Four men have been arrested in connection with last weekend's deadly carjacking at a mall in New Jersey, prosecutors say.

The suspects have been identified as 29-year-old Hanif Thompson, of Irvington, N.J.; 31-year-old Karif Ford, of Newark; 32-year-old Basim Henry, of Newark; and 33-year-old Kevin Roberts, also of Newark.

Investigators say Dustin Friedland, 30, was shot in the head Sunday night in front of his wife in a parking garage after shopping at the Mall at Short Hills in New Jersey. Police say two suspects then took off with his Range Rover. Friedland died several hours later.

Police found the abandoned Range Rover in Newark the following day. Investigators say "old-fashioned police work" and tips from the public allowed them to track down the suspects.

Prosecutors say it appears that Friedland was targeted specifically because the suspects were interested in his vehicle.

The four suspects are being charged with murder, felony murder, carjacking, conspiracy, possession of a weapon and possession of a weapon for an unlawful purpose. They were arrested overnight.

Three of the suspects were taken into custody in New Jersey, and the fourth was arrested in Pennsylvania, according to prosecutors.

The suspects are each being held on $2 million bail.
