O.J. Simpson was tried and and acquitted for the 1994 murders of his ex-wife, Nicole Brown, and her friend, Ron Goldman.
Simpson, who currently lives in a golf course community in Las Vegas, is on parole after his 2017 prison release.
The trial of the century spanned nine months yet the jury found Simpson not guilty of the murders of Nicole Brown Simpson and Ronald Goldman in under four hours.
The planned July 9 reveal would have coincided with Simpson's 73rd birthday—which a Ford spokesman previously said was "purely coincidental."
The lawyer blasts the family of slain Ron as 'professional victims.'
Officers are still investigating exactly where and when the alleged knife was found.
