NBA legend Kobe Bryant, his 13-year-old daughter and seven others were killed in a helicopter crash on a steep hillside in dense morning fog in Southern California on Sunday, his sudden death at age 41 touching off an outpouring of grief for a star whose celebrity transcended basketball.

The chopper went down in Calabasas, about 30 miles (48 kilometers) northwest of downtown Los Angeles. Authorities said that nine people were aboard the helicopter and presumed dead. Bryant, an all-time basketball great who spent his entire 20-year career with the Los Angeles Lakers, was among the victims, a person familiar with the situation told The Associated Press.

Bryant’s 13-year-old daughter Gianna also was killed, a different person familiar with the case said.

Los Angeles County Sheriff Alex Villanueva would not confirm the identities of the victims Sunday afternoon pending official word from the coroner.

“God bless their souls,” Villanueva said at a news conference.

News of the charismatic superstar’s death rocketed around the sports and entertainment worlds, with many taking to Twitter to register their shock, disbelief and anguish.

“Words can’t describe the pain I am feeling. I loved Kobe — he was like a little brother to me,” retired NBA great Michael Jordan said. “We used to talk often, and I will miss those conversations very much. He was a fierce competitor, one of the greats of the game and a creative force.”

NBA players were in tears during pregame warm-ups as crowds chanted “Kobe! Kobe!” Tiger Woods was unaware of the news during his final round at Torrey Pines in San Diego when he started hearing the gallery yell “Do it for Mamba,” referring to Bryant by his nickname.

People were glued to their phones and TV screens all around the world as news of the crash spread and networks broke into programming with live coverage. A visibly shaken LeBron James wiped his eyes with tissues and walked away alone from the Lakers plane that had just landed in Southern California.
