MOUNT HOPE, the Bronx (PIX11) — Two young boys were fatally stabbed in a Bronx apartment Saturday night and their 22-year-old mother was named a person of interest in the horrific ordeal, authorities said.

The 11-month-old and 3-year-old victims were found with multiple stab wounds to the neck and body in the bathroom of an apartment at Echo Place in Mount Hope at around 8 p.m., police said. The brothers were discovered in the bathtub covered in clothes with the water running and overflowing onto the bathroom floor, according to police. They were unresponsive and not breathing.

The father and two officers tried to give the children CPR, but they could not be saved. The boys were taken to the hospital, where they succumbed to their injuries, police said.

“I heard the father screaming in the hallways, ‘Help me! Help me!’ That when he brought the two boys, lifeless, covered in blood,” said Shannon Holifield, a neighbor of the family. “It’s horrible…I’m not going to be able to sleep tonight…it’s very sad.”

About 40 minutes prior to the tragic discovery, police were called to the same apartment, described by authorities as a family shelter, for reports of an emotionally disturbed person and found the young mom acting erratic and trying to burn items, according to the NYPD. They found the woman on the third floor and took her into custody without incident. She was transported to a hospital, police said.

Shortly after, the father found the boys dead in the bathtub, and police were called to the apartment for a second time, authorities said. The cops did not see the kids during the first call to the apartment, police said.

“Patrol officers returned to the apartment, where they found an 11-month-old baby boy and a 3-year-old male unresponsive with multiple stab wounds about the body,” NYPD Deputy Chief Louis De Ceglie said.

The mother remained in police custody but has not been arrested, as of Sunday afternoon.

The medical examiner will determine the cause of death. The investigation is ongoing.
