A cookout in Tennessee ended in tragedy over the weekend when a 3-year-old child accidentally shot and killed the wife of a Wilson County sheriff’s deputy.

According to WSMV, the toddler found the pistol and discharged it during a gathering at Deputy Daniel Fanning’s residence on Saturday.

Deputies said that 48-year-old Josephine G. Fanning was dead by the time they arrived on the scene. The 3-year-old child was reportedly related to the Fannings.

The Tennessee Bureau of Investigation (TBI) determined that the pistol belonged to Deputy Fanning.
