A beloved Washington Heights bakery owner shot herself in the head in front of her husband Tuesday morning amid health complications and the possibility of losing her storefront.

Shortly after Renee Mancino got to work at Carrot Top Bakery on Broadway, she put a gun to her throat and pulled the trigger, an employee at her bake shop told The Post.

“Workers heard a low ‘pow’ but didn’t think anything about it until they heard the manager screaming, ‘Help me, help me,’” said Natasha Rivera, 28.

The Broadway location’s manager and Mancino’s husband, Bob, were both with the 66-year-old baker in the basement when she fired the fatal gunshot.

Bob broke down on the street as her body was wheeled out of their successful sugar spot, blaming her death on Presbyterian Hospital.

“The landlord killed her. My wife is dead because of those co——ers,” screamed the former NYPD cop, who was married to Mancino for more than three decades.

“Thirty years don’t mean nothing. We paid rent 31 years and you have to open up negotiations? We broke our backs for 31 years. We built this business,” he said.

Bob began crying talking about his wife’s suicide earlier in the morning, saying, “My wife killed herself right in front of me because she couldn’t take it any longer.”

Mancino had double knee replacement surgery in January and was recently informed that she had cancer, Bob said. Her physical ailments paired with rent negotiations with the building’s landlord pushed her over the edge.

The Mancinos had already gone through one round of lease negotiations with the hospital back in 2010, when they tried to hike the rent $10,000 — bringing the monthly rent to $15,000.

Carrot Top has been a staple in the Washington Heights community for 30 years, serving up delicious carrot cakes and other baked goods.

Frequent customers were shocked to hear the news of Mancino’s death, remembering her as a “hard worker” with a “heart of gold.”

“She was like a mom to me,” said Rivera, who said she and the rest of the Carrot Top crew were in shock. “She always had everyone smiling. There was no sadness around that lady.”
