Mom tossed 1-month-old from fourth-floor window

The boy, just 20 days old, was found around 4 a.m.in a courtyard outside the 115th Street building near a trash can, in the Richmond Hill section.

Ilyayeva said she saw the family leaving with the police.

A spokeswoman for the city medical examiner says Friday that 1-month-old Rizwan Ahmad died of blunt impact to the head and torso.

The neighbor, Mazol Ilyayeva, told the Daily News of New York said the father asked: “Did you hear my baby cry when she threw him out of the window?” The boy also suffered liver and spleen injuries.

“This a truly horrific and disturbing case of a mother accused of killing her helpless infant son”, said Queens District Attorney Richard Brown.

Chowdhury was taken to Jamaica Hospital Medical Center for a psychiatric evaluation Friday because she was acting strangely, the police said, and then taken to a station house for questioning.

Chowdhury has two other children around the ages of 2 and 8, said sources. It was not immediately clear how they were related to Chowdhury.

A total of four adults and two other children were in the apartment at the time the baby was allegedly thrown out the window by his mother. No one else has been charged.

If convicted of murder, Chowdhury faces up to life in prison.

A 21-year-old woman who confessed to throwing her 3-week-old son out of a bathroom window told police that he was possessed by evil spirits, according to court papers filed Monday.
