Saw a tweet from a provider sending condolences to her family.  Another provider confirmed she passed. No details known.  

damn that is awfully sad. I am going to san fran in a few weeks and was looking forward to seeing her. I knew something was up when her site on preferred411 no longer existed yesterday.  

Wow !!  She was posting on Twitter up to 6/22 but as you noted, all of her websites are down.  Never met her but was always thinking about it as she had such consistently great reviews.  So sad and unfortunate.  Anyone have any more details?

girls on twitter are openly using her death to advertise their own twitter feed, but also keeping it a secret to make it seem more mysterious

I met with Ria many times, and she was a sweet, honest and caring person.  We met in Hawaii, SF, NYC and Boston and spent time exploring those cities.  We talked every few days and last heard from her on June 23rd as we were planning a trip to the MoMA in SF in July after her return from London and Paris.   I wish I knew what happened.  She will be missed, condolences to her family
