Robert Horn, 55, of the 200 block of Bobby Davis Road, Shongaloo, is charged with attempted manslaughter and remaining on premises after being forbidden.
WPSO Chief Deputy Bobby Igo said investigators contacted Horn Thursday and asked him to come to the courthouse for additional questioning.
"It was at this time that detectives (T.D.) Kemp and (Scott) Tucker placed him under arrest," Igo said.
According to reports, Tuesday around 6 p.m., Horn took a 9mm handgun and went to the residence of 40-year-old Cheryl Sanders in the 600 block of Firetower Road to confront her about a problem between their children who allegedly were having relationship issues.
"When he went to her residence, he had someone else with him ... in another vehicle," Igo said. "Sanders was alone. She says she came outside to talk to him and they got into an argument. She ordered him to leave several times and when he didn't, she went back into the house – she says to call the police. She armed herself with a .22 revolver and went back outside when she heard a car start – thinking he had left."
When Sanders returned to her front porch, she found Horn was still there and allegedly pointing a gun at her.
"The argument continued and Sanders was shot twice – once in the chest and another time in the side," Igo said. "That bullet passed through her arm. She was left with a damaged liver, spleen, lungs and diaphragm."
Sanders was airlifted to LSU Medical Center where she underwent surgery and remains in the Intensive Care Unit.
"She's breathing on her own, but she still has a lot of tubes," Igo said.
Horn was detained briefly for questioning Tuesday night, but he was released until his arrest Thursday.
Igo said investigators interviewed Horn and Sanders before determining charges. Reports showed both guns were fired, but Horn was not hit.
"We don't feel it really matters who shot first," Igo said. "In this case, he was determined by law to be the aggressor, therefore he cannot claim self-defense."
Horn is being held at Bayou Dorcheat Correctional Center under bonds totalling $100,500.
