A woman faces murder charges for allegedly killing a man outside her home.
Police say 52-year-old Donna Wheeler shot and killed 52-year-old James Sparks Friday night.
Wheeler's step brother, Robert Hall, said the pair dated on and off for a year, but had a troubled relationship.
The Johnson County Sheriff's Department said deputies have responded to complaints about the couple in the past.
Wheeler is in the Big Sandy Jail, on a $1 million bond.
