A “psychic” swindler preyed on a lovelorn Brooklyn man for nearly two years, using his girlfriend’s death as an excuse to dupe him out of more than $700,000, officials said Wednesday.

Pricilla Delmaro had warned her 30-year-old client that his relationship with his girlfriend was threatened by evil spirits, and that it would cost him a lot of money to remove them.

So, when his girlfriend died unexpectedly, Delmaro — who was using the alias Cristina Alvarez — convinced him that the death was no coincidence, and continued to squeeze him for more money to keep the spirits away from anyone else in his life.

Delmaro, 24, and her partner and husband, Bobby Evans, 25, were arrested Tuesday and charged with second-degree grand larceny. They were each being held on $250,000 bail.

Delmaro/Alvarez had instructed her patsy to wire more money into the account of Evans, whom she described as “an assistant” in her “church.”

Eventually, the well-to-do marketing executive became suspicious of the fortune teller, and did some research that led him to a private investigator, Bob Nygaard, who specializes in psychic scams.

“He started seeing someone new, and the psychic began concocting new problems,” Nygaard said. “He started noticing some discrepancies.”

Nygaard said he recognized Evans’ name from a previous investigation. Nygaard had helped cops in Florida bust Delmaro a few years ago on a similar scam, but by the time he got involved in the Brooklyn man’s case, Delmaro had disappeared and the victim was out $713,975 in cash and jewelry.

“Once someone gets caught in their webs, these psychics are very cunning and ruthless, and defraud these people out of their life savings,” Nygaard said.

The victim, who did not want to be identified, stumbled on the cunning fortune teller two years ago while trying to clear his head during a walk through Times Square.

He gave her $2,500 for an initial reading at a West 43rd Street psychic shop.

On Tuesday, Nygaard got a tip that Delmaro and Evans were dining at a 6th Avenue steakhouse, and called detectives who were investigating the case.

“It’s very lucrative,” Nygaard said of the scam. “They were living the high life off the victim’s money.”
