Maniac accused of killing 4 relatives, including 2 kids, inside NYC home left building with bloody face, claimed he was on ‘shrooms’: DA

The crazed relative accused of slaughtering four family members inside a Brooklyn apartment claimed he was high on shrooms after he allegedly stabbed his mother, strangled his sister-in-law and her two small kids and fled the home with a bloody face, prosecutors said Sunday.

Shahboz Rajabboev — who is facing murder charges after his brother discovered the gruesome crime scene Friday night in Bensonhurst — claimed to police he didn’t know what happened to his relatives, including his niece, 5, and nephew, 4, because he ingested mushrooms, according to the Brooklyn District Attorney’s Office.

During Rajabboev’s arraignment Sunday night where he was ordered held without bail, Assistant District Attorney Tziyonah Langsam said a confidential witness who had just returned home saw the 24-year-old suspect “exit the location with blood on his face.”

“The witness went into the location and observed the defendant’s mother on the ground with stab wounds to the neck and body,” Langsam said of 56-year-old victim Mavlyuda Fayzieva.

While the witness called 911, Rajabboev — who was dressed in a white disposable coverall during his court hearing — bizarrely called authorities to tell them about dead bodies inside the home as well, Langsam said.

When first responders arrived, they found three more victims, Maftuna Khakimova, 27; Kamila Shavkatova, 5; and Timur Shavkatov, 4, inside the home wrapped in garbage bags, the prosecutor said.

The children’s bodies were stuffed inside a closet, while Khakimova’s body was wrapped in a blanket and a trash bag on the floor, according to the criminal complaint.

While prosecutors didn’t identify the witness, neighbors told The Post Saturday that the suspect’s brother, who was married to Khakimova and the father of the two children, walked into the bloody scene.

Rajabboev told police in a video statement “he doesn’t know what happened. That he took two grams of shrooms,” Langsam said during the arraignment hearing.

One neighbor told The Post Saturday that Rajabboev was known as “narco-man.”

“Very good family. They live together. Mother, father, two sons, who are brothers, and the brother’s wife and their two kids,” the woman said. “Very good family. But everyone knew him. He is a narco-man.”

The defendant is facing four first-degree murder charges and four second-degree murder charges.

Rajabboev was sent to jail ahead of trial. He was previously arrested in 2023 for misdemeanor assault before that was dropped to adjournment in contemplation of dismissal.

His lawyer, from the Brooklyn Defender Services, did not comment, though Rajabooev claimed to cops he was innocent before he was taken into custody, another neighbor previously told The Post.
