A father who allegedly pushed his ex-girlfriend and three-month-old son out of a third-floor window is expected to be charged with murder after the infant died in hospital.
After the pair plunged three levels, Frederico Bruno, of Belleville, New Jersey, reportedly climbed down the fire escape and continued beating them with a table he found in the yard as they lay unconscious on the ground.
He was found hiding in a refrigerator on Friday evening after the brutal attack which left the 20-year-old woman, who has not been identified, in a medically-induced coma.
Damien Bruno, the suspect's baby, tragically died from his injuries at Hackensack University Medical Center on Tuesday after fighting for his life for four days.
The 19-year-old currently faces 17 counts, including attempted murder and child abuse, but he is expected to face upgraded charges after investigators receive the results of the baby boy's autopsy.
