An Ordinary Killer on AllMovie

Two generations of detectives struggle for 28 years to crack a seemingly impenetrable murder case only to discover that their tenacity has paid off thanks to advances in forensic technology and the art of criminal profiling in directors Anthony Hornus and Jeff Kennedy's real-life tale of belated justice. The year is 1973, and the murder of a young mother has rocked a small Michigan community. As the outraged citizens pull together to assist the investigation, the police attempt to use emerging forensics technology to narrow down the list of suspects with little to no luck. The victim's mother stricken with grief and forced to look to a higher power for solace, the crime goes unsolved until advancements in DNA identification and criminal psychological profiling finally puts a face to the evil that haunted a community for nearly three decades.
