ASHLAND, Ohio – An episode detailing how convicted murderer Sean Grate was brought to justice will air tonight at 9 p.m. on 20/20. News 5’s Bob Jones, who covered the case, will appear on the show.

Jones had a report looking back at the case and looking ahead to tonight’s 20/20 episode on News 5 at 6 and 7. The episode is called Meet the Other Me. John Quinones is the correspondent.

“This is such a compelling story, one of the most enchanting cases I have ever covered,” Quinones said.

The investigation began in 2016 when a woman called 911 to say she had been kidnapped and held captive — a call that led police to an abandoned house in Ashland. He eventually confessed to the murders of five women.

When police went to the house, they made a gruesome discovery. Inside, investigators found a woman’s decomposing body in the basement on the cold concrete floor, buried under a pile of trash and debris. The woman was naked from the waist down and had a cloth tied around her neck.

Upstairs, authorities made another grisly discovery: a closet covered in duct tape emitting a “deplorable odor.” Inside was another body, hidden under a pile of clothing. Both women were tied up.

The women were later identified as Stacey Stanley Hicks and Liz Griffith. Authorities said both Griffith and Hicks had been strangled.

Grate is now behind bars and on death row after being convicted in 2018. He also admitted to Rebecca Leicy in Ashland County and Candace Cunningham in Richland County.

In 2019, a Jane Doe found dead in Marion County in 2007 was linked to Grate, and police confirmed she was another of his victims. She was later identified as 23-year-old Dana Nicole Lowrey. Police say she was murdered in 2006.

Much of the 20/20 episode will focus on the work of Ashland Detective Kim Mager. She has written a book about the case entitled A Hunger to Kill.

Mager, now retired, is credited with forming a bond with Grate and getting him to confess to the murders.

“She has been compared to Clarice Starling, the character played by Jodie Foster in the movie The Silence of the Lambs,” Quinones said.
