Weight, stress may have factored in death of pepper-sprayed man

Weight and stress could have intensified the dangerous effects of pepper spray state troopers used to subdue a 550-pound Bel Air man who died in police custody, some experts said.

David Matarazzo, 47, stopped breathing and died after being arrested Monday night outside his Bel Air home, where he had stood with a metal chair and a large rock, threatening to kill his wife and three children, police said.
