This woman told the post office that the package contained a robot.
It actually contained a puppy.
Clearly, she is mentally sound enough to lie in an attempt to illegally mail a live animal.
She also told the judge that she put a bottle of water in the box for the dog. I’m guessing that came up in the mental competency hearing - Along with her putting little holes in the box for air, but which she sealed over with tape when she was sealing the package.
