The crash on Jan. 26, claimed the lives of the pilot, the Bryants, John Altobelli, 56, baseball coach at Orange Coast College and his wife Keri Altobelli; Alyssa Altobelli, the Altobellis’ daughter and one of Gianna's basketball teammates; Christina Mauser, basketball coach at Harbor Day School, Gigi Bryant’s school; Payton Chester, a middle school student; and Sarah Chester, Payton Chester’s mother.

Both the Federal Aviation Administration and National Transportation Safety Board have investigated the crash, which happened on a foggy Sunday morning on a hillside in Calabasas, California.

Experts have said weather conditions and possible mechanical issues could be at the top of the list as causes of the crash. The fog was severe enough that morning that the Los Angeles Police Department's Air Support Division grounded its helicopters and didn't fly until later in the afternoon, department spokesman Josh Rubenstein said.
