Son-in-law charged in fatal Tennessee package bombing

Matt Smith and Tom Watkins cnn.com 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. Wilson County Sheriff Robert Bryan said Parker lived next door to his in-laws. Investigators would not discuss a motive and provided little detail about the case against Parker, but Gwyn said he is the sole suspect in the Setzers' deaths. "Right now we feel like we have the person responsible for committing this crime in custody," he said. Parker was convicted of arson in 1993, for which he served four years on probation, the TBI said. Amid the debris, investigators found a note they said may have been attached to the bomb, but would not divulge its contents. "This is a very important piece of evidence, because now you may have handwriting," said former ATF agent and bomb expert Joseph Vince. Authorities originally said they thought the bomb had been delivered by the U.S. Postal Service, but on Thursday they said they now believe that was not the case. Officials said Setzer picked up the package from his mailbox, about 200 yards from the home. It detonated just inside the house, killing him and mortally wounding his wife. to read more: cnn.com
