In 1995, ET brought psychic detective John Monti to O.J. Simpson's Rockingham Ave. property in Los Angeles. Once there, he claimed to have a strong sense that there was a buried murder weapon on the land that would eventually be found.
"I can confirm almost 100 percent there's a murder weapon up there. It's buried," Monti told ET at the time. "It's going to be found."

Monti's hunch came more than 20 years before a possible new finding in the murders of Nicole Brown Simpson and Ronald Goldman was handed over last week.
Retired Los Angeles Police Department motor cop George Maycott has been identified as the police officer who presented authorities with a knife allegedly found on Simpson's property in 1998. Maycott's attorney, Trent Copeland, told ET that his client was given the knife from a construction worker who helped raze Simpson's old home. Copeland claims his client brought the knife to the attention of his LAPD bosses immediately but was overlooked.
"They said, 'Look, we're not really interested in this. We don't care,'" Copeland said. "So he took it. It stayed in his bag and his toolbox for 15 years."

Carl Douglas, who was a part of Simpson's "Dream Team," told ET that the media focus on the alleged knife discover is overblown.
"I thought it was ridiculous," Douglas said. "If the show [The People v. O.J. Simpson: American Crime Story] hadn't reawakened the curiosity of so many, I doubt it would have this level of involvement and attention."
Marcia Clark, the lead prosecutor in Simpson's murder trial, was relieved to learn that the LAPD was investigating the knife.

"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," Clark said. "But, of course, I'm glad the LAPD is taking it seriously and subjecting it to testing so we can find out."
