The sister of NBA star Kawhi Leonard has been charged with murder over the death of an 84-year-old woman whose skull was cracked in a California casino bathroom where she was robbed of about $1,000.

Kimesha Williams, 35, was charged with murder and robbery along with Candace Townswel, 39, for the August 31 attack at the Pechanga Resort Casino in Temecula, according to a report from the Riverside County Sheriff's Office.

Both women were identified by investigators reviewing casino surveillance video as suspects in the beating death of Afaf Anis Assad, 84, of Long Beach, Sergeant Steve Brosche wrote in the report.

Williams, of Moreno Valley, California, was confirmed to be Leonard's sister by her aunt, Denise Woodward, according to the Press-Enterprise.

Williams was confirmed to be Leonard's sister by her aunt, Denise Woodward, also of Moreno Valley. Assad's family members said they also were told by investigators that Williams was Leonard's sister

There is no suggestion that Williams' NBA star brother, who two months ago signed $100 million contract with the Los Angeles Clippers, was in any way involved in the attack.

A spokesman for the Riverside County District Attorney's office did not immediately respond when Dailymail.com reached out.

Assad's family members said they also were told by investigators that Williams was Leonard's sister, and said they hope he can relate to their loss after his father too was murdered.

Mark Leonard died outside his car wash in Compton after he was shot multiple times on January 18, 2008, when the star forward was only 16. The case remains unsolved, reports the Los Angeles Times.

'We know he understands the pain we are experiencing,' Assad's son-in-law Wayne Brown said in a statement released to KCAL9.

Deputies from the Southwest Sheriff's Station said they were called to the casino about 8 a.m. to investigate after Assad was found unconscious in a bathroom. She was transported to a local hospital and admitted with 'serious injuries.'

The victim's skull was broken, reports the Press Enterprise.

'Investigators who had also been closely monitoring Assad's medical status, learned she would likely die from her injuries. The Central Homicide Unit was notified and responded to assist with the investigation,' the sheriff's office wrote in its report.

Four days later, Assad died from her injuries, according to authorities who followed up with the arrests after reviewing the video and locating the suspects.

'We know he understands the pain we are experiencing,' Assad's son-in-law Wayne Brown said in a statement, referring to the unsolved, shooting murder of Leonard's father in 2008

NBA forward Kawhi Leonard (above) signed a contract with the Los Angeles Clippers worth more than $100 million two months ago. He was only 16 when his father was gunned down outside his car wash in 2008

According to court documents, an investigator requested that the suspects be held without bail because he feared Williams' family had the financial resources to get her released.

'Williams has family that are well off and could post her bail of $1,000,000,' the investigator wrote, according to the Press-Enterprise. 'I am requesting NO BAIL to assure Williams' appearance in court and to keep innocent victims safe.'

Contacted at her home in Moreno Valley on Saturday, Woodard said she didn't know if her niece was contacted by her brother after the arrest, reports the Press Enterprise.

Woodward did not immediately respond when DailyMail.com reached out.

Jail records show that Williams is 6-foot-2, just five inches shy of her brother, who is 6-foot-7.

However, at 320 pounds, she outweighs him by almost 100 pounds. Her previous criminal record includes grand theft auto and attempted robbery.

The new charges against Williams and Townsel include, murder, robbery, elder abuse and a special circumstance of committing a robbery during a murder that makes them eligible for the death penalty.

The district attorney has not decided whether to seek that penalty or life in prison without the possibility of parole, Hall previously told the Press-Enterprise.
