BURLINGTON, Vt. – Burlington police are searching for two persons of interest in connection with the fatal beating of a transgender man at a homeless encampment in the Vermont city.

Investigators seek to question 21-year-old Erick Averill and 23-year-old Myia Barber, two transients living in Burlington, about the May 22 attack on 38-year-old Amos Beede.

Beede was found unconscious suffering from facial fractures, a subdural hematoma and broken ribs near the Barge Canal on Pine Street. Lt. Shawn Burke says the victim had a tent at the homeless encampment.

Beede died of his injuries Sunday at the University of Vermont Medical Center.

A hate crime hasn’t been ruled out as a possible motive for the beating, although investigators say bias doesn’t appear to be a primary factor in the fatal attack so far.
