Roseville Police Department investigators have arrested a Roseville man on suspicion of using Craigslist, the Internet classified advertising web site, to defraud a couple in Seattle. Detectives are looking into similar fraud cases involving victims in four states. Anthony Vincenzo Iacolino, 27, of Roseville is suspected of placing an ad on Craigslist in Seattle in October, offering a laptop computer for sale. When the Seattle couple contacted Iacolino about buying the laptop, they were told that the laptop would be shipped as soon as they paid for it. The victims paid the suspect, using an electronic fund transfer. The victims were e-mailed a phony tracking number for their shipment, but never received the laptop. The Seattle couple reported the fraud to the Roseville Police Department. Roseville Police detectives arrested Iacolino at his Roseville home on Jan. 13 on suspicion of grand theft. He was booked into the Roseville Police Department Jail and released on a $5,000 bail bond. Investigators believe there are additional fraud victims in Washington, Texas, Color-ado and Southern California.The investigation is continuing.
