(CNN) — The son-in-law of a couple killed in a bombing at their rural Tennessee home has been charged with planting the deadly device, authorities announced Thursday.
Investigators arrested 49-year-old Richard Parker on two counts of felony first-degree murder and two counts of felony premeditated murder in connection with a package bomb that exploded at the rural Tennessee home of Jon and and Marion Setzer, investigators announced Thursday. Bond was set at $1 million, said Mark Gwyn, director of the Tennessee Bureau of Investigation.
Jon Setzer, a retired lawyer, died Monday when the package bomb detonated outside their home near Lebanon, about 30 miles east of Nashville. Marion Setzer died Wednesday evening at Vanderbilt Hospital. He was 74; she was 72.
