A man’s head and torso were found in a garbage bag in a Brooklyn dumpster on Friday morning, prompting a murder investigation. The discovery near E. 21st St. and Ditmas Ave. followed reports of a foul odor and recent arguments heard from a resident on the sixth floor. Authorities believe the victim lived in the building and are searching for a roommate, possibly his boyfriend, who may be a person of interest. The medical examiner will determine the cause of death. No arrests have been made, and the case remains active.
