A two-year-old girl named Julia died on Tuesday night after falling from a fifth-floor apartment window in the Mott Haven neighbourhood of the Bronx.
The toddler was rushed to Harlem Hospital immediately after the fall, but medical staff were unable to revive her and she was pronounced dead shortly after arrival.
According to CBS, the tragedy took place after the child managed to remove folding plastic side panels from a window air conditioner and slipped through the gap into a rear courtyard.

Police reported that the little girl fell five stories from the fifth-floor apartment into the open area behind the building after squeezing through the opening beside the cooling unit.
Window air conditioner installation
Investigators discovered that the window air conditioning unit had been installed by the toddler's parents rather than by professional building maintenance staff.
Building superintendent Jose Sosa said the appliance's plastic accordion side panels had been secured inside the window frame using only adhesive tape.
Police officers stated that the two-year-old managed to peel away the tape and push the plastic panels aside, creating an aperture large enough for her body to fit through.
Standard room air conditioning units use accordion-style plastic curtains to seal the space on either side of the chassis, but these lightweight panels offer minimal resistance if not backed by rigid window guards or mechanical fasteners.
Courtyard discovery and superintendent response
Jose Sosa was the first person to reach the rear courtyard between the two apartment buildings after the child plunged from the fifth-floor window.
Sosa said he found the little girl lying face down on the ground and could tell immediately that she was not alive.
Describing his desperate effort to help, Sosa said he felt completely powerless in front of the tragedy, explaining that a young child was lying motionless and there was nothing he could do to change the situation.
He said he had hoped against hope to detect any sign of life, but there was no sign at all.
Emergency medical personnel arrived moments later and rushed Julia across the Harlem River to Harlem Hospital in Manhattan, where doctors were unable to save her.
Family grief and mother tribute
Julia's mother, Tessa Wilcox, described the harrowing moments when she realized that her daughter had fallen through the opening in the window frame.
Wilcox said her daughter had suddenly vanished and gone out through the window, leaving her in utter disbelief at what had occurred.
She revealed that she and her partner had welcomed Julia into their lives only after she had endured multiple miscarriages, making the toddler's sudden death all the more painful.
Wilcox said her baby was gone and she had no way to bring her back, pleading with parents everywhere to hold their babies tight because one day they might no longer be there.

Courtyard memorial and father plea
In the days following the fatal fall, a makeshift memorial began to grow in the narrow space between the two residential buildings where Julia landed.
Mourners placed candles, bouquets of fresh flowers and a balloon on the pavement as family members and neighbours gathered to grieve.
The toddler's father, Chayanne Polanco, addressed an emotional appeal to all parents while trying to process the overwhelming loss of his daughter.
Polanco urged parents to hold their children tightly in their arms, to hug them and to love them constantly because nobody ever knows when their child might be gone.
He urged parents to make sure they tell their children every single night that they love them and to make sure to embrace them at every opportunity.

Police investigation and building safety
Officers from the New York City Police Department launched an investigation into the exact circumstances surrounding the fatal incident.
Authorities confirmed that investigators are currently treating the toddler's death as a tragic accident, with no evidence suggesting any criminal activity or foul play.
The incident occurred in Mott Haven, a historic South Bronx neighbourhood known for its dense rows of multi-story brick apartment buildings.
Under New York City regulations, residential landlords are required to provide window guards in units where children aged ten or younger reside, although air conditioner installations require specialized brackets to prevent dangerous gaps.
