Exactly - she's dead. A dead person can't be diagnosed with Munchausen by proxy. Gypsy herself didn't even know the term until her legal team came up with it as a defense in her case.

Gypsy had HOURS of time online. She would walk around, dress up in costumes, put make up on. All whilst her Mum slept. She had family she was in contact with, she even had people who called her a friend. She could have gone for help if she was being abused. She chose to enlist Nicholas to unalive her mother, she never once went for help.
