Probe Under Way Into Kobe Bryant Crash Cause

US investigators are working to determine the causes of the helicopter crash that killed basketball star Kobe Bryant in California on Sunday.

All nine people on board the helicopter died, including Bryant’s 13-year-old daughter, Gianna.

Investigators are expected to focus on the weather conditions, which were foggy, and on any mechanical failures that may have occurred.

Bryant was considered to be one of the greatest players in the game’s history.

He was a five-time NBA champion for his only team, the Los Angeles Lakers, and a double Olympic gold medallist. He retired in April 2016.

Tributes from fans, fellow basketball players and other public figures have been pouring in from around the world while fans congregate at a makeshift memorial for the player in front of the Lakers’ Staples Center in Los Angeles.

The NBA cancelled a game between the Lakers and the Clippers scheduled for the stadium on Tuesday.
