Diane Dosso Patisso, 28, had stopped by Erie to pick up her brother and husband, who worked together in the family business, before meeting with her parents for the birthday party.

Erie partner George Gonsalves, 69, anticipated locking up after everyone had left.

In October 2006, a Polk County jury convicted former Erie partner Nelson Serrano of the worst mass murder in Polk County history, and he’s spent the past decade on Florida’s death row for those murders.
