LAS VEGAS, Nevada (CNN) -- Former gridiron great O.J. Simpson was found guilty of all 12 counts in the armed robbery of two sports memorabilia dealers at a Las Vegas, Nevada, casino hotel last year.
Simpson, 61, and his co-defendant Clarence "C.J." Stewart, 54, were charged with a dozen offenses stemming from the alleged sports memorabilia heist.
Stewart was also found guilty of the same charges as Simpson. Both men will likely spend the rest of their lives in prison.
Simpson arrived at the Clark County Justice Center at around 10:50 p.m. (1:50 a.m. Saturday ET). He told CNN's Ted Rowlands on the phone before the verdict was read that he was "apprehensive."
The jury of nine men and three women, none of them African-American, began deliberations Friday after hearing from 22 witnesses over 12 days of testimony. Chief among the witnesses were seven of the nine people inside Room 1203 of the Palace Station Hotel and Casino for the September 13, 2007 confrontation.
The evidence included testimony from the two dealers, four co-defendants who cut plea deals and cooperated with prosecutors and hours of often-profane, crackling, secretly recorded audiotapes.
Prosecutors alleged that the men, led by Simpson, burst into the room, flashed a gun and threatened memorabilia dealers Bruce Fromong and Al Beardsley.
The men then filled two pillowcases with Simpson trinkets, signed Pete Rose baseballs and Joe Montana lithographs. Simpson's defense attorneys maintained their client was merely trying to retrieve personal photographs and other mementos that belonged to him.
Neither Simpson nor his co-defendant Clarence "C.J." Stewart testified during the trial. Instead, their attorneys savaged the motives of the other witnesses.
Simpson's lawyer, Yale Galanter, said Simpson was a target of investigators from the very beginning. The case "has taken on a life of its own because of Mr. Simpson's involvement," he added.
"Every cooperator, every person who had a gun, every person who had an ulterior motive, every person who signed a book deal, every person who got paid money, the police, the district attorney's office is only interested in one thing: Mr. Simpson," Galanter said.
Stewart was characterized by his lawyer, E. Brent Bryson, as the trial's forgotten player.
The most compelling evidence for all sides came from the audiotapes.
For the prosecution, conversations taped by collectibles middleman Thomas Riccio took jurors from the poolside planning to the profanity-laced hotel room confrontation.
Riccio, a chatty sports memorabilia dealer and convicted felon made the rounds on network news shows immediately after the hotel room fracas. He admitted on the stand that various media outlets paid him $210,000.
The crucial evidence for the defense came from two audiotapes, a voicemail from a key prosecution witness who seemed willing to tailor his testimony for a price and tapes of Las Vegas police officers laughing and joking about Simpson's Los Angeles acquittal following his arrest.
Galanter told jurors the surreptitious recording captured police investigators in the hotel room after the confrontation. "They're making jokes. They're saying things like, 'We're gonna get him,"' he said.
Police were called to the hotel around 8 p.m. on September 13, 2007. Shortly after midnight, detectives visited Simpson at his hotel. He told them he was just trying to recover property that had been stolen from him.
Thirteen years to the day after OJ Simpson was acquitted of murder, he had the book thrown at him.
