Advice for my sister who was raped

I need advice from anyone who had been through this it has helped someone through this.

My sister was raped last night and I'm driving several hours to go be with her. Anything that helped you or someone else get through this?

Police took her bedding (including her FAVORITE blanket) which I'm picking up a similar one bc shes so upset without it. I know being there will help, but I think going in with some advice will help.
