Can Police Keep Your Cell Phone Forever?
By Tripp Stroud | Valley View Law
In high-stakes felony defense, what you don’t do is often just as dangerous as what you do. A recent decision from the Wisconsin Court of Appeals, State v. Zimmerman (2025), provides a chilling example of how a cell phone you thought was "dealt with" years ago can come back to dismantle your life. It’s crucial to hire an experienced and aggressive attorney to avoid the mistakes that happened in the Zimmerman case.
The Background: The Case of the Forgotten Phone
In 2015, Ryan Zimmerman was investigated for a crime. He consented to the police seizing and searching his cellphone. They found nothing of evidentiary value at the time. Zimmerman was convicted of other charges, served his time, and was released in 2017.
The mistake? The police kept his phone in an evidence room. Zimmerman never asked for it back, and he never revoked his consent.
The 2019 "Discovery"
Fast forward to 2019. Zimmerman was under investigation for new, serious allegations involving sexual exploitation and child pornography. A detective realized the old phone was still in the evidence locker. Using new technology that didn't exist in 2015, the police searched the phone again and found images that led to new felony charges.
Zimmerman’s defense team argued that keeping a phone for three years without a warrant or a pending case was an "unreasonable seizure" under the Fourth Amendment.
The Court’s Ruling: The Silence Loophole
The Court of Appeals upheld the search. Their logic was simple and devastating: Because Zimmerman never asked for his phone back and never revoked his original 2015 consent, the police’s continued possession of it was "reasonable."
The Court noted that Zimmerman had statutory means to get his property back (under WIS. STAT. § 968.20) but chose not to use them. His silence was interpreted as ongoing permission.
The Lesson: Why "Wait and See" is a Fatal Strategy
State v. Zimmerman is a masterclass in why a "generalist" defense isn't enough when the stakes are life-altering. At Valley View Law, we see the "Chaos" in this ruling—the trap that catches people who assume the system will be fair.
To protect our clients, we apply an Intensive, Low-Volume Strategy that addresses these hidden risks:
Don’t give consent to search in the first place: You have a constitutional right against unreasonable searches and seizures. Under no circumstances should you voluntarily consent to a search of your property without first consulting an experienced criminal defense lawyer. Respectfully request that the cops get a warrant.
Immediate Property Reclamation: We don't let the State sit on your property. If the police seize a device, It is critical to consider suppressing that seizure or forcing the return of the property the moment its evidentiary value is exhausted.
Explicit Revocation of Consent: At the beginning of a case, we ensure that any consent given—even if given before we were retained—is formally and legally revoked in writing under Wis. Stat. 968.20. We close the loopholes that allow the State to go "fishing" years later.
Move from Chaos to Clarity
The Zimmerman case proves that the State has a long memory and a long arm. If the police have ever seized your property, or if you are currently under investigation for a serious felony, your privacy is at risk every second you remain silent.
Don't let your past become the prosecution's future.
