Radiator tot-death horror

A baby girl suffered fatal burns when she fell off a bed and became wedged next to a radiator yesterday — her first birthday — while visiting her grandma in upper Manhattan, authorities said.

“[It] was her birthday . . . Her grandmother was planning to have a party for her,’’ said Steve Alvarez, the stricken uncle of tragic Gabriela Grimes of Albany.

The city’s Administration for Children’s Services is investigating the early-morning incident at grandmother Lourdes Carrion’s West 110th Street apartment.

Carrion, 60, told cops she had put Gabriela to bed Monday evening, and she was fine when Carrion checked on her at 2 a.m. The tot’s sister, Lourdes, 3, also was sleeping in the room.

But the grandmother said that when she went in again at 6:15 a.m., she discovered that Gabriela had fallen off the bed and gotten trapped against the scorching radiator, sources said.

The little girl had severe leg burns and was in cardiac arrest, officials said.

“I heard sirens, and I ran downstairs’’ to see an EMS worker performing CPR on the tot, said neighbor Diane Johnson, 55.

Gabriela was pronounced dead at St. Luke’s Hospital.

“Obviously, the mother is upset, she’s devastated,’’ said Alvarez, talking about his sister, Lilibeth Grimes. “There’s nothing you can say to console her. It was her baby.”

Alvarez said he talked to Carrion and she told him only that Gabriela “fell off the bed,’’ before the woman became too distraught.

Police said no criminality is suspected.

It’s unclear why Gabriela was not in a crib.
