Secrets Uncovered: Where Is Robin Hoynes Today and Who Killed Him? Dateline: Secrets Uncovered will explore the terrifying murder at a Torrance KFC location on Wednesday. On October 30, 1984, the killer stabbed Robin Hoynes to death before slitting his throat. Because the killer, William Charles Marshall, was able to escape justice through deception and a false alibi, his case remained unsolved for more than 20 years.

The Night Before Halloween, the next episode, will air on Wednesday, August 3. A deep journalistic dive into the case will be taken to provide a blend of the facts and the tragic events that followed the murder.

The official synopsis for Wednesday night’s episode of Dateline: Secrets Uncovered is as follows:

“It takes a single eye to see the object that is out of place at the crime scene; in this case, that thing seems so insignificant that nobody knows what it is or what it means; it takes a team of determined researchers nearly two decades to find out,” reads the book’s subtitle.

Date Line: Whatever Happened to Robin Hoynes? – Secrets discovered

On the night before Halloween in 1984, Whittier resident Robin Hoynes, then 21, was brutally murdered. She was employed at Kentucky Fried Chicken in Torrance as an assistant manager at the time of his death.

Before the killer cut his throat, he was stabbed twice in the back. Authorities say Hoynes was the subject of an attempted robbery while working on paperwork after work. The circumstances surrounding his death will be further examined in the next episode of Dateline: Secrets Uncovered.

The next morning, her co-worker Cheryl Muller found her dead and found the scene in disarray. She claimed that she and Hoynes had stopped work that night, and the next morning, she woke up to find her car still parked outside hers. Near her body, there was additional trash and paperwork lying around.

Date Line: Who Killed Robin Hoynes? secrets discovered

Before he was fired, just days before the murder, William Charles Marshall, another co-worker who had been working with Hoynes, was still employed. He has a long history of suspected embezzlement of office cash.

Police arrested Marshall in connection with the murder 12 days after the incident. Prosecutors at the time did not press charges, so he was released. His ex-girlfriend welcomed him home and they had dinner together the night of the murder.

Until 2005, when the Torrance Police Department began reviewing several cold cases, the case remained cold. An unimportant piece of foam discovered at the crime scene in 1984 unexpectedly turned out to be the most important piece of evidence when it was linked to Marshall’s boots.

Marshall was also aware of the combination to the safe as a former assistant manager, although he was unaware that it had been altered after he was fired. He killed Hoynes in a surprise attack when he entered the building that night to commit a robbery, but was unable to steal any money because he did not know the new combination.

Secrets Revealed – Where Is William Marshall Right Now?

Marshall was arrested once again in 2006 at his fire station. He was a captain with the State Department of Forestry and Fire Protection in Thousand Palms, a town in the Coachella Valley, at the age of 46.

Nearly 23 years after Robin Hoynes’s death, a jury found Marshall guilty in 2007 after four weeks of testimony. He watched the proceedings and the emotional testimony of the Hoynes family from a seat in the courtroom that showed no expression or movement.

Judge Mark S. Arnold of the Los Angeles County Superior Court gave him life in prison without the possibility of release. He is still incarcerated and completing his term as of this time.
