An elderly Holocaust survivor who was allegedly beaten to death by a 95-year-old dementia patient at a Coney Island nursing home was a beloved grandmother who put family first, her daughter said Tuesday. 

Nina Kravtsov, 89, was mortally injured when the unidentified fellow resident of Seagate Rehabilitation and Nursing Center bludgeoned her with a metal wheelchair piece just after 10 p.m. Sunday, according to cops and law enforcement sources.

Kravstov – found lying in bed with a bleeding head wound – was rushed to NYU Brooklyn Hospital, where she was initially listed in critical condition, cops and sources said.

She died from her injuries early Monday, cops said 

“I was devastated,” daughter Lucy Flom told The Post. “My friends are saying they can’t believe it because it only happens in movies.

“Right now I’m grieving….the circumstances of how [my mother] died,” Flom, who lives in Florida, said. “I said, OK, they took her to the hospital. They are going to stabilize her. She was in the trauma unit. I didn’t expect this outcome that she’d die.

She said her mother was a Holocaust survivor who lived in Ukraine before moving to the US and settling down in Brighton Beach with her husband — always sacrificing for others.

“She was 5-years old when she was in the ghetto,” Flom said. “She had a big family. She lost most of her family.”

Kravtsov launched a nursing career in Ukraine, where “everybody loved her,” and she was also a teen mom, her daughter said.

“She sacrificed a lot. She was a single mom. She had me when she was 18,” Flom said. “She came here to give me a good education,” she added. “She was a very dedicated mother.”

“She was a nice lady. She was like many moms – very loving, caring, devoted.”

Flom said her mother later remarried as the daughter gained a stepbrother and stepsister.

“She was a mom to all of us,” Flom said. “We are just grieving.”

Kravtsov also had many friends in Brighton Beach – where she lived for years – some of whom have since passed away, her daughter said.

“They all loved her,” Flom said. “I loved her, too.”

Kravtsov moved to the nursing home about 5 years ago after the death of her husband — and remains a beloved figure by her former longtime neighbors. 

“She lived here for a very long time,” one resident said. “When her husband passed, she was living alone and her daughter took her to the nursing home.”

Another former neighbor, who identified herself only as Katya, recalled Kravstov as “very friendly and very sweet.

“She’d sit by the window and we’d say, ‘Aunt Nina.’ Everybody called her Aunt Nina. She’d wave. We’d ask how she was doing,” Katya said. “We were hoping that she’d come back.

Following the deadly attack, the older senior was taken to Coney Island Hospital for both a physical and psychiatric evaluation, sources said.

She remained at the hospital Tuesday as cops conferred with the Brooklyn District Attorney’s Office about what – if any – charges she should face, the sources said.

The wheelchair piece she allegedly used in the brutal attack was lying on the pavement just outside the facility behind blue crime scene tape Monday afternoon.

Flom said her mother’s funeral will be on Friday. Details of the services were not immediately available.
