The OSBI says an arrest has been made in a Checotah homicide nearly one year ago. The victim, 57-year-old Deborah Kelso, was shot in the head and her home was set on fire. The OSBI says 53-year-old Steven Lee Vanzant was booked into the McIntosh County Criminal Justice Center Thursday on one count of first-degree murder. The two had been living together. His bond was set at $2 million.
