Considering that is the common script for that kind of scam, it's purely coincidental. Basically it has just as much bearing if I decided to return to my college party days and received the same call:
"We found 22lbs of cocaine and traces of blood left behind..."
wide eyed "Bruh...we're you at that show last night??? That wasn't mine!"
Also, 22lbs is a LAUGHABLY large amount. That would be in the news and you'd have the FBI and DEA at your door. Trust me, this is coincidence. (95% sure)
