Toxicology reports filed in federal court show that two University of Mississippi students who died within hours of each other in Oxford last month had the same three substances in their blood: Mitrogynine and the Schedule 1 controlled substances MGM-15 and MGPI.
Aidan Hamilton, 18, and Robert Strang, 20, both died Sept. 21. Investigators say all three substances are found in Smax-Mango Breeze pills that both students had in their possession when they died. The findings were disclosed in a court filing reviewed by Fox News Digital, ahead of the full toxicology report’s public release.
Lafayette County Metro Narcotics said in a September statement that packaging associated with kratom-related products was found at both death scenes. Officers specifically recovered packages of Smax Mango Breeze MGM-15 priced at $39.99, each marked with a black smudge over the first 9, at both locations.
Arrests at Oxford Tobacco Shop
Yahya Mohamed Mosleh, 51, and his 18-year-old son, Islam Mohamed Mosleh, have been arrested on federal drug charges tied to Puffs Vape, Tobacco and Beer Store in Oxford. Investigators say they traced purchases made by Strang and Hamilton to the shop before the students died.
Court documents say agents made a controlled purchase from Yahya Mosleh, during which he allegedly sold a product kept in a locked container — a product the documents say had been banned under local ordinance for more than four years. Agents then obtained a search warrant and searched the store, finding, according to the filing, “the same Smax Mango Breeze MGM-15 – with the exact same packaging, exact same ingredients and exact same price tag, of $39.99 with a smudge on the 9.”
Lab testing confirmed the products contained the Schedule 1 substances MGM-15 and MGPI. Bank records show Strang and Hamilton each made purchases at Puffs on the same date, the court documents state.
“There is also probable cause to believe these drugs caused two overdose deaths in Oxford, Mississippi. The Government proved that there was probable cause that the laboratory-tested drugs taken by the two overdose victims were the same type of drugs that were seized from the Moslehs during a court-authorized search warrant.”
Warning Given After the Deaths
According to the court documents, Yahya Mosleh sold the same product to a confidential informant after Strang and Hamilton had already died, and warned the informant about it at the time of the sale.
“As the purchase was being made, Yahya Mosleh even told the informant that people were dying from similar products and to be careful. He additionally attempted to conceal his sale when other third parties entered the store, only completing it to the informant when those parties had exited.”
A federal judge ordered Yahya Mosleh held pending trial, finding him to be a flight risk with ties to another country, the documents state. Islam Mosleh was ordered released on a $20,000 unsecured bond with conditions including a curfew and location monitoring.
Court documents also say the store’s owner was indicted by a state grand jury in Lafayette County years ago for distribution of a controlled substance, but fled and is believed to be running the store remotely from Egypt.
Fox News Digital said it contacted the U.S. District Court for the Northern District of Mississippi for comment.
