GREAT MOMENTS IN TIMING: Horrific video shows suspect watching woman burn to death in F train car after he allegedly set her on fire.

A migrant from Guatemala has been arrested for allegedly lighting a sleeping subway rider on fire in Brooklyn on Sunday morning — then watching as his innocent victim burned to death in what the New York’s top cop called “one of the most depraved crimes one person could possibly commit.”

The savage killing — which happened at about 7:30 a.m. on an idling F train at the Coney Island-Stillwell Avenue station — shocked commuters, MTA workers and NYPD Commissioner Jessica Tisch, who said Sunday that the heinous crime “took the life of an innocent New Yorker.”

“As the train pulled into the station, the suspect calmly walked up to the victim, who was in a seated position at the end of a subway car … and used what we believe to be a lighter to ignite the victim’s clothing, which became fully engulfed in a matter of seconds,” Tisch said at a press conference.

Patrolling cops smelled and saw the smoke, then found the flame-covered woman, the commissioner said.

They extinguished the blaze, but the woman died at the scene.
