The trial of a Lebanon business man accused of killing a father and his teenage son back in July has been moved to Camden County. Earlier this week, a motion for a change of venue was granted for 65 year old Matthew Rumbaugh. The dates for a jury trial have not yet been set. Rumbaugh has been charged with two counts of first degree murder and armed criminal action for allegedly killing 35 year old Chad Gerber and his 15 year old son, Riley.
