This isn't Old Hollywood, but it did happen back in the day. This actress was probably A- list when she was killed. She was headed to A list. She was the co-lead on a brand new show that was set to be a massive hit. Her husband, a celebrity offspring was jealous of her success and jealous of the time she was spending with another man. Even though the couple had separated, he wanted the actress all to himself and killed her. He did so at the perfect time. There had been a crime spree the days leading up to her death which saw random killings of couples and women and several armed robberies. It took so long for the police to realize those suspects were not the suspects in the death of the actress, they had no clues or witnesses and our killer was never brought to justice.
