Los Angeles, January 27: The helicopter crash in Southern California that claimed the lives of nine people, including NBA legend Kobe Bryant and his daughter, is being investigated by local and federal authorities. The helicopter had crashed into a hillside in Calabasas, California on Sunday morning, killing everyone on board.

"It's a logistical nightmare in a sense because the crash site itself is not easily accessible," Los Angeles County Sheriff Alex Villanueva was quoted as saying in a news conference by CNN. He added that the investigation could be a "very extensive process." NBAKobe Bryant Wife and Kids: Know Everything About Late NBA Star’s Family - Partner Vanessa Laine and Daughters Gianna, Bianka, Natalia and Capri.

Villanueva said the sheriff's office is working with the National Transportation Safety Board and the Federal Aviation Administration to check the cause of the crash and have already secured the site, the CNN report said.

The effort to recover the victims' bodies has also begun but could take a couple of days, Los Angeles County Chief Medical Examiner Jonathan Lucas said, "given the terrain and the condition of the site."

"We're doing everything we can to confirm identifications and give closure to the families involved."
