Williams's 11-year-old daughter, Zaria, was killed in a six-car wreck caused by a hit-and-run driver. Williams's cousin, Cedric Page, also died in the crash.
"I haven't been able to go back to work, I haven't been able to do anything, because all I can think about is Zaria and Cedric," said Williams.
No arrests have been made, but the California Highway Patrol says the investigation has taken a turn. Back in June, they believed the hit-and-run suspect was driving a black Honda or Acura. However, they now think it might be someone else. They're waiting for paint work to get back from the Department of Justice to determine what kind of car they suspect is driving.
Meanwhile, Williams hopes the suspect turns himself in.
"We just don't know what happened and why it happened. And I guess if you know, please just do the right thing. Do the right thing for Zaria. My 11-year-old didn't deserve to die," said Williams.
Williams held a memorial car wash three weeks ago to raise money for a reward, but it will take a tip from the public to solve the crime.
