The fire ignited just before 4:30 a.m. on Oct. 13, tearing through their small home in Logan Heights with at least five members of the Romero family still inside.

Wilber’s father, Jose Antonio Romero, 44, turned up dead inside the home.

His mother, Nicolasa Mayo, 46, died in the hospital, as did his sister, Iris “Krystal” Romero, 21 — following a heroic attempt to use her body as a human shield — to protect her younger brother, 17-year-old Angel Romero, from being burnt, relative Tania Flores told KNSD.

Iris had become brain dead and was pronounced dead on Wednesday night, police told the outlet.

Angel and his sister, Wendy Romero, 24, are expected to recover from their injuries. Wendy had tried so hard to escape that she broke her fingers beating on the door, the San Diego Union-Tribune reported.

Wilber reportedly escaped unhurt.
