Police are investigating the death of a three-month-old baby in the Bronx on Saturday night.
Officers responded to a 911 call at an apartment on Ogden Ave. and West 167th St. in Highbridge around 11:27 p.m.
Police said they found Mark Ruane unconscious.
He was rushed to Bronx Lebanon Hospital, where he was pronounced dead.
A medical examiner will determine the cause of death.
Neighbors, most of whom did not want to appear on camera, said they are familiar with the family, which recently moved into the building at 1133 Ogden Ave.
Police sources said the boy's mother is Alexondra Ambrocini. The identity of the child's father has not been released, and those NY1 spoke with in the building said they did not know his name.
"I recognize the guy," one neighbor said. "I've seen the guy before, but I've never seen him under distress. I've never seen him with a baby."
Neighbors on the floor said they did see police at the unit on a number of different occasions. They also said they heard a lot of noise coming from the apartment.
"There were some situations, like verbal situations," one neighbor said. "Everything calmed down for a while, but the police kept coming back for situations, and other agencies came and knocked on the door."
An official from the Administration for Children's Services said the agency is involved in the investigation along with the NYPD.
