Why would a thief steal a tracking device with a built-in GPS satellite receiver? Obviously he didn't know what he was stealing. Or, that the portable tracking device was a part of the home detention program of the Rock County Jail for off-site prisoners.
By the time the prisoner called to report the theft, the device had already automatically notified the jail that it was on the run. The device and the thief was easily tracked through the Internet. A trail of electronic dots led authorities to an apartment building and the thief.
