NYPD officials said officers arrested Lower East Side resident Christian Millet around 9 p.m. Wednesday in connection with the death of Edwin Echevarria, 65, whose torso was found last week after a ferry crew spotted the suitcase in the river near Governors Island. Both men lived in the same apartment at NYCHA’s Baruch Houses, according to police.

The NYPD has arrested the roommate of a man whose dismembered body was found floating inside a suitcase in the East River last week—after the two had been fighting about food, sources said.
