The ice-blooded murderer of a beautiful exotic dancer will stay put in prison, a state appeals panel ruled today.

Paul Cortez had been easily convicted, in 2007, of slashing the throat of ballerina-turned-stripper Catherine Woods after investigators found his handprint in the victim’s blood on her bedroom wall, right over her body.

Cortez had argued, grotesquely, that the blood was menstrual blood and was there from a previous encounter.

In rejecting his appeal, the appellate panel wrote that there was “overwhelming evidence of guilt,” and that Cortez’s complaints about his lawyers, prosecutor Peter Casolaro and Manhattan Supreme Court Justice Carol Berkman were unfounded.
