IRS Used Cellphone Location Data To Try To Find Suspects (wsj.com) 24
Justin Cole, a spokesman for IRS CI, said it entered into a "limited contract with Venntel to test their services against the law enforcement requirements of our agency." IRS CI pursues the most serious and flagrant violations of tax law, and it said it used the Venntel database in "significant money-laundering, cyber, drug and organized-crime cases." "The tool provided information as to where a phone with an anonymized identifier (created by Venntel) is located at different times," Mr. Cole said. "For example, if we know that a suspicious ATM deposit was made at a specific time and at a specific location, and we have one or more other data points for the same scheme, we can cross reference the data from each event to see if one or more devices were present at multiple transactions. This would then allow us to identify the device used by a potential suspect and attempt to follow that particular movement."
IRS CI "attempted to use Venntel data to look for location records for mobile devices that were consistently present during multiple financial transactions related to an alleged crime," Mr. Cole said. He said that the tool could be used to track an individual criminal suspect once one was identified but said that it didn't do so because the tool produced no leads.
