A Grove City man is in jail this morning after police say he killed his ex-wife outside an apartment when she arrived to pick up their children, then had their 13-year-old son call 911 to report the stabbing. In a recording of the Sunday morning call, the boy says his father, 38-year-old Jeremy Roberts killed his mother and then told the teen to report it. Police say officers responding to the scene found 36-year-old Candice Roberts' body in a grassy area, covered by a blanket. Jeremy Roberts remained in the Franklin County Jail this morning on one charge of murder.
