On August 22, 2019, 15-year-old Jonathan Jon Nathaniel Horath was found dead at his home in Madill, Oklahoma. His mother, Monica Horath, and his 12-year-old sister, Stephanie Horath, were also found deceased; all three had fatal gunshot wounds. Jonathan was a student at Madill High School and active in track.

Investigators focused on Monica’s husband and Jonathan’s stepfather, Kevin Moseley, after a friend in New Jersey reported that Moseley had confessed to shooting his wife and stepchildren. Cell phone triangulation by the Marshall County Sheriff’s Office and the Oklahoma State Bureau of Investigation tracked Moseley to Abilene, Texas, where he was taken into custody and later extradited to Marshall County to face charges in the three murders. Reports say Moseley initially pleaded not guilty and later changed his plea to guilty; he was sentenced for the killings.

What details about the family or their final days might help explain what happened, and can anyone who knew them add reliable information?
