Two 12-year-old punks were busted for critically injuring a woman after tossing a shopping cart off a parking garage in East Harlem, police sources said.

The boys shoved the cart from the fourth floor of the East River Plaza garage on 116th Street near FDR Drive, sending it right into Marion Hedges who was buying candy for a charity’s block party.

Hedges, 47, a real estate agent at Prudential Douglas Elliman Real Estate, was with her 14-year-old son on the ground floor of the garage when she was suddenly hit. She also has a daughter.

She was rushed to Harlem Hospital, where she’s in stable condition but remains unconscious.

The boys were charged as juveniles with assault and criminal possession of a weapon, police said. At a hearing today, the boys were remanded to the custody of the Administration for Children’s Services. A Nov. 4 arraignment hearing date was set.

One of the boy’s pals told cops about the prank and cops later arrested the duo and charged them with juvenile delinquency and criminal possession of a weapon, sources said.

The victim’s son was not injured.

“They deliberately pushed it over the edge,” a law-enforcement source told The Post.

“They’re a bunch of stupid kids, they made a bad decision. She was in the wrong place at the wrong time,” the source said.

According to a family friend, Hedges was shopping for candy at Costco for the Stanley M. Isaacs Neighborhood Center. Hedges has worked with charities 25 years and is helping at least six now.

“She is such a super, super nice person,” the friend said.

Hedges husband, Michael is flying home from Spain, where he’s head of emerging markets trading & structuring at Auriga Sociedad de Valoresworks, his father told The Post today.

When asked about Marion Hedges’ condition, Michael Hedges Sr. said, “It’s in God’s hands now.”

“It’s so hard to tell,” he added. “They have her sedated right now, she’s unconscious. It’s not quite clear what happened but I hear she has some broken bones and some cranial injuries — there’s some blood up there [he gestured to his head].

“They’re letting us up two at a time and we can only stay for 5 minutes. You can’t really see anything up there — it’s just her lying in a bed unconscious with 50 thousand tubes in her. She’s stable, they’re keeping her stable and her respiratory system is functioning.”

Of the the boys who allegedly tossed the shopping cart, Hedges said, “They should have the book thrown at them.”

He said his grandson is “holding up well — he’s a brave young man.”

The family friend added, “I’ll tell you, that is one tough kid. That little kid marched down to the police department this morning to give a statement. He’s such a tough little kid”

“They’re the nicest, kindest family,” he added.

Prudential Douglas Elliman CEO Dottie Herman said in a statement Monday, “Our thoughts and prayers are with Marion and her family as we wish her a full and speedy recovery.”

The boys face up to 18 months in a juvenile facility if convicted of first-degree assault.
