MOUNT HOPE, the Bronx (PIX11) — Two young boys found lifeless in a bathtub in the Bronx over the weekend died from multiple stab wounds to the neck, the New York City medical examiner’s office confirmed on Monday.

Police have charged the boys’ mother, 22-year-old Dimone Fleming, with counts of murder with depraved indifference to a person less than 11 years old in connection to the slayings, according to authorities.

First responders took Fleming into custody for a psychological evaluation around 7:20 p.m. Saturday while responding to a 911 report of her behaving erratically at a building on Echo Place near Anthony Avenue, police said. The building includes both rented apartments and city-run shelter space, officials previously said.

Police answered a second 911 call at the location about 35 minutes later and found Dashawn Fleming, 3, and Octavius Fleming-Canada, 11 months old, repeatedly stabbed inside the bathroom of the family’s unit, authorities previously said. The brothers were in a bathtub covered with clothes, as running water overflowed onto the bathroom floor. They were rushed to an area hospital, but could not be saved.

The father of the boys found them in between the two 911 calls. The officers who responded to the initial 911 call didn’t see them, authorities said.

“This is an incredibly heart-breaking and shocking tragedy,” a spokesperson for the city’s Department of Social Services said in a statement to PIX11 News. “We offer our deepest condolences to all who have been impacted and stand ready to provide them with any support they need during this incredibly difficult time.” 

As of early Monday, Dimone Fleming remained at the hospital where she had been taken for a psychological evaluation. Police told PIX11 News she would likely be there for some time.
