Mystery Of Body Parts On I-80 Solved, Police Say

WARREN COUNTY, NJ — Three men have admitted to kidnapping and killing a Newark man whose body parts were discovered sprawled across Route 80 in Warren County, state police said.

In January 2023, Mustafa Manns, 28; William Dixon, 34; and Nishir Rios‑Figueroa, 30, all of Newark, were charged in connection with the kidnapping and murder of Quadree Burch, 27, in 2022.

Five months earlier, in August 2022, Burch’s remains were discovered on the side of Route 80 East by a NJ Department of Transportation employee who had been cutting grass along milepost 16.6 in Allamuchy Township. Burch had been reported missing nine days earlier out of Newark.

Authorities launched an investigation and discovered that Manns, Dixon, and Rios-Figueroa kidnapped Burch and drove him to Allamuchy Township, where he was shot and killed on the side of the roadway.

Rios-Figueroa previously surrendered to authorities on Jan. 6, 2023, on unrelated auto theft charges in New York. He was later charged with felony murder, murder, conspiracy to commit murder, and kidnapping in connection with Burch's death and extradited back to New Jersey.

State Police arrested Manns at a residence on Lyons Avenue in Newark without incident on Jan. 19, 2023, and charged him with felony murder, murder, weapons offenses, conspiracy to commit murder, aggravated assault, kidnapping, and robbery.

William Dixon, who was already held in the Essex County Jail since Aug. 24, 2022, for threatening associates of the Burch, was charged in January 2023 with felony murder, murder, weapons offenses, conspiracy to commit murder, aggravated assault, kidnapping, and robbery.

On December 5, 2025, Dixon pleaded guilty to aggravated manslaughter, earning a 25‑year sentence in state prison.

On March 27, Manns pleaded guilty to aggravated manslaughter, receiving a 20‑year prison sentence.

On April 20, Rios‑Figueroa pleaded guilty to aggravated manslaughter and was given a 10‑year sentence in state prison.

None of the three convicts is eligible for early release, state police said.
