On June 3, 1999, an armed man entered the Albertsons at 3864 West Sahara Avenue in Las Vegas and opened fire in a brief, deadly rampage. Store manager Carlos Chuck Leos, 41, was shot and killed while on duty; three other people also died and an employee was critically wounded but survived by playing dead on the floor.

The attacker, identified as 23-year-old Zane Michael Floyd, arrived that morning armed with a modified shotgun and dressed in Marine Corps camouflage. Earlier he had assaulted a 20-year-old woman at his apartment, then walked to the supermarket and fired seven shells over about seven minutes, moving through the store and shooting several employees and customers.

Police surrounded Floyd when he left the store; after an eight-minute standoff during which he threatened to kill himself, officers persuaded him to surrender and he was taken into custody. What details about that morning do readers remember, or does anyone have information about Carlos Leos and his time at the store?
