After a report by Al Jazeera in December linked Peyton Manning, the Philadelphia Phillies player Ryan Howard and other top athletes to performance-enhancing drugs, United States antidoping officials set out to investigate those claims with the help of Major League Baseball and the N.F.L.
Among the many leads being pursued, according to an antidoping official with direct knowledge of the case, is one involving a nurse practitioner in Houston who had committed suicide two months before Al Jazeera’s documentary was broadcast. The official requested anonymity because the investigation is confidential.
The United States Anti-Doping Agency has begun looking into the relationship between the nurse practitioner, Karen Lopez-Bartlett, and her fiancé, Charles Sly, the pharmacist at the center of the report, who spoke in detail about providing performance-enhancing drugs to several professional athletes. Ms. Lopez-Bartlett’s possible role highlights the unusual nature of the case.
Ms. Lopez-Bartlett ran a holistic medicine clinic in a building that also houses a compounding pharmacy, where technicians mix ingredients to create personalized medicines to treat conditions including pain, impotency and fatigue. Investigators from the antidoping agency are trying to determine if her prescriptions ended up in the hands of Mr. Sly and any athletes and, if so, whether the medicines contained banned substances.
... according to transcripts of the undercover interviews conducted by Al Jazeera, Mr. Sly told Mr. Collins that Ms. Lopez-Bartlett had written prescriptions for him and that he had had access to her prescription pad. (Mr. Sly did not have the authority to write prescriptions.) Mr. Sly had keys to her clinic in Houston, which he visited with Mr. Collins.
Ms. Lopez-Bartlett had killed herself several days before Mr. Collins began secretly interviewing Mr. Sly, though Mr. Sly did not mention her death during several hours of conversations, according to the transcripts.
Mr. Sly told Mr. Collins that he and Ms. Lopez-Bartlett were engaged, according to the transcripts, but that he had misgivings about marriage because it would be a conflict for a husband or a wife to write prescriptions for a spouse.
“She writes a lot of prescriptions,” Mr. Sly said, according to a recording of the conversation. “In the U.S., since I have all these deals with the pharmacies, that’s a conflict of interest. Big time. And we’re making good, good, good money.”
