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.

However, AT&T's own documentation—reported here by The Daily Beast for the first time—shows Hemisphere was used far beyond the war on drugs to include everything from investigations of homicide to Medicaid fraud.

Hemisphere isn't a "partnership" but rather a product AT&T developed, marketed, and sold at a cost of millions of dollars per year to taxpayers. No warrant is required to make use of the company's massive trove of data, according to AT&T documents, only a promise from law enforcement to not disclose Hemisphere if an investigation using it becomes public.

So, AT&T's one stipulation is a pinky swear with law enforcement that their program won't cause them public embarrassment.

    If it's essential, then how did they ever catch anyone before they had that "essential" tool?
