Police say Schmidt and her husband started arguing with the Hinsons, then Tanya Schmidt grabbed a shotgun and started shooting.
"She gave a statement to police and she also outlined what her actions were and why and that she acted in self defense," said defense attorney Anthony Osso. "She feared for her own life and her husband's as well. So we'll examine those facts."
Neighbors said the shooting resulted from an ongoing feud between the Schmidts and Hinsons.
