Officials say a 13-year-old had a history of troubling behavior before he helped push a shopping cart that fell on a woman from a fourth-floor walkway at a New York City mall.

A city lawyer told a judge Tuesday the boy tried to run schoolmates over on his bike, threw things in the lunchroom and hit his mother's cat.

The attorney says the boy joked around at a police precinct after his Oct. 30 arrest and expressed more concern about his sneakers than about the woman who was seriously hurt.

The boy's lawyer says the teen needs and wants counseling for his behavioral problems.

The boy was charged as a juvenile and pleaded guilty in Family Court last month to assault. His sentencing was postponed Tuesday until later this month.
