A Tennessee bombing that claimed the life of Jon and Marion Setzer at their rural home Monday has now led to the arrest of Tennessee man Richard Parker – the son-in-law of the Setzers. Parker was arrested and is being held on a $1 million bond, reports CNN on Thursday.
The powerful mailbox bomb killed Jon and Marion. Parker, 49, was charged with two counts of first-degree murder.
Investigators accused Parker of placing the bomb in his in-law’s mailbox. The package was being brought into the home by Jon, and as he was opening it in his driveway, the bomb went off, killing 74-year-old Jon and shattering windows of the Lebanon home he shared with his wife.
Marion, 72, was critically injured and died Wednesday night at Vanderbilt University Hospital.
Parker lives in a home behind his in-laws; the two share a driveway. Officials said mail carriers did not handle the parcel. It appears to have been placed into the Setzer’s mailbox directly by Parker.
"With the house as well-built as it was, it had to be a huge explosion," neighbor David Hughen told WTVF-TV of the home built just four years ago. "It's just a huge mystery that a terrible thing has happened to good people."
Although the motive for the killing is unclear, Parker does have a criminal record – In 1993 he was convicted of arson in Giles County and sentenced to four months of probation.
Jon was a retired attorney. Marion had worked for John Lloyd, a retired dentist, who commented on the tragic incident.
“They were two of the finest people I ever knew, good Christian people who loved their children,” Lloyd said, adding he attended church with both Jon and Marion.
