Commonwealth v. Kurtz: Can Your Google Searches Be Used in a Pennsylvania Criminal Case?

The Pennsylvania Supreme Court recently addressed an important question in criminal investigations:

Does a person have a constitutional expectation of privacy in the records created by ordinary Google searches?

In Commonwealth v. Kurtz, the Court answered that question in a way that gives law enforcement significant room to use search-engine records in criminal investigations.

The case involved a reverse keyword search warrant, Google records, IP address information, DNA evidence, and a challenge under the Fourth Amendment and Article I, Section 8 of the Pennsylvania Constitution.

The Court ultimately affirmed the judgment below and held that the average person does not have a reasonable expectation of privacy in records generated by general, unprotected internet searches.

That ruling matters because internet searches are often deeply personal. People search for addresses, health concerns, legal issues, personal relationships, financial problems, locations, and private questions. But under this decision, ordinary search-engine activity may not receive the same constitutional privacy protection as other kinds of digital information.

What Happened in the Case?

The case involved a serious criminal investigation in Northumberland County.

According to the opinion, the Pennsylvania State Police were investigating a violent assault and abduction. The victim could not identify the attacker, and DNA testing at first did not reveal a known match.

Investigators believed the crime may not have been random. The victim’s home was remote. The circumstances suggested the attacker may have known the victim, her residence, or her husband’s work schedule. Investigators also believed the perpetrator may have researched the victim’s name or address before the crime.

Police had no direct evidence that the perpetrator used Google to plan the offense. But they believed it was possible.

So investigators applied for and obtained what the Court described as a reverse keyword search warrant.

What Is a Reverse Keyword Search Warrant?

A normal search warrant is usually aimed at a specific person, place, phone, account, home, car, or device.

A reverse keyword search warrant works differently.

Instead of saying:

“We believe John Doe searched for this information.”

The government asks something closer to:

“Tell us who searched for these particular words or terms during this time period.”

In Kurtz, the warrant was not directed at a known suspect. Instead, it sought Google’s records for anyone who searched for the victim’s name or address during the relevant time period.

Google later reported that someone had searched for the victim’s address a few hours before the attack. Investigators determined that the same IP address was used for the searches and that the IP address was associated with Kurtz’s residence.

That information helped lead police to Kurtz. Investigators then obtained DNA from a discarded cigarette butt, compared it to DNA recovered from the victim, and obtained a match. Kurtz was later arrested and confessed to the charged conduct and other assaults.

The Suppression Issue

Kurtz moved to suppress the evidence obtained from Google’s records.

His argument was essentially that the government lacked constitutionally adequate probable cause to obtain the Google search data. He challenged the idea that police could obtain search records when the suspect was unknown and there was no direct evidence that Google had actually been used in planning or committing the crime.

But before a court reaches probable cause, a defendant usually must first show that he had a reasonable expectation of privacy in the place, item, record, or information searched.

That became the key issue.

The Pennsylvania Supreme Court had to decide whether a person has a reasonable expectation of privacy in records generated by general, unprotected internet searches.

The Court’s Holding

The Court held that the average search-engine user does not have a reasonable expectation of privacy in records generated by ordinary, unprotected internet searches.

Because the Court found no reasonable expectation of privacy, it did not reach the probable-cause issue.

That is a major point.

The Court did not say that the warrant definitely had probable cause.

Instead, the Court said that Kurtz could not challenge the warrant because he had no protected privacy interest in the records at issue.

In plain English:

If there is no reasonable expectation of privacy, then there is no constitutional “search” for Fourth Amendment purposes.

And if there is no constitutional search, the Commonwealth does not have to prove probable cause for the defendant to lose the suppression issue.

Why the Court Found No Privacy Interest

The Court focused on the nature of general Google searches.

When a person types a search into Google and presses enter, the user is transmitting that search to Google. Google receives the query, processes it, and generates records connected to that search.

The Court treated that activity as information voluntarily conveyed to a third party.

That matters because of the third-party doctrine.

Under the third-party doctrine, a person often loses constitutional privacy protection in information voluntarily shared with someone else. The classic idea is that if you voluntarily give information to a third party, you assume the risk that the third party may later disclose it to the government.

The Court applied that reasoning to general, unprotected Google searches.

The opinion also emphasized that its analysis was limited. The Court specifically stated that it was dealing with general, unprotected internet searches — basically opening a search engine, typing words into the search bar, and hitting enter.

The Court did not decide whether a different result might apply when a user takes additional privacy-protective steps.

That limitation is important.

What the Court Did Not Decide

This case does not answer every digital privacy question.

The Court did not decide whether there would be a privacy interest in more secure or protected internet searches.

It did not decide the constitutional effect of encrypted search tools, privacy-focused browsers, VPNs, anonymizing tools, private accounts, password-protected data, or other privacy measures.

It also did not decide whether the Google warrant itself was supported by probable cause.

That issue was granted for review, but the Court did not reach it because it found that Kurtz lacked a reasonable expectation of privacy in the Google search records.

For criminal defense purposes, that matters. The probable-cause issue remains one of the most troubling parts of reverse keyword search warrants. These warrants can begin with no identified suspect and ask a technology company to search through user activity to find people who searched certain words.

That is a powerful investigative tool.

Why This Case Matters

This case is important because it sits at the intersection of criminal law, digital privacy, and modern police investigations.

People now use search engines for almost everything.

They search addresses.
They search symptoms.
They search legal questions.
They search court dates.
They search names.
They search directions.
They search businesses.
They search private personal information.

The Court recognized that the internet is now an integral part of everyday life. But it still held that ordinary search-engine records are not automatically protected by a reasonable expectation of privacy.

That creates a serious practical reality:

What someone searches online may become evidence in a criminal case.

How This Can Affect Criminal Investigations

Google searches can be powerful evidence.

In some cases, prosecutors may use search history to argue planning, motive, knowledge, intent, location, identity, or consciousness of guilt.

Examples could include searches for:

A victim’s address;
How to commit or hide a crime;
How long drugs stay in the body;
How to avoid police detection;
Directions to or from a location;
Information about weapons;
Information about criminal penalties;
Information about a person, business, or residence;
Information about deleting evidence.

But search history can also be misleading.

A person may search something out of curiosity.
A person may search something after hearing about it from someone else.
A device may be shared.
A Wi-Fi network may be used by multiple people.
An IP address may identify a location, not necessarily the person using the device.
The search may lack context.
The search terms may be ambiguous.

That is why digital evidence should always be carefully examined.

The Defense Still Has Arguments

Even after Kurtz, the defense is not powerless in cases involving Google searches or other digital records.

The defense may still challenge:

Whether the records actually connect to the accused person;
Whether the device was shared;
Whether other people had access to the account, Wi-Fi, or IP address;
Whether the search terms are being taken out of context;
Whether the warrant was overbroad;
Whether other constitutional protections apply;
Whether the search involved protected accounts, devices, or private communications;
Whether the Commonwealth can authenticate the records;
Whether the records are complete and reliable;
Whether police exceeded the scope of the warrant;
Whether later evidence was tainted by illegal police conduct;
Whether the Commonwealth can prove identity beyond a reasonable doubt.

In other words, even if a defendant cannot suppress ordinary Google search records based on a privacy-expectation argument, the defense may still be able to challenge how the Commonwealth interprets and uses those records.

Reverse Keyword Warrants Raise Serious Concerns

A reverse keyword warrant is different from a typical warrant because it can start with no suspect.

The government identifies search terms and asks the company to identify users who searched those terms.

That kind of warrant can be useful in serious cases, but it also raises obvious privacy concerns.

Many people could search the same word or phrase for innocent reasons.

A person may search an address because they are delivering food, visiting a friend, researching property, checking directions, reading news, or looking up a business. Search terms alone do not always tell the full story.

The risk is that innocent people can be swept into an investigation because their search activity matches a keyword selected by police.

That is why these warrants should be scrutinized carefully.

What This Means for Pennsylvania Criminal Defense

For criminal defense lawyers in Pennsylvania, Kurtz is an important case to know.

It means that when the Commonwealth obtains ordinary Google search records, the defense may face an uphill battle arguing that the defendant had a reasonable expectation of privacy in those search records.

But the case also leaves room for future litigation.

The Court limited its analysis to general, unprotected internet searches. That leaves open questions involving more secure methods of searching, private platforms, protected accounts, encrypted tools, and other forms of digital data.

It also leaves open case-specific arguments about overbreadth, reliability, authentication, identity, interpretation, and the scope of the warrant.

Digital evidence is not self-explanatory. It needs context.

The Key Takeaway

The key takeaway from Commonwealth v. Kurtz is this:

In Pennsylvania, ordinary Google searches may not be constitutionally private in the way many people assume.

That does not mean every digital search warrant is valid.

It does not mean every search history record proves guilt.

It does not mean the Commonwealth automatically wins every case involving Google records.

But it does mean that courts may allow prosecutors to use ordinary search-engine records in criminal cases without first recognizing a protected privacy interest in those records.

For defendants, that makes early legal review critical.
