Her murder went unsolved for nearly 40 years.

Rose Ann Hlavka came home to the modest brick apartment building just northwest of Portland, Ore.’s downtown around 10 p.m. expecting to find her 20-year-old sister, Anna Marie. The siblings not only shared a home but they both also worked at a nearby McDonald’s, where Anna Marie Hlavka had gotten off a few hours earlier.
But her sister didn’t answer when Rose Ann opened the door and called her name on that night, July 24, 1979. She soon discovered why: Anna Marie was sprawled dead in the bedroom. She had been strangled and sexually assaulted.
