She is charged with the murder of Cindy Caudill and the attempted murder of her brother Bill Couch and Wednesday afternoon Sarah Melton told her side of the story.
The defense called Melton to the stand first in an effort to prove her actions on June 28th, 2011 were all in self defense.
Melton claims Bill Couch has a history of domestic violence and his threats caused her to fear for her and her children's lives.
The trial ended early Wednesday due to evidence issues.
It is expected to resume Friday afternoon.
