Kimisha Williams, sister of American basketball star Kawhi Leonard , has been sentenced to life in prison without the possibility of parole for the murder of an elderly woman in 2019 after robbing her.

This is a new drama in the family of the Los Angeles Clippers star, who won the NBA title twice in 2014 with the San Antonio Spurs and 2019 with the Toronto Raptors, after his father was killed in 2008 at his workplace. The 31-year-old has now signed a $176 million contract with the Clippers in 2022.

US local newspapers reported that Kimisha was convicted of killing an 84-year-old woman in 2019.

The crime took place in a casino in Southern California, where the victim and her 92-year-old husband were present. As she was on her way to the toilet, Williams, 39, and her partner, Candice Tanosil, 42, followed her to steal her bag, which contained about $1,000.

The victim was found lying on the ground with her skull fractured, before being taken to hospital, where she died four days later of her injuries.

Leonard's sister, who was banned in 2015 from entering a casino for allegedly stealing a wallet, denied the facts.
