A 30-year-old woman and her two sons — 2 and 10 years old — were found dead in their Corona, Queens, home Sunday, police and a relative said.

The NYPD confirmed that three bodies were found around 11 a.m. at 37-17 111th Street — the Shangri-La Plaza – but didn’t release further details.

A cousin who declined to provide her name rushed to the crime scene along with other anguished relatives who waited outside the Corona building.

“We don’t know anything about what happened,” the woman told the Post. “There are no words. The children had their whole lives ahead of them.”

She said her cousin, her cousin’s husband, two sons and the woman’s parents live on the fourth floor rear apartment.

She said the family is originally from Cañar, Ecuador, but the children were born in NY.

The mother was found hanging by a cord in the closet, a police source said.

The two children were found with plastic bags over their heads, police sources said.
