It’s not a ruling, as there is no majority of the Pennsylvania Supreme Court in its Commonwealth v. Kurtz opinion saying so, but that’s only because the fourth vote held it unnecessary to reach the question. The point, nonetheless, is clear. While the Supreme Court’s decision in Carpenter v. United States may have carved out a narrow exception to the Third Party Doctrine for cellphones, as a theoretical body part to which people have no real option to possess at all times and thus compelled to provide information to third-party providers, Google search is a voluntary act for which no warrant is needed.
In the case, the police were trying to find out who committed a sexual assault of a person known in the opinion by her initials, “K.M.” Police figured that whoever committed this crime may have googled K.M.’s name or address before committing the crime. Investigators obtained what is known as a “reverse keyword search warrant,” asking for Google to hand over the I.P. address of whoever may have googled the name or address of the victim shortly before the crime. Google responded that someone at a particular I.P. address had conducted two searches for K.M.’s address a few hours before the attack. The I.P. address was in use at the home of the defendant, Kurtz. The police had not suspected Kurtz in the crime, but they started to watch Kurtz closely, obtained a DNA sample, and found a DNA match from the crime.
