The man accused kill 20 year old ex-girlfriend when she pushed their baby in a stroller on the Upper East Side was sent to jail without bail on Saturday for a crime prosecutors called a “premeditated execution.”
Isaac Argro, 22, was charged in Manhattan Criminal Court on Saturday night with second-degree murder and second-degree weapon possession when the victim’s mother and sisters were accused of being Azsia. Johnson was distraught.
Johnson, 20, was shot in a clearing near Lexington Avenue and East 95th Street on Wednesday as she pushed her 3-month-old baby in a stroller to meet Argro, who recently tried to get back with health care staff good marks after months of abuse and intimidationpolice and family members said.
Argro wore black and a ski mask as he paced back and forth while waiting to kill his estranged girlfriend, Assistant Manhattan District Attorney Brittany DeCesare told Judge Eric Schumacher.


“This case can only be described as a premeditated execution. The defendant persuaded the victim to meet after work and under the guise that he wanted to give the deceased items to their 3-month-old daughter,” DeCesare said, as the victim’s mother, Lisa DeSort, began to cry bitterly.
“The defendant shot and killed the mother of her child from the void in the head, causing the 3-month-old baby to cry. [daughter] in the cart as he ran away,” the prosecutor said.
After committing the gruesome murder, Argro phoned Johnson’s family and asked where his child was while threatening that another unidentified person would be “next,” officials allege.
“To bail their honor, people are asking for the defendant to be removed. This case can only be described as a premeditated execution,” DeCesare told the judge.


After Schumacher sent Argro to prison without bail, the suspected killer asked the court to protect custody and medical care.
He will return to court on July 7 and faces 25 years in prison if convicted.
“I thought I could be stronger than I am, but I had a little bit of a breakdown because this was the first time I actually heard what was really happening in chronological order,” said Lisa DeSort told The Post after court.
“Honestly, I wanted to jump up and scream, ‘coward,'” she explained. “‘You’re not a man, you’re a monster.” That’s what I wanted to scream.”

DeSort says her daughter’s alleged killer was a gang member who wanted to be her family nicknamed “Angry Bird”.
“I honestly give you permission to enter my house. I don’t allow people into my house. I tried to treat you like a son. I want you to be a part of my daughter’s life. But you cannot be a civilian. That’s all we want. That’s all my daughter wants,” she said when asked what she would say to Argro.
DeSort thanked the NYPD and Mayor Eric Adams for the city’s swift response to the incident. Argro is arrested two days after the murder at his Brooklyn apartment building, which was also inhabited by members of the slain woman’s extended family.


However, the grieving mother blamed the city for ignoring complaints of abuse and stalking of her daughter. At a point when Argro threatened to kill DeSort, a domestic abuse counselor dismissed the comment as “freedom of speech,” she claimed.
“I am very disappointed in Queens. When my daughter reached out her hand she was abused and assaulted, this is documented. She approached and I was contacted several times with threats and stalking… we were pushed and pushed away. “DeSort said.
Johnson’s 3-month-old baby girl and another young child are in the care of family members.
“The baby is perfectly fine and in wonderful hands,” DeSort said, through a wide smile. “Both babies in fact”
