Federal court documents reveal that two University of Mississippi students who died in September had identical Schedule 1 controlled substances in their bloodstreams. Toxicology reports indicate that Aidan Hamilton, 18, and Robert Strang, 20, both tested positive for Mitrogynine, MGM-15, and MGPI. Investigators determined these substances are present in Smax-Mango Breeze pills, which were found in the possession of both students at the time of their deaths on Sept. 21 in Oxford, Mississippi.

Lafayette County Metro Narcotics stated that packaging associated with kratom-related products was discovered at both locations. Specifically, officers found packages of Smax Mango Breeze MGM-15 with price tags reading $39.99, each featuring a black smudge on the first 9. Law enforcement arrested Yahya Mohamed Mosleh, 51, and his son Islam Mohamed Mosleh, 18, on federal drug charges connected to an Oxford tobacco shop named Puffs Vape, Tobacco and Beer Store. Investigators traced purchases made by Strang and Hamilton at the store prior to their deaths.

According to court filings, agents conducted a controlled purchase from Yahya Mosleh, who allegedly sold them a product hidden in a locked container. The document notes the product had been banned by local ordinance for more than four years. A subsequent search of the store revealed the same Smax Mango Breeze MGM-15 product, matching the packaging, ingredients, and price tag with the smudge on the 9. Laboratory testing confirmed the presence of Schedule 1 controlled substances MGM-15 and MGPI.

Bank records for both students show they made purchases at Puffs on the same date. The government asserts probable cause that these specific drugs caused the two overdose deaths. Court documents state that Yahya Mosleh made the sale to a confidential informant after the students' deaths. During the transaction, he allegedly warned the informant that people were dying from similar products and advised caution. The report further details that he attempted to conceal the sale when other customers entered the store, completing the transaction only after they left.

Yahya Mosleh remains in custody pending trial after a federal judge deemed him a flight risk with ties to another country. Islam Mosleh has been released on a $20,000 unsecured bond with conditions including a curfew and location monitoring. The owner of Puffs was previously indicted by a state grand jury in Lafayette County for distribution of a controlled substance but absconded. Investigators believe he is now operating the store remotely from Egypt. Fox News Digital contacted the U.S. District Court for the Northern District of Mississippi for comment.
