Mario-Alberto Buelvas-Perez was 30 when he vanished in New York City in the winter of 2007 after completing a helicopter repair course in Virginia. He arrived in Manhattan on January 1, 2007, planning a few days in the city before returning to Colombia. He stayed in a hotel and remained in regular contact with his wife, but those communications stopped and he never returned home.

When the family reported him missing, the New York City Police Department found his hotel room intact: personal belongings, documents and gifts for his family were all left behind. The last confirmed sighting is of him leaving the hotel; no other conclusive leads have been reported and the case remains open with the NYPD Missing Persons Squad.

If anyone was in Manhattan in early January 2007 and remembers seeing Mario-Alberto or has information about his movements after he left the hotel, please come forward.
