Man 'slaughtered entire family of gran, mom and two children in Brooklyn bloodbath knife frenzy'

A man has been detained after an entire family was butchered including a grandmother, mom and two children in the family's Brooklyn apartment.

The New York Police Department says it has taken a man into custody in connection with the deaths. Officers rushed to the scene on Friday in response to a report of an assault. The horrified police found the oldest victim dead with multiple stab wounds. Police identified her as Fayzieva Mavlyuda, 56, and said she was the grandmother of the two youngest victims.

The NYPD did not specify the injuries of the other three victims found dead in the home: Maftuna Khakimova, 27, and her two children; Kamila Shavkatova, 5, and Timur Shavkatov, 4. Police identified the same Bensonhurst neighborhood home address for all four of the victims.

NYPD officials declined to detail who reported the attack or what relation they had to the family, but a family member said it was the children's dad who made the grim discovery, CBS New York reports.

The name of the man in custody, aged 24, was not immediately released. Police said he was being investigated and processed, but he had not been arrested as of Saturday morning. Witnesses saw Maftuna Khakimova's brother-in-law arrested, who lived at the apartment.

"He's just like, 'I have nothing left. [The suspect] took everything. My two kids, my wife, my mother. He took everything,'" the family member said. "It's just very tragic, very heartbroken, sad, a lot of grief."

The family arrived from Uzbekistan in 2007, reports suggest.

Neighbor Juan Perez was jolted awake by the sound of inconsolable weeping outside his bedroom window across the street in the early hours of Saturday morning.

"There was a man here who, mainly they were trying to console because he just couldn't stop sobbing. Although it was multiple of them, but he must have been the closest to the family," Perez recounted.

"I just saw all the cops pulling up last night, and I heard somebody screaming," said Jennifer Ponzi, another local resident.

"The son was screaming his mom is dead," disclosed an additional neighbor.

A long-standing neighbor mentioned that the family has resided in the building for roughly ten years. This neighbor, along with her mother, also originated from Uzbekistan and had a friendly relationship with the 56 year old grandmother.

"She always helped me. When I came 10 years before, she always helped me," the neighbor expressed with gratitude.

"I can't imagine how he feels now because I have kids. I have kids," Patricia Carreno, a fellow neighbor, empathised.

"It's big tragedy for everybody, for neighbors, for family. This is unbelievable," lamented another neighbor, reflecting the community's shock.

Detectives dedicated their Saturday to meticulously combing through the apartment building, knocking on doors to gather rinformation from neighbors.

Outside the apartment block on West Eighth Street, a growing memorial adorned with flowers and candles stands as a poignant tribute.
