LEBANON, Tenn. (AP) -- A Tennessee man has pleaded guilty to charges that he killed his mother- and father-in-law with a package bomb.
Richard Parker entered the plea Tuesday in Wilson County Circuit Court in a deal that calls for him to serve life in prison without parole.
Parker is the son-in-law of Jon and Marion Setzer, who were killed after a package bomb exploded at their house in February. Parker lived directly behind them in rural Wilson County, which is about 30 miles east of Nashville.
Prosecutors also revealed a motive in the deaths, saying Parker owed the Setzers thousands of dollars.
The blast killed 74-year-old Jon Setzer, a retired lawyer. His wife, 72-year-old Marion Setzer later died at a Nashville hospital from her injuries.
