Toxicology reports cited in federal court documents say two University of Mississippi students had the same three substances in their blood when they died in Oxford on Sept. 21. The substances were mitragynine, MGM-15 and MGPI, which investigators say are found in Smax Mango Breeze pills. The findings emerged before the full toxicology reports were scheduled for public release. Federal authorities have connected the investigation to purchases allegedly made at an Oxford tobacco and vape store.
The case has resulted in federal drug charges against Yahya Mohamed Mosleh and his 18-year-old son, Islam Mohamed Mosleh. Court filings allege that products seized from the store had the same packaging, ingredients and price markings as products associated with the two deaths.

Toxicology findings identify three substances
The court documents identify the deceased students as Aidan Hamilton, 18, and Robert Strang, 20. According to the toxicology information described in the filings, both had mitragynine, MGM-15 and MGPI in their bloodstreams. MGM-15 and MGPI are identified in the documents as Schedule I controlled substances.
The results were disclosed in connection with federal proceedings and before the complete toxicology reports were publicly released. The filings do not replace the final public reports, which are expected to provide additional detail about the examinations and the circumstances of the deaths.
Investigators connect products to two deaths
Investigators say Hamilton and Strang possessed Smax Mango Breeze pills when they died in Oxford on Sept. 21. The documents state that the three substances identified in the students’ blood are found in those products. Packaging associated with kratom-related products was reportedly discovered at both locations.
Officers also found Smax Mango Breeze MGM-15 packages bearing $39.99 price tags and a black smudge over the first nine. Authorities say those markings appeared at both locations and later appeared on products seized during a search of the store. The filings assert there is probable cause to believe the laboratory-tested products were the same type of drugs seized from the defendants.
There is probable cause to believe these drugs caused two overdose deaths in Oxford, Mississippi.
That statement is an allegation presented in the federal court documents, not a final finding at trial.
Federal case focuses on Oxford tobacco store
The investigation centers on Puffs Vape, Tobacco and Beer Store in Oxford. Court documents say agents conducted a controlled purchase from Yahya Mohamed Mosleh, allegedly obtaining a product kept in a locked container. The filing says the product had been prohibited by a local ordinance for more than four years.
After the controlled purchase, agents obtained a search warrant and searched the store. They reported finding Smax Mango Breeze MGM-15 products with the same packaging, ingredients and $39.99 price marking described in connection with the students. Laboratory testing determined that the seized products contained MGM-15 and MGPI.
Bank records cited in the filings allegedly show that Hamilton and Strang both made purchases at the store on the same date. The documents also say the store sale occurred after the students’ deaths and that Yahya Mohamed Mosleh warned a confidential informant that people had died from similar products.
Defendants face different custody conditions
Yahya Mohamed Mosleh remains in custody while awaiting trial. A federal judge determined that he presented a flight risk and had ties to another country, according to the court documents.
Islam Mohamed Mosleh is set to be released on a $20,000 unsecured bond. His conditions include a curfew and location monitoring. Both men face federal drug charges related to the investigation, and the allegations remain subject to court proceedings.
The filings further state that the store’s owner had previously been indicted by a Lafayette County, Mississippi, grand jury on a controlled-substance distribution charge. Investigators believe he later left the United States and was operating the store remotely from Egypt.
Full toxicology reports remain pending
The information currently available comes from federal court filings that summarize portions of the toxicology results. The complete reports had not yet been publicly released at the time of the filings, leaving additional questions about the concentrations of the substances and the medical conclusions surrounding the deaths.
The case links the reported toxicology findings, products recovered from the students and products seized from the Oxford store through packaging comparisons, purchase records and laboratory testing. Prosecutors will need to establish their allegations through the federal court process.
