GBI agents say it appears 68-year-old William Miller shot his wife 66-year-old Sarah Miller and then took his own life.
Their bodies were discovered Saturday afternoon by their adult daughter at their home on the 700 block of Youngblood road in Sylvester.
Their bodies have been sent to Macon for autopsies.
This is the fourth murder-suicide in southwest Georgia in the last three months.
Our thoughts and prayers are with the Miller family.
