THE BRONX, N.Y. (PIX11) — The body believed to be a 2-year-old boy who disappeared last month was found in the water in New York City, sources said.

Little Montrell Williams was last seen May 10 at his grandmother’s house in the Bronx, according to police and the family.

The NYPD Harbor Unit found the body near College Point in Queens, and investigators are waiting for Bronx detectives to identify the body, sources said.

NYPD divers had been searching the Bronx River since Monday. The boy’s father, Arius Williams, was caught on surveillance video throwing a bag, possibly with the child inside, into the river, sources said.

“Seeing the crime committed on the video was heartbreaking, but he is off the street, and he will have his day,” NYPD Chief of Department John Chell said.

“Our hearts go out to the family,” he added.

Williams told the boy’s mother over the weekend that he had thrown their son into the Bronx River. He also told his mother, Sabrina Williams, the boy was still alive.

“He good. He good. Don’t worry about it,” the father told his mother over the weekend.

The grandmother said she was heading to the river on Wednesday to grieve her grandchild.

“He’s gone,” she said.

Montrell’s 17-year-old mother had not seen her son since May 10. Two days later, she went to family court to report that her son was missing, but a warrant was not issued, sources said. She went back a second time pleading for help, but the outcome was unclear because the records are sealed.

The mother then followed Williams after he got on a Manhattan-bound train and pressed him about their child, sources said. Williams, who was previously arrested for beating up the teen, then allegedly pulled a knife on her during the encounter, sources said.

Williams was arrested and held at Rikers Island for custodial interference.

The child’s grandmother told NewsNation affiliate WPIX she had warned police about Montrell’s disappearance, but was told it was legal because Williams was the father.

“My son kidnapped my grandchild out my house,” she said she told police in an interview with WPIX on Tuesday.

Her son left with Montrell after a fight at a Mother’s Day gathering at the grandmother’s home. She begged him to bring the child back before going to the cops on May 11.

Sources said detectives believe the boy was not alive when the grandmother went to police to file a missing person’s report because the dad arrived at a family member’s home May 11 without Montrell.

NYPD Commissioner Jessica Tisch said Wednesday the department is investigating how the family’s missing report was handled.

“The NYPD takes any case of a missing person very seriously,” Tisch said on “Good Day New York.”
