Police found a 13-year-old girl dead at her parents' Brooklyn apartment on Saturday morning.
Cops arrived at the East Flatbush apartment in the Glenwood Houses public housing development at around 10 a.m. Officers found Alyssa Brown in her unconscious in her bed.
Emergency respondents declared the teen dead at the scene, but investigators found no visible trauma on the girl's body.
The medical examiner's office did not respond to requests for an update about circumstances around Brown's passing by Sunday evening.
The New York Daily News reported on Sunday that Brown, who allegedly had a learning disability, was bullied at her middle school but that sources ruled out suicide and foul play as causes of death.
