The family of a man who died in a car crash involving Venus Williams plan to sue the tennis superstar, a lawyer said Friday.

Attorney Michael Steinger told ABC television's "Good Morning America" that the family of Jerome Barson would file a wrongful death suit against Williams following the June 9 crash in Palm Beach Gardens, Florida.

Barson, who suffered head injuries in the accident, died two weeks later on June 22.

"At this point we are attempting to both preserve the evidence and gain access to evidence," Steinger said.

According to a police report, Williams' 2010 Toyota Sequoia SUV was in collision with a 2016 Hyundai Accent driven by Barson's wife, Linda Barson.

The police report described Williams as being "at fault" in the incident. The accident remains under investigation and she has not been charged.
