AT&T Is Spying on Americans for Profit, New Documents Reveal

On Nov. 11, 2013, Victorville, California, sheriff’s deputies and a coroner responded to a motorcyclist’s report of human remains outside of town.

They identified the partially bleached skull of a child, and later discovered the remains of the McStay family who had been missing for the past three years. Joseph, 40, his wife Summer, 43, Gianni, 4, and Joseph Jr., 3, had been bludgeoned to death and buried in shallow graves in the desert.

Investigators long suspected Charles Merritt in the family’s disappearance, interviewing him days after they went missing. Merritt was McStay’s business partner and the last person known to see him alive. Merritt had also borrowed $30,000 from McStay to cover a gambling debt, a mutual business partner told police. None of it was enough to make an arrest.

Even after the gravesite was discovered and McStay’s DNA was found inside Merritt’s vehicle, police were far from pinning the quadruple homicide on him.

Until they turned to Project Hemisphere.

Hemisphere is a secretive program run by AT&T that searches trillions of call records and analyzes cellular data to determine where a target is located, with whom he speaks, and potentially why.

“Merritt was in a position to access the cellular telephone tower northeast of the McStay family gravesite on February 6th, 2010, two days after the family disappeared,” an affidavit for his girlfriend’s call records reports Hemisphere finding (PDF). Merritt was arrested almost a year to the date after the McStay family’s remains were discovered, and is awaiting trial for the murders.

In 2013, Hemisphere was revealed by The New York Times and described only within a Powerpoint presentation made by the Drug Enforcement Administration. The Times described it as a “partnership” between AT&T and the U.S. government; the Justice Department said it was an essential, and prudently deployed, counter-narcotics tool.

How Law Enforcement Tracks Cellular Phones


Recent news stories, notably this story in USA Today and this story in the Washington Post, have brought to light extensive use of "Stingray" devices and "tower dumps" by federal -- and local -- law enforcement agencies to track cellular telephones.

Just how how does all this tracking and interception technology work? There are actually a surprising number of different ways law enforcement agencies can track and get information about phones, each of which exposes different information in different ways. And it's all steeped in arcane surveillance jargon that's evolved over decades of changes in the law and the technology. So now seems like a good time to summarize what the various phone tapping methods actually are, how they work, and how they differ from one another.

Note that this post is concerned specifically with phone tracking as done by US domestic law enforcement agencies. Intelligence agencies engaged in bulk surveillance, such as the NSA, have different requirements, constraints, and resources, and generally use different techniques. For example, it was recently revealed that NSA has access to international phone "roaming" databases used by phone companies to route calls. The NSA apparently collects vast amounts of telephone "metadata" to discover hidden communications patterns, relationships, and behaviors across the world. But, as interesting and important as that is, it has little to do with the phone tracking techniques used by local law enforcement, and it's not what we're talking about here.

Phone tracking by law enforcement agencies, in contrast to intelligence agencies, is intended to support investigations of specific crimes and to gather evidence for use in prosecutions. And so their interception technology -- and the underlying law -- is supposed to be focused on obtaining information about the communications of particular targets rather than of the population at large...
