A 55-year-old Port Orange woman who said she killed her neighbors because their "green mothball cookies" made her sick was found not guilty of murder by reason of insanity, according to a judge.

A judge signed an order committing Linda Sue Anderson to a Florida Department of Children and Families facility.

Anderson told Port Orange police that she hated her neighbors, Robert Goerlich, 70, and his wife, Shirley, 68, because their cookies sickened her.

Both were found shot to death by a neighbor at their home located at 110 Gregory Circle.

A short time after the shooting, Anderson was taken into custody and charged with first-degree murder.

During questioning, Anderson told police, "I didn't see any blood or bullet holes in their clothing. …They are over there watching TV aren't they? I was shooting blanks."

Anderson also said, "They make me cookies with green mothballs in them and I get sick."

Anderson had a 20-year history of mental illness, the report said.
