Video captures police scouring the area overnight near the apartment building on Howard Avenue in Brownsville where 11-year-old Jacob Pritchette lived.
Investigators executed a search warrant at the building, but there were no signs of the boy in the apartment, the backyard or the dumpsters behind the building.
According to the NYPD, someone called ACS on Wednesday to conduct a wellness check on Pritchette, who has autism.
Once officers arrived, they searched the home but did not find the boy. Officials, however, determined there was no electricity in the apartment while an NYPD K-9 cadaver dog got a hit on the refrigerator for human blood.
Police later took a 50-year-old woman believed to be his mother into custody. At the time, ACS recovered a birth certificate with the woman as the listed mother. The woman had initially denied being the child's mother.
Sources say the boy has never attended public school, while neighbors tells Eyewitness News they haven't seen him in weeks.
"I would always see a little boy in the window playing with his toys by himself making noise, and since all of this has taken place, I realized to myself like, the boy is not in the window no more. I haven't seen him like all summer," said Crystal Burrell, a neighbor. "All summer, he has not been in the window, so it's a sad situation."
As of Friday morning, Prichette's mother was taken to the hospital for evaluation.
