The death of a baby girl in Claremont has been ruled a homicide by police.

Police say 1-month-old Monreaux Mercado was found unconscious inside a Webster Avenue apartment Tuesday. They say she was taken to Bronx Lebanon Hospital, where she was pronounced dead.

The medical examiner says the baby died from an injury to the head.

News 12 spoke to a person who lives in the same building, who says the baby belonged to a house guest of the woman who lives in that apartment.
