Autistic victim’s kin hail hero firefighter

A 21-year-old autistic man died in the Brooklyn blaze that also claimed the life of firefighter Timothy Klein — with the resident’s stricken kin hailing the fallen Bravest as a hero to The Post on Monday.

Carlos Richards (right), who police sources said was the son of a retired NYPD cop, was reported missing by his family when flames broke out in their home on Avenue N near East 108th Street in Canarsie on Sunday afternoon, authorities said.

His body was later found in the home’s charred remains, authorities said. The young man was autistic and home alone at the time, said a woman answering a phone number listed for Richards’ mother.

“Our condolences go to the family of the firefighter who died trying to save Carlos,” a man told The Post by phone Monday, after answering the same number.

“Right now, we’re grieving for Carlos, and we share the same pain that they are feeling,’’ added the man, who did not identify himself.

On Monday, the dead man’s sister, Chloe Richards, posted a moving photo of her brother and mother on a GotoFundMe page help with funeral costs.
