A central Ohio man has been sentenced to 18 years in prison under a plea bargain for fatally stabbing a Columbus grandmother and wounding her 7-year-old grandson.
30-year-old Kristopher Amos pleaded guilty to involuntary manslaughter Wednesday in the death of 45-year-old Candy Arthurs and felonious assault for stabbing the grandson while they were helping him find a missing drone near Oakley Avenue. A motive remains unclear. Amos' attorney says he has mental health issues. Amos is a twice convicted sex offender.
