Investigation Discovery Premieres MY BROTHER THE SERIAL KILLER Documentary Tonight

This November, be thankful for your family, even if they're not perfect - not everyone is so lucky. Tonight, November 21 at 9 PM E/P, Investigation Discovery premieres MY BROTHER THE SERIAL KILLER, a feature-length ID Films documentary that interviews the family of serial killer Glen Rogers, who claims to have murdered more than 70 people and chronicles what happened when those closest to him discovered how evil he was. Among his many victims, the film also explores the family's claims that Glen was linked to the deaths of Nicole Brown Simpson and Ron Goldman.

"When we hear of horrific crimes, we ask ourselves 'Who would do such a thing?,'" said Henry Schleiff, president and general manager of Investigation Discovery. "Imagine the horror of discovering that the person who'd committed these gruesome crimes was sitting right next to you, your own brother."

ID FILMS: MY BROTHER THE SERIAL KILLER digs deeply into the secrets of Glen Roger's past to reveal how he became a smooth-talking killer. Glen has been directly tied to five homicides, and is suspect in over a dozen others across the country. At one point, Glen bragged that he had killed "more than 70 people" and even claimed responsibility for the murders of Nicole Brown Simpson and Ronald Goldman.

Receipts show that Glen was working as a housepainter in L.A. in 1994, and family members claimed Glen told them that he was working for Nicole Brown Simpson, and that he said she was rich and he was going to "take her down." After Nicole Brown Simpson and Ron Goldman were murdered in June of 1994, Glen embarked on a cross-country killing spree that garnered national news coverage and landed him on the FBI's 10 Most Wanted List. Glen's family tipped off police to his whereabouts and he was finally captured in November 1995 and received death sentences in California and Florida. Years later, Glen provided a detailed account of the Goldman-Brown Simpson slayings to criminal profiler Anthony Meoli. He is now awaiting execution on Florida's death row.
