This story has been corrected to show that Johnson is 54, not 55.
The man fled the scene and was temporarily at large, police said. Authorities say Johnson killed 30-year-old Carli Cronin on Saturday afternoon during a domestic dispute in the garden section of a Walmart.
Authorities say Cronin was shot multiple times.
After the shots were fired, the man calmly exited the store. He remains in critical condition, the Ocala Star-Banner reports. Ballard said Johnson threatened Cronin, saying at one point he was "coming strapped" for her.
Ballard says the suspect wanted to get back together, but she did not.
Ocala police said this is the 12th domestic violence homicide in the county this year. Police say that the suspect left after shooting the victim, and then shot himself. Police said he was taken to the hospital and wasn't expected to survive his injuries.
Ocala police are working on contacting next of kin, the post stated. Wade described the shooter as a bald black man who was wearing brown shorts and an orange vest.
Police said the woman died.
The victim was pronounced dead, but her name has not been released.
The woman died at a hospital.
No other people were injured. They were fighting near the Walmart garden section Saturday afternoon when the woman screamed for help.
The man fled and officers are searching for him.
