wrote in an opinion.
The autopsy said in part, “Reportedly he had been at a residence where drugs were consumed including possible marijuana (THC) and psilocybin mushrooms. Reportedly after smoking a substance the decedent passed out and when he awoke he became combative. Reportedly he said he was ‘going to kill himself’.”
