A Callaway County man will avoid the death penalty, but spend the rest of his life in prison. That’s the plea deal struck in the case of Dale Horton. Horton admitted in court Thursday that he killed his mother Sherry Horton and his brother in law Joshua Griffin on April 26th, 2016. Horton’s girlfriend Jennifer Grayson is also charged with murder in the case. She faces a trial in November. Prosecutors and the sheriff’s department won’t comment on a motive for the killings.
