Police said Mercedes Robb called 911 about 6:30 a.m. Thursday to report having shot her ex-husband.
Their two children were at her house at 3112 Oregonia Road, outside Lebanon at the time of the shooting, but were uninjured.
The children did not witness the shooting, according to Lt. John Faine, with the Warren County Sheriff’s Office. Childrens Services workers were called to the scene.
Jason Robb was shot multiple times in the yard, and deputies found his body there upon their arrival, Faine said.
He was there to pick up their children — a routine exchange prior to the school day, Faine said.
In the 911 call, Faine said, Mercedes Robb said she shot her ex-husband and that he was not breathing, but declined to attempt to revive him. She agreed to cooperate with the deputies at the scene and was arrested without incident.
Investigators found no wounds on her indicating the shooting was in self-defense, Faine said.
Jason Robb had no weapon and his vehicle was still running in the driveway when deputies arrived, Faine said.
