OJ Simpson allegedly confessed on tape to killing his ex-wife Nicole Brown Simpson and her friend, his former bodyguard claimed – but the apparent recording has been embroiled in a messy legal battle for months, according to court documents.

The so-called confession is said to be on a USB stick that police officers in Bloomington, Minnesota, seized from Simpson’s ex-bodyguard Iroc Avelli when he was arrested in an unrelated incident in 2022, TMZ reported.

However, Avelli didn’t alert police to what was allegedly on the device until earlier this year – just two months after Simpson’s April death in Las Vegas, according to a search warrant.

Acting on Avelli’s tip, a judge granted police a new search warrant in June to examine the USB drive – but the results are still pending, court documents say.

The saga was dragged out as Avelli and his lawyers filed legal action to get his possessions back, law enforcement sources told the medium.

The drive, still in police possession, was among a handful of similar devices and ammunition found in Avelli’s green backpack at the time of his arrest.

It was not immediately clear whether police had examined the contents of the USB stick or whether the apparent confession was even on the device.

Avelli allegedly claimed that in the recording, Simpson also implicated an unknown third party in the double murder.

Simpson was charged with the horrific 1994 murders of his ex-wife and her friend Ronald Goldman in Los Angeles.

The once-popular NFL superstar was acquitted a year later after a blockbuster trial.

Although he avoided prison time for murder, a separate civil trial jury found him liable for the deaths in 1997.

Simpson died in April at his home in Las Vegas at age 76 after a battle with prostate cancer.
