Accused cop-killer Tyrone Howard was back before a familiar face Thursday — the very Manhattan judge who blew a chance to take the career criminal off the streets.

In a glaring example of “too little, too late,” Supreme Court Justice Patricia Nuñez didn’t utter a peep about the sweetheart deal she gave the reputed gang member, sentencing him to rehab instead of prison following his guilty plea to a drug charge in May.

The timing of the brief hearing couldn’t have been more poignant, coming less than two days after Howard allegedly shot Police Officer Randolph Holder dead in East Harlem.

Nuñez just noted the ex-con’s lawyer called to say he couldn’t attend the hearing, which was hastily scheduled following Howard’s arrest a day earlier for the shooting of the third-generation cop.

“In any event, I’m ordering a pre-sentence report for sentencing. This case is adjourned to Nov. 12 for sentence, and he is remanded at this time,” the judge said.

The proceeding lasted less than five minutes, most of which was taken up by Howard hobbling into and out of court with a cane.

Howard, 30, was shot in the buttocks by Holder’s partner after opening fire on the cop while fleeing a Tuesday night gunfight with a rival drug dealer in East Harlem, police said.

Holder, 33, who was shot once in the forehead, became the fourth NYPD cop killed in less than a year.

For the second day in a row, Nuñez ducked questions about letting Howard — whose rap sheet lists 28 arrests since age 13 — avoid getting locked up for selling crack in the East River Houses project.

Howard was supposed to spend 18 months in residential drug treatment but failed to appear in court Sept. 17, by which time cops say he was wanted in connection with a Sept. 1 shooting in East Harlem.

The slain cop’s stepmom, Princess Holder, told The Post that she resented the break Howard got.

“If he was incarcerated, my son would be alive today,” she said.

“[Howard] is a loser with nothing to live for. My son was of value to society. I think the entire judicial system needs to be reformed.”

Holder also said she wanted to tell Mayor Bill de Blasio and Police Commissioner Bill Bratton to bring back the stop-and-frisk program during a condolence call Wednesday, “but I was too nervous.”

One of the slain cop’s cousins, George Johnson, said Nuñez “should be fired.”

“I hope she understands that a life rests on her head,” he said.

Another cousin, Abena Johnson, 43, said, “This should be about the death penalty.”

“I’ll take my money and pay for him to get executed,” she said.

“The fifth dead police officer this year is just around the corner. This needs to be addressed now, not later.”

Ex-Manhattan prosecutor Joan Illuzzi, now the Republican candidate for Staten Island district attorney, said the “diversion court” where Howard got his break was routinely abused by defendants.

“At least a third of them are drug dealers masking themselves as addicts to get lenient treatment,” Illuzzi said.

Meanwhile, law enforcement sources said Howard claimed to have no memory of Holder’s slaying because he was on angel dust.

“He would say, ‘I’m coming down off of PCP. I’ve been using PCP since I was a kid,’ ” one source said.

The suspect also expressed “no regrets” over Holder’s death.

“Howard didn’t give a s- -t about the cop. It was all about him,” a source said.

“He was fixated on the fact that we shot him. He kept on bringing it up: ‘You shot me. You shot me.’ ”
