The estranged boyfriend of the Bronx woman killed when she and her infant daughter were pushed off their 15th-floor balcony is now wanted for her murder.

Angel Carrasco, 31, should be considered “ARMED AND DANGEROUS,” according to an NYPD wanted poster.

The shocking slaying, the climax to a acrimonious relationship, happened 3:38 a.m. Tuesday when Nathaly Ramirez, 23, holding her 8-month-old daughter, slammed into the ground outside her Allerton building on Olivnville Ave. after she was thrown from her balcony, police said.

Surveillance footage obtained by the Daily News shows Carrasco, wearing a tan hoodie with the hood up and a backpack, walking slowly away from the scene with his head down about 3:45 a.m. — just as an ambulance and a police car arrive with flashing lights and sirens.

Carrasco is described as 5-foot-9 and 150 pounds with blue eyes and brown hair.

Police rushed the infant to Jacobi Medical Center, where she is listed in critical condition.

Her mother, taken by medics to the same hospital, could not be saved.

An upstairs neighbor recounted Ramriez’s final minutes, arguing with a man police say is her estranged boyfriend a short time before she was killed.

“They were both on the terrace,” said Nancy Morales, 69. “She was holding the baby. She told him to leave her alone. She was telling him, ‘Stop! You’re scaring the baby!’

“He said, ‘You want me to do it? You want me to do it?’ I just said a prayer and went to sleep.”

A 23-year-old woman was killed and a baby girl was critically hurt in a plunge from a 15th-floor balcony (circled) in an apartment building on Olinville Ave. in the Bronx early Tuesday, Oct. 6, 2026.

Ramirez went to Bronx Leadership Academy before studying psychology at Baruch College, according to her LinkedIn page. She also interned at Lishawn’s Consulting, a Brooklyn-based business management consulting company.

“It is such a loss for my team and I,” said Lishawn Alexander, owner of Lishawn’s Consulting. “Words cannot truly express my sorrow. Ms. Ramirez was a team player in its truest sense.”
