An anonymous reader writes "A Facebook photo of a stolen 3 carat diamond ring recently helped police solve a jewelry theft. After rings and other items valued at more than $16,000 were taken from a home on Saturday, a friend of the victim's roommate saw one of the items on the social network. 20-year-old Crystal Yamnitzky captioned the photo with the following message: 'Look what Robby gave me I love him so much,' in reference to her 21-year-old boyfriend Robert Driscoll. Yamnitzky's cousin saw the post and told some friends, who alerted police. Both Yamnitzky and Driscoll have been charged in the case."
