"He got away with murder," Clark says in the current issue of PEOPLE. "I hated the way the media attention on the trial impacted the case – the way it impacted the witnesses. Everyone forgot Ron and Nicole and it became this enormous circus. That was harmful to [our case.]"
And now the lawyer has hopes that the Los Angeles Police Department has uncovered a crucial piece of evidence that could have helped her get a different verdict at the 1995 trial: the murder weapon.
The LAPD confirmed that investigators are in possession of knife found buried on Simpson's property some time after he was acquitted of murdering his wife and her friend.
The LAPD has admitted the knife could have been planted as a hoax – a theory Clark says is a possibility as well – but she is hoping it is the real thing.

"I really don't know what to think of it. I can't believe someone gave a police officer what appears to be, could be, important evidence in a case – even if it is closed – and takes it home. I don't know what to say about that except I can't believe it, but it's apparently what happened," Clark told Entertainment Tonight on Friday.
"I don't know whether to say it is truly evidence, none of us knows that yet – it might be a hoax, it might be somebody who planted it and then just pretended to find it and gave it to the off-duty police officer, you don't know," she continued. "But, of course, I'm glad the LAPD is taking it seriously and subjecting it to testing so we can find out."
But even if DNA evidence can link the knife to Simpson and the murders, Clark admitted that there is little chance of prosecution.
"The likelihood of any prosecution stemming from this evidence is very, very slim. But we have to find out what this means – what the truth of this is," she said. "I just hope the truth comes out about this situation, as I always do about all situations – whatever this is, let's find out."
