12:24 PST SAN FRANCISCO - -- Police are treating the San Francisco Zoo as a crime scene this afternoon, one day after a 350-pound tiger escaped and fatally mauled a 17-year-old San Jose boy before attacking two other men 300 yards away.
A search of the zoo this morning did not turn up any additional victims of the Christmas Day attack, police said today. Investigators are trying to piece together exactly how the 4-year-old Siberian tiger, named Tatiana, escaped from her enclosure prior to the attack, and are asking anyone who witnessed the escape or the attacks to contact police.
The three victims knew each other, although it's wasn't immediately clear why they were in different areas of the zoo at the time of the attacks, authorities said.
Police officers, along with fire department and zoo personnel, conducted four searches of the zoo grounds since the Tuesday evening attack,
