The identities of the other victims were not officially released, but they were identified by friends, family members and local authorities:
-- John Altobelli, 56, was the head baseball coach of Orange Coast College in Costa Mesa, serving in that role for 27 years, the school said in a news release.
-- Family members confirmed Altobelli’s wife Keri and their 13-year-old daughter Alyssa also perished in the crash. Alyssa was a teammate of Gianna Bryant’s.
-- Christina Mauser was an assistant basketball coach for the Mamba Academy. Her husband confirmed her death in a Facebook post.
-- Orange County resident Sarah Chester. 45, and her 13-year-old daughter Payton passed away in the crash, friends and family told KABC. Payton attended Harbor Elementary School in Newport Beach and was teammates with Gianna Bryant and Alyssa Altobelli.
-- Helicopter pilot Ara Zobayan was Kobe Bryant’s private pilot, a flight student told the Los Angeles Times. Zobayan was an instrument-rated pilot -- meaning he was qualified to fly in foggy and cloudy conditions -- with more than 1,000 hours piloting the craft, it was reported.
The helicopter took off from John Wayne Airport in Orange County at 9:06 a.m., records show. The crash occurred in foggy conditions, which prompted the Los Angeles Police Department to ground its helicopter fleet, the nation's largest such fleet. LAPD chopper flights began in the afternoon.
All of the victims on the flight were reportedly from Orange County; they were reportedly on their way to the Mamba Sports Academy in Thousand Oaks for a basketball tournament.
