One of the victims was a 60-year old man who was murdered at Victory Park Monday night. Police say he was targeted for his gold-chain.
More than 170 similar robberies have been reported in Stockton this year, and some of the victims have been children.
Most of the crimes involve the suspects running up to the victims and yanking off their gold necklaces. But there have been instances of women having their gold-earrings torn off.
