LANCASTER, Ohio (WCMH) -- The Fairfield County Sheriff's Office is investigating an aggravated murder. According to Fairfield County Sheriff Alex Lape, the sheriff's enforcement bureau responded to a home on the 3000 block of Tschopp Road in Lancaster on Jan. 17. At the residence, officers found Darby Russell, 51, dead from a gunshot wound. Lape said Kimberly Russell, 44, was detained, arrested and booked into the Fairfield County Jail on one count of aggravated murder. Less than a month ago, a social media post from a Kimberly Russell married to a Darby Russell living in Lancaster show a couple together, with the caption dubbing Darby the "love of her life" and stating Kimberly had never been happier. Lape said his office is still actively investigating the case and invited anyone with knowledge of the incident to use the "submit a tip" feature on the Fairfield County Sheriff's Office app, or call 740-652-7911.
