Reportedly, the other driver's husband, Jerome Barson, a 78-year-old man, was in the vehicle with her and suffered head trauma and was taken to the ICU, where he died two weeks later. Those injuries led to Barson being in intensive care for two weeks before dying on Sunday, according to TMZ.
Williams reportedly told police that she had gotten stuck in the intersection when traffic ahead of her slowed down. Barson's wife, who was driving the auto at the time of the accident, suffered broken bones and other injuries.
According to TMZ, Barson's wife told police she T-boned Williams' SUV traveling westbound in Palm Beach Gardens, Fla., after the athlete abruptly entered an intersection heading northbound. There is no evidence that Williams was under the influence of drugs or alcohol, or driving distracted.
Police said Williams, a seven-time Grand Slam victor, was at fault because she violated the other driver's right of way. Barson's wife was reportedly also hospitalized for injuries, including broken bones.
The TMZ report does not indicate whether Williams is expected to face any charges.
