A man was holding his son in mid-November at his Palm Springs home when five people pulled up in a dark-colored sedan, he told village police.

One held the man at gunpoint and told him to "run the chain," the man told police. The suspect then ripped the chain necklace off the man’s neck, the man told police. He and the people with him also took the man’s iPhone 4, wedding band and wallet.
