On September 9, 1974, 27-year-old Nancy Carole Lossman was found murdered in her Crystal Lake, Illinois apartment. Her three-year-old daughter Lisa was also discovered dead at the scene; Nancy’s body bore multiple bite marks. Nancy’s six-year-old son Robert survived but was found unconscious from smoke inhalation.

Two years later, forensic odontologist Dr. Lowell Levine matched the bite marks on Nancy to the dental records of 26-year-old Richard Otto Macek of McHenry, Illinois. Macek had his teeth removed shortly after the murders. In 1976 he was indicted for the deaths of Nancy and Lisa Lossman; he pleaded guilty to Nancy’s murder and received a sentence of 200 to 400 years. Macek was also convicted in other violent crimes, including the 1974 murder of Paula Cupit in Wisconsin.

Does anyone have additional information about Nancy, Lisa, or the surviving child Robert, or remember the investigation in the Crystal Lake area?
