Report: Manning's camp sent private investigators to HGH accuser's house

Prior to a documentary released by Al Jazeera alleging Peyton Manning and other professional athletes had used performance-enhancing drugs, two men hired by the Denver Broncos quarterback's lawyers were sent to the home of a key witness' parents.

According to a Washington Post report, the men were looking for Charlie Sly, the primary source implicating Manning's human growth hormone (HGH) use in the documentary, and one initially identified himself as law enforcement before Sly's parents called 911.

Per the report:

Manning's lawyers launched the private probe shortly after Al Jazeera started contacting athletes who would be named in documentary. They hired investigators to identify, locate and interrogate Sly, and sent a lawyer to examine Peyton and (his wife) Ashley's medical records at the Guyer Institute of Molecular Medicine in Indianapolis.

Manning has steadfastly denied taking HGH or any other performance-enhancing drugs since the allegations surfaced, and Sly recanted his claims the day after his parents' house was visited by Manning's investigators.

While Manning denies ever taking banned substances, he does not deny that the Guyer clinic shipped HGH to his wife, which Sly alleged initially.

“We've never said he (Sly) had everything wrong. We just said what he said about Peyton was wrong," Manning's crisis management consultant Ari Fleischer said. "It's like the saying ... Someone with a little bit of knowledge can be a dangerous thing."
