Brook Marie 1971 - 1996

Does anyone know what this is about? It's what appears to be a grave marker at the top of the Ridge Trail in the hills above Pacific Palisades. It says, "Brook Marie 1971 - 1996 She is loved." It has her picture on a small cross, and it's often decorated with fresh flowers, but I have never seen the flower bearers. I haven't been able to find anything about her on the Internet, and I'm wondering what happened to her.

UPDATE 6/5/06: On my hike this morning, I saw two people placing flowers on Brook's memorial marker. I stopped to talk, and they told me that Brook died in a car accident ten years ago. The memorial marker was placed at the top of the Ridge Trail because it was her favorite place to be.
