Mauricio Hernandez, 23, was killed by a Las Vegas police officer on March 8, 2011, after a series of violent events that evening. At about 7:34 p.m. Hernandez allegedly approached a man on Stockbridge Street who was taking out the garbage, drew a handgun, chambered a round, and fired multiple times, striking the victim in the lower back and leaving him paralyzed. Investigators did not determine a motive for that initial attack.

Approximately forty minutes later Hernandez entered a tavern on North Nellis Boulevard and, after sitting down and ordering a drink, stood when uniformed Sergeant David Toney arrived. Hernandez drew a semi-automatic handgun, racked the slide and advanced toward the officer pointing the weapon. Sergeant Toney fired five shots; Hernandez retreated to the restroom and died of a gunshot wound. Ballistics linked the gun used in the tavern to the earlier shooting; investigators found no spent casings from Hernandez’s weapon at the scene. An autopsy detected methamphetamine in Hernandez’s system. The Clark County District Attorney’s Office later determined the officer acted in self-defense, and civilian witnesses told investigators they believed the officer had no other choice.

Did anyone in the Las Vegas area witness Hernandez earlier that evening or know why he might have targeted the first victim?
