Police are looking for Frederico Bruno (inset top right) in connection with the aggravated assault on two women in Jersey City.

NBC New York – A manhunt is underway for a suspect who allegedly attacked his ex-girlfriend at her Jersey City home and forced her out a third-floor window while she was holding her infant in her arms Friday morning, police tell NBC 4 New York.

Both the 20-year-old mother and the 3-month-old baby are hospitalized in critical condition, police said. Police say Frederico Bruno, 19, had a key to his ex-girlfriend’s apartment and had been hiding inside, waiting for her to get home. When she returned with her baby, who is also the suspect’s child, and a friend, Bruno allegedly attacked her.

The 21-year-old friend threatened to call 911 and Bruno allegedly turned on her, slicing her up with a household cutting device and leaving her for dead, police said. Then the suspect ran down the fire escape and, with a table, continued to assault the mother of his child, who was lying on the ground on top of her baby after the two plunged three stories out the window, police said.

It wasn’t immediately clear if the suspect pushed his ex-girlfriend out the window or if she leaped out of it in a desperate effort to escape him.
