He wants her to pay — in cash — for his sins.

Kenneth Moreno — the lead defendant in the Manhattan “Rape Cops” trial — is now hitting his ex up for more child support for their 14-year-old daughter, of whom he has custody.

“OK, he lost his job now — but why should I have to pay for what he did?” the disgusted ex-girlfriend, Maria Cruz, told The Post.

“He’s just being spiteful. He’s angry,” claimed Cruz, 35, a city bus driver from Staten Island.

The ex-cop made the demand for cash on May 27, the day after he was acquitted of rape but convicted of official misconduct and fired by the NYPD, according to court documents that Cruz shared with The Post.

“He didn’t waste any time,” Cruz said.

The ex said she lost custody of their daughter in 2004, when she didn’t have a job and lived in a one-bedroom apartment.

Moreno cited a change in his personal finances in seeking an unspecified bump in the current $50 a month Cruz gives him.

Still, Cruz may get the last laugh.

The warring pair’s next child-support hearing is set for June 29 in Family Court in Brooklyn — the day after Moreno is scheduled to be sentenced in Manhattan Supreme Court on the three official-misconduct raps. He faces up to two years in jail.

Moreno’s three convictions are for each of the three visits he made to his accuser’s East Village apartment.

Cruz had sole custody of their daughter until she was 7 and has been seeing the girl once or twice a week since then, she said.

Court papers provided by Cruz catalog an extended, ugly custody battle, during which a shrink and two judges at various points agreed that she was a fit mother and should be the custodial parent.

Then, in April 2002, one of those judges ordered Moreno to pay more than $700 a month plus $6,000 in support arrears, court papers show. Cruz said that soon after, Moreno started fighting her for custody of the child.

“He got an expensive lawyer,” Cruz said of losing custody. The Post is withholding the girl’s name because of her age.

Moreno’s lawyer, Joseph Tacopina, says Cruz lost custody of the girl for legitimate reasons.

Cruz has known Moreno since they started dating when she was 18. She kept her silence last month as Moreno portrayed himself on the witness stand as someone who cares deeply about the well-being of women — but the child-support bid has forced her hand, she said.

By 2000, Cruz and Moreno had called the cops on each other six times over violent altercations — enough that the NYPD’s Internal Affairs Bureau temporarily took his three guns in October of that year, according to police and hospital records.

Hospital records from 1999 document one instance where Cruz was taken to Lutheran Medical Center in handcuffs when Moreno had her arrested after an argument. She was treated for bruises and scratches on her face and arm.

“He knows the law” — and its limits, she said.
