The murkiness of O. J. Simpson’s robbery-kidnapping trial in Las Vegas expands as jurors began Thursday to listen to audio recordings secretly taped during the Sept. 2007 confrontation between the former football star, his posse of men and two dealers in a Las Vegas hotel room.

The jury in the ongoing armed robbery and kidnapping trial of former football star O. J. Simpson began Thursday to listen to long hours of comments made by the various people who on Sept. 13 last year entered one specific room at the Palace Station Hotel & Casino.

The room belonged to sports memorabilia dealer and alleged victim Bruce Fromong. Simpson is accused of having entered the room with a group of men, threatening Fromong and another dealer and leaving with memorabilia worth a fortune. One of the men in Simpson’s group allegedly had a gun and threatened the dealers with it.

Simpson claims he only wished to retrieve what was rightfully his, including photographs of his children and late parents. He faces 12 charges in connection with the incident, including kidnapping, which carries a potential life sentence, robbery with a deadly weapon, burglary with a firearm, assault with a deadly weapon, coercion and conspiracy.

A recorder was hidden by Thomas Riccio, an auctioneer, on top of an armoire, which neither the dealers nor Simpson and his crew, nor the police officers who later searched the room, observed, reports The Los Angeles Times.

Jurors heard Thursday how a man identified as Simpson says, “I’m gonna show up with a bunch of the boys and take the [stuff] back,” and “It’s my stuff. They stole it.”

Another interesting comment jurors heard Thursday on a tape was from a police investigator who says, according to a transcript, “This is great. ... California can’t get him. ... Now we’ll be able to,” as quoted by the Times.

This is a clear reference to Simpson’s acquittal in 1995 on murder charges.

Clark County District Court Judge Jackie Glass was adamant during jury selection last week that the prospective jurors do not prejudge Simpson’s guilt or innocence in the current case based on their perspective of the 1995 murder trial.

Jurors are to listen to more recordings Friday. Two FBI forensic audio experts have testified that the audio recordings, which are not at all times clear and easily comprehensible, may or may not have been tampered with, according to The Associated Press. Police transcripts have come under questioning as well, with Judge Glass ruling that the jury consider the recordings evidence, but not the transcripts.
