A toddler who was beaten in a Brooklyn foster home was taken off life support on Friday.

Kymell Oram, who was 18 months old, died at Brookdale University Hospital on March 28 of blunt force trauma — and his death was ruled a homicide, the city's medical examiner said.

Oram was hospitalized with broken ribs, damage to his lungs and lacerations on March 17.

Prosecutors said the mother's boyfriend, 19-year-old Kysheen Oliver, beat the child while the foster mother was away. He is facing second-degree assault charges, but the Brooklyn District Attorney's office says it's possible the charges could be upgraded now that the child has died.

Oliver's attorney could not be immediately reached for comment.

The foster mother has not been charged in the case.

In a written statement, the Administration for Children's Services said it's looking into the foster care agency responsible for monitoring the home: "ACS continues to investigate this tragic incident, the agency involved, and all aspects of the care of this little boy," the statement read.

ACS has been under scrutiny and just announced reforms spurred by the death of a 4-year-old who died last September while under the supervision of city caseworkers.
