Jackie the babysitter

Jackie the babysitter was put in charge of babysitting Amy Lutz in the Amityville house.

History
Jackie can first been seen as Jimmy, Kathleen and George interact in the house. She later can be seen telling Amy that she was instructed to give her medicine and put her to bed, for which Amy said she doesn't want to go to bed and she wants to play with Jodie. As Jackie was looking for Amy's pajamas in the closet, the door shut on her. She found that she couldn't open the door and that she was trapped in there. She kept yelling at Amy to open the door, but she wouldn't. Then the light in the closet went out and Jackie let out a loud scream.

When the Lutz family got home from Jimmy's wedding, they ran up the stairs to Amy's room when they heard Jackie yelling. She was found, knuckles bleeding and some of her blood on the door. She was clearly pissed at Amy. George noted to Jackie's claim that the door can not be locked despite what Jackie was saying. However, he and Kathy were also mad at Amy for not opening the door for Jackie.

Trivia
In the scene where George was showing the door is not lockable, he calls Jackie "Amy" the actresses real name.
