Sandy, How is Krysten doing? How are you handling all of this? I would imagine it has been very hard on you. I pray that your dd will come and talk with you as she continues to process this.
This has led me to re-visit the issue with my dd who is just a little younger than Krysten. The fact that you have shared this with us may help another young lady.
Last night on the local news, they led with a story about the increase of rapes due to these drugs. Here is a link to the story - I don't know if anything in there would be helpful to you, but maybe for others that have heard Krysten's story
