George Gonsalves, 69, was one of four people killed in an execution-style attack at the Erie Manufacturing plant in Bartow, Florida, on December 3, 1997. Co-victims were Frank Dosso, 35; Diane Patisso, 28; and George Patisso Jr., 26. The killings shocked the community and remain one of Polk County’s most notorious mass murders.

Investigators identified former business partner Nelson Iván Serrano as the primary suspect. Serrano had been removed as Erie Manufacturing’s president earlier in 1997 amid financial disputes and accusations of mismanagement. Authorities say Serrano traveled from Atlanta to Orlando using assumed names, rented a car, then drove to Bartow and shot the three men at the plant; Diane Patisso was killed after arriving to pick up her husband and brother. A fingerprint on a parking garage receipt linked to Serrano’s rental car became key evidence that investigators say undermined his alibi.

The case produced an extensive trial with many witnesses and remains contested in some quarters. Does anyone have recollections of Erie Manufacturing, the partners involved, or the events surrounding December 1997 that could add detail to the record?
