Pair arrested in slaying of man found dead in box

California authorities arrested two people Monday in the death of a man found dead in a box last week in downtown Las Vegas.

A task force of the FBI and Los Angeles police arrested Las Vegas residents Anthony Stiger and Melanie Costantini, both 20, on murder charges in the slaying of Harold Shilberg, Las Vegas police said.

The 58-year-old, who died from multiple "incised wounds," was found dead Nov. 9 in a garment box at the bottom of stairs at the Newport Apartments, 2540 Fremont St., near Charleston Boulevard.

Shilberg owned and lived at the apartments. Stiger lived at the complex with Costantini, his wife, and worked there as a maintenance man, according to the couple's arrest report.

When police arrived at the scene, they found Shilberg in the box next to a running U-Haul moving truck. Detectives went to the U-Haul store a half mile away and found surveillance video of Stiger earlier that evening renting a truck and buying a garment box, the report said.

Police also found large amounts of blood throughout the couple's apartment, the report said.

Stiger and Costantini were awaiting extradition to Las Vegas.
