Troubled NYC man charged with first-degree murder in grisly slaying of four relatives, including two young kids

A disturbed Brooklyn man was slapped with multiple counts of first-degree murder on Sunday in the gruesome slashing spree that left four relatives dead — including two young children.

Shahboz Rajabboev, 24, was awaiting arraignment in the Bensonhurst bloodbath that left relatives believed to be his mother, sister-in-law and niece and nephew dead in the apartment on Friday night, police said.

Killed in the attack was Fayzieva Mavlyuda, 56, Maftuna Khakimova, 27, and the two chidren, identified by police as 5-year-old Kamila Shavkatova and her little brother, Timur Shavkatov, 4.

Police responded to the apartment on West Eighth Street on a 911 call shortly after 10:15 p.m. Friday and found Mavlyuda “with multiple stab wounds to her neck,” police said.

Cops then found the other three bodies and took Rajabboev into custody.

Law enforcement sources told The Post that the two youngsters, who were also stabbed to death, were stuffed in a laundry bag and stashed in a closet inside the apartment.

Neighbors said they heard screams coming from the apartment, unaware of the fatal outcome — and said the accused killer screamed at cops at the scene, “I’m innocent. Arrest me. It wasn’t me.”

One tenant who only gave his name as Paul said he was there when the accused killer walked out of the apartment, and not long after the father of the slain kids approached him.

“Have you seen my family,” the man allegedly said, before running back outside screaming, “My mother is on the floor, there is a lot of blood… My family has disappeared!”

Paul called Rajabboev “scary.”

“I stayed away from him. He was a big guy, aggressive, with a look in his eyes like a crazed bulldog,” he said. “You could tell something wasn’t right with him.

“He stopped smiling, stopped saying hi. I asked him if something happened, and he said, ‘Yes, something with my dad,'” Paul recalled. “He didn’t elaborate.”

According to another neighbor, the accused killer was a frequent drug user.

“When he smokes and does other things he can’t control his anger,” the man said.
