Yea he was big news around here after the shooting. His face was on TV and in the papers a lot. The Newtown, CT dispatcher was also charged for being in this "conspiracy ring" and the police chief announced his retirement not long after charges were brought up although he claims it's not bc of the steroids being sold under his nose (don't really believe that part).
Alot more then what appears on the surface here, and yes someone snitched them out. Supposedly someone sent the "Feds" a "sample" of his product at which point they then had sufficient evidence to set up a "sting operation". What this means is that once the Feds got a tip on this operation and then used illegal means to verify this, they now create a story to make it plausible enough for the prosecution or general public to "believe" that this case just randomly fell into their laps.
