Russian police are looking for U.S. grad student Colin Madsen, 25 of Missouri (below), who went missing in Siberia on March 27th.
Madsen, who's doing his postgraduate work at Irkutsk State Linguistic University, was staying "with friends" at a remote guesthouse in Arshan when he allegedly went outdoors in subzero temperatures and vanished without a trace.
Authorities there believe he left the building early Sunday morning between 2 a.m. and 5 a.m. without an overcoat, but don't know what preceded this decision.
A colleague of the missing college student posted on Facebook this week that ‘at the moment no one can clearly explain what happened" that morning.
He also said the U.S. embassy in Moscow has been notified of Madsen's missing persons status in the mountainous tourist region of Buryatia and "are taking measures" to help locate him.
Colin Madsen is a slim Caucasian male about 5-foot-6, with blue eyes and brown hair. Anyone with information concerning his disappearance and current whereabouts should alert the Buryatian police or embassy officials without delay.
Helicopters are being deployed in today's "full scale" search for the missing young man, and his mother is said to have embarked to Russia from Jefferson City Missouri to join in the quest to find her son 'safe.'
