The mysterious craigslist bank robbery caper is now much less mysterious, as a suspect in the case has been arrested by police in Monroe, Washington. Law enforcement had collected DNA and other evidence after the robbery went down last month, and this week, they were able to catch 28-year-old Anthony Curcio while he was trying to pick up his car, which he had left in a Target parking lot.

Bank robberies are a little passé these days, and they don't normally make headlines on the Internet, but this one attracted some major attention because of the creative method Curcio allegedly used to confuse police. He had reportedly used an open WiFi connection (in an attempt to remain as anonymous as possible) to post an ad on the popular classifieds site, craigslist, offering road construction work at $28.50 per hour near Seattle. About a dozen men replied to the ad, and all received instructions to show up outside a Bank of America wearing a yellow vest, safety goggles, a respirator mask, and a blue shirt.

As the properly attired men gathered outside the bank, Curcio allegedly arrived wearing the same getup. He then used pepper spray on a guard transporting cash from an armored truck into the bank. Curcio grabbed the duffel bag, ran to a nearby river, and floated away on an inner tube. When law enforcement arrived, they were baffled to see a group of men standing around, all matching the description of the robber.

As it turns out, Curcio may be quite Internet-savvy, but he's not quite so bank-robbery-savvy. He apparently left some DNA at the scene, which police connected to a report they had received before the robbery about a man who picked up a wig, safety vest, and a large can of mace before driving away. Police were able to connect the license plate on that car—which had not been involved in a crime at that point—to Curcio and confirmed his involvement through the DNA.

Then, they staked out his car in the Target parking lot until Curcio returned to pick it up this week. According to The Register, Curcio has been charged with first-degree robbery, while a second suspect was charged with possession of stolen property. Presumably, all of the innocent craigslist henchmen have already moved on with their lives.

Law enforcement is often quite nervous about open wireless networks because criminals could use them for nefarious purposes without ever getting caught. However, as exemplified by this case, anonymous WiFi will only get someone so far. Criminals are likely to get caught anyway, thanks to things they do off the airwaves.
