A Queens woman accused of flying into a jealous rage and torching her ex-boyfriend — killing him and three others — was found not guilty on all charges yesterday.

It took the jury a little over five hours to clear Agnes Bermudez — and most of that time was devoted to rehearing testimony and reviewing a grisly video of Bermudez and her ex, William Salazar, running ablaze from his Middle Village apartment on Father’s Day 2008.

Bermudez raised her hands to her mouth and then lowered her head to the defense table in relief after the verdict.
