–Judge Denies Motion to Suppress Evidence Gathered With Cell Tower
Spoofing Technology
(May 8, 2013)
A judge in Arizona will allow evidence collected by federal
investigators through the use of technology known as stingray, which
mimics a cell phone tower. The defense had filed a motion to suppress
the evidence, claiming that the use of stingray violated Daniel
Rigmaiden's Fourth Amendment rights because there was no warrant for the
search of his apartment. The judge determined that Rigmaiden did not
have a reasonable expectation of privacy because he had obtained all of
those things fraudulently - using others' identities. (((What a weird and
ingenious argument.)))
Rigmaiden allegedly filed hundreds of phony tax returns using the names of people
who had died. He is the alleged mastermind in a scheme that stole US $4
million from the IRS through fraudulent tax returns. The judge also said
that the government did not act improperly by failing to inform the
magistrate judge who authorized the tracking activities that it planned
to use a stingray to track the suspect or explain how the technology
worked.
