Telemachus Orfanos was a U.S. Navy veteran with a thick beard, an easy smile and a gladiator helmet tattoo.
Photos on Orfanos Facebook page show the Eagle Scout with friends at ballgames or at work. Some photos are embellished with patriotic graphics and another marks the anniversary of the Sept. 11, 2001, terrorist attacks.
Twelve people were killed in the Borderline carnage, including a sheriffs deputy described as a “hero.” The gunman was found inside, dead of an apparently self-inflicted gunshot wound.
