A West Village man’s corpse lay unnoticed for about 25 hours outside his West 13th Street building, a longtime tenant charged.

The body of Patrick Mullins was discovered in a rear courtyard by a dog walker — whose girlfriend lives in the building — who called 911 at around 5:40 p.m. Sunday, a neighbor and police said.

“It’s a shame he was out there like that. I think it’s a terrible way for somebody to die. I hope that wherever he is, he’s found peace and solace,” tenant Cheryl Bulbach said.

Mullins had last been seen a day earlier, one resident said.

Management never informed tenants about the incident nor responded to the scene, Bulbach said.

The building super — who would have seen or heard something if on site — no longer lives on site, she added.

“If we had a super, perhaps Patrick could have been found sooner. He certainly wouldn’t have lain there dead in the courtyard,” Bulbach said.

Authorities believe Mullins, 72, jumped or fell from the six-story, 30-unit building. He lived on the fifth floor for decades.

The city Medical Examiner determined Mullin’s death was a suicide and found he died from “multiple blunt force injuries.”

“It can happen that decedents pass away some time before they are found and pronounced dead. The date of death for purposes of record keeping is the date when found,” ME spokeswoman Julie Bolcer said.

Bulbach, who has lived in the building since 1974, said Mullins had been there even longer.

At one time, he was part of a very active tenants association, she said.

Building management did not respond to a request for comment.
