The son-in-law of the elderly couple killed this week in a package bomb explosion at their Tennessee home has been charged in the case, authorities said Thursday evening. A grand jury returned indictments of felony first-degree murder and felony first-degree premeditated murder against Richard Parker, 49, police said at a press conference. Authorities would not elaborate on how they came to identify him as the suspect, and said he was arrested at his home on Thursday.
