 Shannon Doherty died Saturday after years with breast cancer at the age of 53. She was a child star in the early 1980s. She played Jenny Wilder on Little House on the Prairie. A later generation knew her as Brenda Walsh from Beverly Hills 90210. Brenda, come back. We need to talk. I am finished talking. Now I'm going upstairs and I'm going to pack and then I'm leaving this house. And I don't want either one of you to try and stop me.
