Police still searching for Piazza killer

Posted: Updated:

Still no arrests in the murder of a Tucson businessman. Tom Piazza was at Chick-fil-A on Oracle when a man pulled out a gun and shot him dead. Piazza was under a state complaint for mortgage fraud. Detectives are wondering -- could the suspect be someone who knew Piazza?

CORRECTION: A correction has been made regarding the complaint against Thomas Piazza.  It was originally reported he was under a state indictment, which is incorrect.  He was under a state complaint.  See the related Thomas Piazza correction for more information.
