I know from listening to a police scanner on a regular basis that, often, the police department's business card file is out of date. When a business is broken into (or damaged), they like to be able to contact the owner but they don't always know who the who the owner is.

If they asked you to verify information they already had, it's probably legit.

Returned call to this number. "John Hall" answered and sttaed this is a Dallas Sheriff's office. He asked me if I have a business and the name of the business. He then stated "Thank You" and apparently that was all he wanted. Very odd call. This phone number shows up as a SW bell public telephone number on reverse search.

Possibly calling for donations??

I have no idea who this was. Not going to pay for reverse look up. So posting it here.
