Patricia Anderson, 43, was found dead in her ground-floor Indianapolis apartment after a fire in the early hours of Sunday, July 30, 1973. Her 18-year-old daughter had left the previous evening; a neighbor saw smoke and a young man leaving the building who, when confronted, told the neighbor don’t bother her. She was discovered about six feet from her front door with burns over much of her body.

Investigators initially treated the blaze, which began in two separate locations—the living room couch and the bedroom—and caused roughly $10,000 in damage, as the cause of death. The absence of Patricia’s purse and wallet led police to consider robbery. An autopsy later showed she had been stabbed 21 times in the face, neck, and rib cage with a very sharp, thin-bladed weapon, and the fires were judged to have been set with a flammable liquid to conceal the murder. No arrests were made and the case went cold.

Did anyone in Indianapolis in 1973 recognize the man described by the neighbor or have information about solicitors in the building that summer?
