NYC missing child case takes harrowing turn after K9 dog detects human blood in family apartment: sources

A missing child investigation took a harrowing turn in Brooklyn this week when a police dog detected human blood near a refrigerator in the kid’s family apartment, law enforcement sources said.

The 11-year-old autistic boy — who was reported missing from the unit on Howard Avenue near Sutter Avenue in Brownsville — had not been seen by neighbors for several weeks, prompting ACS to conduct a wellness check on Sept. 25, sources said.

The boy’s mom, who opened the door, did not hand over her son’s birth certificate, but was otherwise cooperative, according to the sources.

The case workers searched the home but found no signs that the boy lived there, the sources said.

ACS workers made a second visit Wednesday, this time joined by NYPD cops, the sources said.

When police asked where the boy was, she flew into a rage and insisted that she never had a child and lived alone, according to the sources.

NYPD detectives ultimately brought a K9 dog into the apartment, which detected traces of human blood in or around the refrigerator, the sources said.

But the boy was not found in the home and the investigation is ongoing, cops said.

His mom was hospitalized as an “emotionally disturbed person,” but was not being charged criminally by Friday morning, sources said.
