Family and friends of Dr. Michael Roth, a veterinarian in Richmond, are concerned that he might be missing.

 The first report of his possible disappearance was posted by Dan Valenti, a regular contributor to The Pittsfield Gazette. In his blog Planet Valenti, he put out a plea asking anyone who knew of Roth's whereabouts to call the state police barracks in Lee or to contact Valenti himself. According to police, Roth's elderly parents, who live in Kinderhook, N.Y., were worried because they had not heard from their son in nearly a week.

As of this Tuesday morning, according to state police in Lee, no one has filed a missing person case on Roth's behalf.

Several calls made to Roth's house this morning went unanswered.

Michael Roth has a mobile medical practice and is affiliated with the Animal ER of the Berkshires as well as the Berkshire Veterinary Hospital.

 Several photos of him can be found at his Meetup page, where he describes himself as a "vegan veterinarian living just over the NY line in Richmond." According to his profile there, he belongs to several vegan groups as well as the Berkshire Enthusiasts through which he signed up last week for a Moonlight Snowshoe Trek this Thursday night, Jan. 20, at the Arcadia Shops.

 If you have any information as to his whereabouts, contact the state police barracks in Lee at 413-243-0600 or e-mail Valenti at danvalenti@verizon.net.

As of Thursday, repeated calls to Roth's home have gone unanswered.
