Aissante Diallo, 3, died in her Harlem apartment on Sunday after suffocating while trapped in a sofa bed. According to the New York Post, Aissante was at home when “the bed retracted, trapping her and her 10-year old sister.” The sister managed to escape, but Aissante was “squeezed inside.” NBC 4 reports that the girls were sleeping at the time of the accident.

Two other children were also in the apartment but not in the bed.

The children were being watched by their mother’s boyfriend but it’s unclear whether he was inside the home when the accident occurred. According to police, “his story has been inconsistent.” However, police were alerted to Aissante's injuries when the boyfriend flagged down an officer on the sidewalk at some time after 6 p.m. She was pronounced dead at the scene.

Investigators are still questioning the boyfriend while waiting for the medical examiner determine the cause of the death.
