At least 106 firefighters and EMS personnel responded to the fire, which started in the home’s basement and, which was put out just after 4 a.m.

Crews found two unconscious people in a first-floor bedroom and another victim in the basement, Chief of Dept. John Esposito said during a news conference.

A neighbor told The Post the son’s badly burned body remained in the basement after the fire had been put out.

“Our policy, our procedure is that when it’s a confirmed DOA that they’re left in place and it’s the medical examiner that’s charged with taking care of that,” Esposito said when asked about the victim whose body remained in the home.

“No hydrant problems thankfully at this fire. The hydrants were clear. But we do have three people who lost their lives in a fire. By all accounts that’s unacceptable to me. We’re going to do everything at the FDNY to make sure fire deaths stay low. We certainly are thinking about the family is that are affected by this,” Fire Commissioner Robert Tucker said.

FDNY officials have not yet released the names of the deceased.

Fire Marshalls are on the scene investigating.
