Al Jazeera firmly believes its story is true. Reporter Deborah Davies, who helped lead the report, said the media outlet believes Sly is just changing his tune now.
She said they were led to Sly by several sources who referred to the pharmacy intern as a "doping genius." Then, through six days and more than 20 hours of careful undercover interviews, they were able to get Sly to open up and start dropping his clients' names.
"In the undercover videos, Charlie is being very truthful," Davies said. "He never said a single false statement. He's never bragging. He's never lying. If he doesn't supply a particular athlete, he's very clear. … If he was really someone who just wanted to brag and thought he was just being set up, and Liam (the undercover interviewer) is just a sucker, he could have just said here is a list of all the big stars I work with."
Davies added that Al Jazeera checked the employment dates of Sly at Guyer, and confirmed he was employed in 2011 when Manning was receiving treatment. Dr. Dale Guyer has since said that Sly was an intern for three months in 2013. She said footage of the call will be aired on Monday on the network.
In addition, the publication attempted to contact Sly on Dec. 4 via email and certified letter for additional comments. It also tried to call him before the imposed Dec. 14 deadline. He did not respond until 48 hours before the broadcast of the piece via email and with the YouTube video, she said.
Davies noted that Manning has not refuted that his wife received HGH shipments. What she and Al Jazeera want to know is if she received them and, without prying into her medical history, whether she does not have one of the three conditions that HGH can legally be prescribed for. If she does not, Guyer may have broken the law if they did indeed send her the drugs.
"These are questions that need to be answered," she said.
