Police in southwest Ohio say a woman called 911 to report that she shot her ex-husband in the head during an argument.
Middletown police say the 45-year-old man died at a hospital after the Monday night shooting at the couple's home.
The woman, Dawn Shearer, has been jailed on suspicion of murder.
The Hamilton-Middletown Journal-News reports that the 46-year-old told a dispatcher that she had moved back in "to work things out" with her longtime spouse and that she shot him while they were arguing.
No attorney was listed in court records for her. She is slated to make an initial court appearance Wednesday.
Police say no one else was at the home when the shooting occurred. They say they recovered a handgun and other evidence at the scene.
