Sentencing proceedings began yesterday for the younger of two boys who admittedly dropped a shopping cart onto a philanthropist at a Harlem mall — and he has long-standing issues of neglect and violent behavior, a Manhattan Family Court judge said.

Raymond Hernandez, 12, at one time pushed his school principal, Judge Susan Larabee said, reading from the boy’s records.

Raymond has six suspensions in his school history, for “taking property, physical altercations, slurs, coercion, threats, horseplay, shoving and pushing [and] physical altercations,” Larabee said.

“Apparently, nobody knew he was at the mall on the day in question,” the judge said.

Both Hernandez and his co-defendant, Jiovanni Rosario, 13, have pleaded guilty to assault for hurling a shopping cart over the fourth-floor railing at East River Plaza on Oct. 30.

At Rosario’s sentencing hearing, officials said both boys were laughing in custody after the vicious prank.

The cart struck Marion Hedges, who had been buying Halloween candy in bulk for disadvantaged children.

A lawyer for one of the boys said prosecutors have told him Hedges is in rehab with severe head injuries, and has had to relearn her name and basic functions.
