A two-part TV documentary will look at a horrifying string of homicides that remains a mystery — the infamous Oakland County Child Killer case of the 1970s.

Airing on Feb. 18 and 19 on Investigation Discovery, the cable TV event will trace the decades-long attempts to solve the murders of four children in metro Detroit that took place between 1976 and 1977.

"Children of the Snow" will focus on the efforts of J. Reuben Appelman, author of the 2018 book "The Kill Jar: Obsession, Descent, and a Hunt for Detroit's Most Notorious Serial Killer," Detective Cory Williams of the Livonia Police Department and the relatives of the victims.

The quest continues to find who was responsible for the deaths of Timothy King, 11; Mark Stebbins, 12; Jill Robinson, 12; and Kristine Mihelich, 10. The crimes plunged the region into fear for more than a year and continue to haunt longtime residents.

The documentary will explore Appelman's suspicions that money and influence may have kept the killer from being discovered. It also delves into a theory involving a link between the murders and a pedophile ring.

Meet notorious Michigan serial killers

Although many clues and suspects have been examined, the case is still unsolved. The news release for "Children of the Snow" hints, however, that science "may finally unlock the answer from old evidence" more than four decades after the fact.

In 2018, the Free Press wrote about notorious Michigan serial killers, including the ongoing search for the Oakland County Child Killer, noting that "police have chased down multiple leads over the years."
