A movie from late 80´s or early 90´s I think, always thought it was called "The babysitter", but I can´t find it- In the end the babysitter, who has long, blonde, curly hair, and she was rather pretty, bounces some small bouncy balls off a roof top or so and she jumpes off herself and crashes down into the asphalt and dies. What was it called? Thanks.

The Sitter (http://www.imdb.com/title/tt0102938/)
