Protective apparel retailer Professional Police Supply Inc has been sued $165,000 by the family of police officer Tony Zeppetella, who was shot dead while wearing a vest sold by the California company.

Zeppetella's wife Jamie Zeppetella claimed her husband would have survived the incident had the garment carried out its performance promise.

Professional Police Supply Inc denies wrongdoing connected to Zeppetella's death.

The vest that Zeppetella wore when he was killed in June 2003 was made by Second Chance Body Armor Inc, which was sued in November 2003 in connection with the death.

Toyobo Co, which made Zylon fiber used in the vest, was also sued.
