The lurid case of reality-show producer Bruce Beresford-Redman has provided grist for the Hollywood gossip mill for a few years now, and on Saturday, “48 Hours” will give the wheel another spin.

The CBS newsmagazine will present selections from a video diary Bresford-Redman has produced with a GoPro on which he avows his innocence.

In 2010, Monica Beresford-Redman, 42, was found dead and naked in a sewer on the property of the Moon Palace Resort in Cancun, Mexico. She was on vacation with her husband, Bruce, a longtime producer for reality shows like “Survivor” and their two children. Bruce Beresford-Redman was questioned by Mexican authorities and then returned to California. He was later detained in California and extradited to Cancun, where he’s been on trial for murdering his wife.

“I am accused of the murder of my wife Monica, a crime I did not commit,” Beresford-Redman says in one selection from the video diary. The video is collected from a four-month period in which Beresford agreed to offer people  a chance to “understand what can happen, to get an idea of, what things are like here in hell.”

He remains incarcerated with upwards of 10 others in a 12 x 15-foot cell designed for three people.  In the coming episode, he describes the Mexican prison system as a dirty, rat-infested village with razor wire around it. There are about 1.800 men, women and some children living in a prison originally built for 700 people.

Before their Mexican vacation, the Beresford-Redmans lived in Los Angeles, where Monica Beresford-Redman owned a restaurant. A month before making the trip, the husband admitted to having an affair.

Beresford-Redman sat down for an on-camera interview with correspondent  Troy Roberts, who also reported on the case for “48 Hours” in 2012. The show will also use interviews with the suspect as well as his parents and his wife’s sisters, among others.
