Kobe Bryant, one of the NBA's all-time greatest players and an athlete of global renown, was killed at age 41 on Sunday in a helicopter crash near Los Angeles along with his 13-year-old daughter and seven on board, officials said. Bryant rocketed to fame as an 18-year-old rookie and played 20 years for the Los Angeles Lakers, 18 as an all-star forward, and won five NBA championships. The cause of the crash was unknown, and an investigation by the Federal Aviation Administration and the National Transportation Safety Board could take months.
