An excerpt posted by Elizabeth's sister, Laura, from www.squidoo.com/ElizabethPfeifer...

My sister, Elizabeth Ann Pfeifer, disappeared into the night April 12, 1986.

She was at home in Katy, Texas, where we grew up. She lived there with my parents, I happened to be visiting that evening. She was getting ready to attend a party in North Katy, in a subdivision down Morton Road. She told me that she was going with five other people...

She left that evening and never returned.

I never saw her again.
