Answered call without looking at caller ID (it was "Illinois 217-735-2128). Caller claimed to be from the Illinois Police Patrolman's Association. Said they wanted a contribution, sent a form with a donation form to IPPA at 47 West Polk Street Chicago, IL 60605-2000.
Not sure if this is a legitimate call...envelope mailed Presorted first class in Dallas-Fort Worth from PSI (whatever that is)!!!!!!
Googled Illinois Police Patrolman's Association and got a similar set of e-mail reports about a number in the 815 area(8152326585). Same MO probably the same scam!!!!

This number called my phone #, we weren't home, no message left by them.

The call came at 3:26PM CDT on Aug. 4. The answering machine picked it up, and they left a short message of heavy breathing and giggling. Sounded like a small child.

I got a call from this number today.  Hang up as soon as the machine picked up.  I see now that the caller is not cool.

They've been calling me, and I finally convinced the guy to take me off his list, supposedly. He was looking for donations for a police association. (I don't remember the exact name) He told me they were running an anti-drunk-driving campaign. If they call again, I'm calling the Illinois Attorney General.
