Got the same call about the police widow fund. As soon as they said Houston I hung up because I live no where near there. It sounded like it was a responsive recording. Got another call this morning from a different number as well from the same area and didn't answer
Called, but I didn't answer and they left no message. Here is a helpful link to charity scams: https://www.consumer.ftc.gov/articles/0085-fu ... nd-firefighters
