Authorities charged the wife of slain Ada’s pastor David Evans and her lover with his murder. They took 47-year-old Kristie Evans into custody at the Ada Police Department when she came in and confessed her involvement with OSBI agents. They arrested 26-year-old Kahlil Deamie Square on the same charge. Harmony Free Will Baptist Church pastor David Evans was shot last Monday morning at his residence. His wife initially told investigators intruders killed him.
