A funeral Mass will be held Tuesday for a Salt Lake man who was killed in Phoenix when a security guard's gun accidentally discharged and hit him in the chest.

David Orin French, 40, was apparently shot by an 18-year-old security guard who greeted French as he was checking into a north Phoenix campground Wednesday. The gun was somehow knocked out of a holster and accidentally discharged as it hit the ground, Phoenix police told the Arizona Republic.The newspaper said the guard, Corwin Maurer, attempted to perform cardiopulmonary resuscitation on French after the shooting. French was taken to a nearby hospital, where he was pronounced dead about 40 minutes later.
