In September 2016, 41-year-old Shawn Grate was arrested in connection with the kidnapping and sexual assault of one woman, and the kidnapping and strangulation deaths of two others in Ashland County, Ohio. Charged with two counts of aggravated murder in the deaths of Stacey Stanley and Elizabeth Griffith, Grate was convicted of the murders on May 7, 2018, having already pleaded guilty to 15 other felony charges, including rape, during the trial. He has also confessed to killing three additional women, including one whose remains were found in 2007, but has yet to be charged with those murders.

“He was extremely handsome. He had a great smile and sweetness about his eyes,” she says, adding, “He was very kind and very compassionate.” Amber says she fell head-over-heels in love.
