Murder on mind of my cop gal pal

FBI informant John DiRubba insisted Tuesday that his jailed NYPD paramour was dead serious when they discussed killing his daughter and her spouse during secretly recorded conversations.

“There’s two people that know the truth,” said DiRubba after a brief Manhattan Criminal

Court appearance on charges of stealing a $54,000 diamond once meant for Officer Valerie Cincinelli’s engagement ring.

“It’s me and her, and I know what she wanted to do with my daughter.”

Defense lawyer James Kousouros argued at a Monday hearing that his client Cincinelli (above) was “mocking” DiRubba during the conversations he secretly recorded for the feds prior to her May 17 arrest.

“It is palpably clear that she did not give [DiRubba] $7,000 to give to anybody to commit any murders,” the lawyer said. “There was no deed that was going to be carried out.”

The imprisoned Cincinelli, 35, was charged with hiring a hit man to kill DiRubba’s 15-year-old girl and the officer’s estranged husband, Isaiah Carvalho, even allegedly offering DiRubba some ideas for murdering the high schooler: “Run her the f—k over. How about that?”

DiRubba, 54, said there was no doubt in his mind that Cincinelli wasn’t kidding around during their ominous chats.

“No,” he said while walking briskly from the courthouse. “There’s two Valeries people need to know about. There’s the good Valerie and the bad Valerie.”

DiRubba faces charges of grand larceny and robbery for the gunpoint theft of the pricey sparkler.

Asked one last time if Cincinelli meant what was heard on the tapes, DiBubba offered a one-word reply: “Absolutely.”
