Carlos Javier Gavilanes, 33, was one of six people killed in a mass shooting at an apartment complex in Hialeah, Florida, on July 26, 2013. He was returning from his son’s boxing practice and was shot as he was parking his car; his son witnessed the killing.

The shooter, 42-year-old resident Pedro Vargas, set his own apartment on fire before the attack. After shooting the building manager and the manager’s wife when they approached, Vargas continued firing from his balcony and later entered another unit, killing a family of three. The rampage lasted about eight hours and ended when a SWAT team stormed the apartment, killed Vargas, and rescued two hostages.

Reports say Vargas had expressed longstanding anger and frustration and lived with his elderly mother; neighbors described him as having minimal social contact and pent-up rage. No other arrests have been announced.
