A friend of mine on Facebook posted this update today. If you were on the river on Friday afternoon, and know of or saw this interaction, please contact the police:
Hi friends. Amy is still missing, but new information indicates Amy was seen near the river with someone on Friday afternoon July 8 in Clear Creek Canyon. Need your help spreading the word. Maybe we can help find this other individual and see if they have any information. No guarantee they live in CO, could have been a tourist passing through so please re-post.
