A Maryland woman died after receiving butt injections in a Queens basement by a quack doctor who fled the scene, police said Tuesday. Kelly Mayhew, 34, succumbed to the botched procedure after driving with her mother to Far Rockaway from Maryland on Saturday.

“Her death just came out of nowhere,” said family friend Kem Harris. Mayhew’s doomed trip to New York ended in a basement apartment in a two-family home on Dickens St. that doubled as the phony plastic surgeon’s office.
