OK...I don't know if I'm losing my mind...but earlier in the day, I Googled "Rihana Marzano" and I swear I saw a missing children's poster with her on it. But now I tried Googling her name again, no result. I looked at the FB page again and couldn't find any info about her hometown. Did you find any?
