It was worth $1.5 million. Witnesses said that a couple caught their eyes because they seemed too young to be interested in such expensive jewelry. In his store, a salesman said that the couple were dressed in clothing that seemed too casual(随便)for the jewelry show. According to a saleswoman who talked with them, the couple said that they were interested in a special necklace for the woman to wear at their wedding next month. The man said that he was a well-known sportsman, so many reporters and guests would come to the wedding ceremony.

The saleswoman left the couple looking at the necklace when she went to help an elderly man who fell out of his wheelchair. Unfortunately, when she got back, the couple and the necklace were gone. The police have realized that the old man was part of the robbery plan.
