ss427 - the Florissant Police are top notch. Florissant is a small, nice city and they like to keep the crap out. I am sure if you contact them they will be glad to help.
I live very nearby Florissant and even closer to St. Peters.
What is this guy's name??? Post it up - so we know and I can ask around.
Also what is the relation to where you sent the money in St. Peters vs. where the guy lives?
