Nicole Brown’s sisters get emotional in doc series trailer: ‘I could not protect her’ from O.J.

A new documentary series about Nicole Brown Simpson, O.J. Simpson’s ex-wife who was gruesomely murdered in 1994, will debut on Lifetime in June, the network said.

“The Life and Murder of Nicole Brown Simpson” will be told in four parts with previously unseen archival footage and feature some 50 interview participants. It airs June 1 and 2 at 8 p.m.

According to the Hollywood Reporter, premiering the show so soon after O.J. Simpson’s death from cancer on April 10 at 76 is purely coincidental.

The doc is timed to the 30th anniversary of the deaths of Brown and her friend Ron Goldman — which occurred June 12, 1994 — and has been in the works for more than a year.

“It’s been 30 years,” says one of her three sisters in a voiceover. “Maybe it’s time to rekindle the flame of Nicole.”

Her three siblings, Denise, Dominique and Tanya, all participated.

“She was my best friend,” says Denise in the trailer. “And the one thing I could not protect her from was the monster she was married to.”

After Brown and Goldman, then 35 and 25 respectively, were found brutally killed in Brentwood, Calif., the eight-month trial of O.J. — dubbed “The Trial of the Century” — ensued. The football star was acquitted.

But in 1997, after Goldman’s father filed a civil suit against Simpson, he was found liable for the two deaths.

“I think it’s important that people get to know my sister,” says another sibling. “Our sister.”

Adds a different woman in the trailer: “We are here to vindicate her. Don’t get in our way.”
