12-Year-Old Pleads Guilty To Shopping Cart Assault That Critically Injured UWS Woman

MANHATTAN -- One of the 12-year-old boys accused of pushing a Target shopping cart off the upper level of a Harlem mall last month, critically injuring an Upper West Side philanthropist and real estate broker, pleaded guilty to the tragic assault Friday.

The boy, who turns 13 Saturday and whose name is being withheld by DNAinfo, faces up to 18 months in juvenile detention at sentencing on second-degree assault charges for the attack on Marion Hedges at the East River Plaza Mall. The sentence could be extended indefinitely until he reaches the age of 18.
