A man who arranged to swap a gaming system through Craigs List, and then delivered a box of rocks instead of the system, was arrested Aug. 21 and charged with larceny. Police said Daryl Johnson, 19, of New Haven, was arrested on a warrant for the scam, charged with larceny in the sixth degree. Police said the incident took place July 2 at the Milford Public Library. The victim made arrangements through Craig's List with Johnson to exchange their video game systems with each other at Milford's public library. After the exchange, the victim checked the gaming system he was given and found that the box contained rocks in lieu of the item. Police seized the gaming system from Johnson during a separate unrelated investigation that same day, according to a police press release. Johnson was released from police custody on a promise to appear in court Sept. 16.
