A sharpshooting retired NYPD lieutenant coolly gunned down a gun-toting career criminal who took aim at a cop while fleeing a stickup inside a crowded East Harlem pharmacy, police said.

A video captured Thomas Barnes walking from his parked Mercedes- Benz SUV at a gas station toward the suspect Thursday, crouching into a shooter’s stance and squeezing off three shots.

A moment later, suspect Wyatt (Booga) Rudolph — running about 55 feet away — collapsed from two gunshot wounds to the head. The 24-year-old gunman had $311 in his pocket, the apparent cash proceeds of the robbery.

“I’m just glad to be alive,” Barnes said afterward. “I’m glad to be home with my family

The 48-year-old NYPD vet retired in 2005 after 21 years on the job. He never fired his weapon on the job. No charges will be filed against Barnes, police said.

Barnes “really saved the day,” said BP security consultant Raffi Nakashian, who reviewed video of the shooting. “He nailed the guy.”

A half-dozen customers — including an infant girl in a stroller — cowered in fear as Rudolph jumped over the counter of the RX Center Pharmacy with his gun drawn at 11:03 a.m.

He and a sidekick made very specific demands: All the cash and 30 milligram pills of Oxycontin and Percocet, said Browne.

Three minutes later, Rudolph was lying dead in a pool of blood on First Ave. as a woman howled, “It’s my nephew!”

The killing ended a local crime wave, with the dead man suspected in four earlier pharmacy hold-ups in East Harlem and the South Bronx, police said.

Rudolph was on the street for his recent spree despite his purported role in a pair of shootings where the victims miraculously survived.

In April 2011, authorities said, the Bloods gangster shot a man six times in Sandy Springs, Ga. — just three months after Wyatt’s release from a New York prison for a parole violation.

Rudolph was also a suspect in a May 2010 shotgun shooting where a Harlem victim survived 25 pellets to the face and back.

Rudolph, who was wanted but never charged in the shootings, also had 11 New York City arrests on charges from drug dealing to assault to resisting arrest.

Both his father and uncle had violent deaths, family members said. His father, who had the same name, was killed in a drive-by shooting in East Harlem in 1992, and his uncle, Dario Diodonet, fell to his death off a roof while being chased by cops in 1995, they said.
