Prosecutors need more than the discovery of a GPS tracker, AirTag, or tracking application to obtain a conviction under Florida Statute § 934.425. They must connect the accused to knowing, nonconsensual installation, placement, or use.

Finding an electronic tracker can immediately create suspicion, but suspicion is not the same as proof beyond a reasonable doubt. Florida Statute § 934.425 criminalizes certain nonconsensual installation, placement, and use of tracking devices and tracking applications, and an ordinary violation is now a felony. The State still must establish the elements of the particular offense it charges. A GPS unit underneath a car, an AirTag hidden inside property, or a location application on a phone may establish that tracking technology existed, but those facts do not necessarily establish who put it there, who used it, whether the property owner consented, or whether a statutory exception applies. As a Florida criminal defense attorney, I would examine every link in that evidentiary chain and challenge any attempt to substitute assumptions for admissible proof.

What Must Prosecutors Prove According To A Florida Criminal Defense Attorney?

Florida Statute § 934.425 generally prohibits a person from knowingly installing or placing a tracking device or tracking application on another person's property without consent. It separately prohibits knowingly using a tracking device or application to determine another person's location or movement, or the location or movement of that person's property, without consent.

The word knowingly matters. The statute does not merely ask whether a tracker existed. Prosecutors need evidence connecting a defendant to the prohibited conduct with the required knowledge.

Depending upon how the information or charging document is framed, I would expect the prosecution to try to establish several points:

  • The technology qualified as a tracking device or tracking application under § 934.425.

  • You knowingly installed, placed, or used the technology.

  • The property or person being tracked fell within the prohibition charged by prosecutors.

  • The person whose consent was required did not consent during the relevant period.

  • No statutory exception defeated the charge.

These issues frequently depend on digital evidence, testimony, ownership records, and a precise timeline. A private attorney can attack one or several of those elements rather than treating the device itself as the entire case.

Does Finding A Tracking Device Prove Who Installed It?

No. Discovering a tracker establishes its existence and location at the time it was found, but it does not automatically identify the person who placed it there.

Police may attempt to establish identity through serial numbers, purchase histories, account registration, billing records, surveillance footage, fingerprints, witness statements, phone records, or admissions. In an AirTag case, for example, investigators may seek records intended to connect the device to an account. In a conventional GPS case, they may identify a subscription or cellular service associated with the unit.

Each link needs to be tested. A purchaser may have given the device to another person. Several employees may share a fleet-tracking account. Family members may use the same credentials. A tracker may have been installed months or years before the complaining witness discovered it.

I would determine whether the State can prove placement, not merely ownership. If the prosecution jumps from "you bought this device" to "therefore you secretly attached it to this car," there may be a significant evidentiary gap.

What Evidence Can Show Someone Used The Tracker?

Florida law also prohibits certain knowing use of tracking technology. That means prosecutors do not necessarily need to prove the defendant physically attached the device if they can prove prohibited use under the statute.

The State may look for evidence such as:

  • Login histories;

  • Application-access records;

  • Device identifiers;

  • Location-history requests;

  • Screenshots of tracking maps;

  • Text messages referring to a person's location;

  • Account subscription records;

  • Emails or notifications associated with the tracker; and

  • Statements acknowledging that location information was viewed.

Those records can look persuasive, but they still require interpretation. An account login does not always establish that the user viewed a particular person's location. Automatic notifications may occur without someone deliberately requesting them, and an account can remain signed into several phones or computers.

A private attorney can seek the underlying data rather than rely solely on a detective's summary of what the technology supposedly shows.

How Does The State Prove Lack Of Consent?

Lack of consent can become one of the most contested issues in a tracking-device prosecution. Couples, families, businesses, and parents routinely share location information for perfectly lawful reasons.

Prosecutors may rely on the complaining witness's testimony that permission was never given or had previously been withdrawn. The defense may have messages, contracts, application invitations, account settings, workplace policies, or witnesses showing otherwise.

The timing of consent can be critical. Permission given one year earlier does not necessarily resolve whether it remained effective during the dates charged.

Florida also creates specific circumstances in which consent is presumed revoked. Section 934.425 provides that previously given consent is presumed revoked when legally married parties experience the filing of a petition for dissolution of marriage. The statute also creates presumed revocation after specified injunction filings under §§ 741.30, 741.315, 784.046, and 784.0485.

I would therefore construct a timeline comparing consent, installation, access, separation, divorce filings, injunction filings, and the period prosecutors identify in the charging document.

What Role Do Vehicle Ownership Records Play?

Ownership evidence can be crucial because § 934.425 contains an exception for qualifying owners and lessees of motor vehicles. The precise statutory conditions must be satisfied, but the title or lease can completely change the legal analysis.

Police may initially describe the vehicle simply as "the victim's car" because that person regularly drives it. Legal ownership may tell a different story.

I would obtain title records, registration, lease documents, purchase contracts, financing records, divorce-property agreements, and transfer documents. Those records can establish who owned or leased the vehicle when the device was installed and when it was allegedly used.

A private attorney should not allow informal descriptions of vehicle ownership to replace documentary evidence when a statutory exception may depend upon that distinction.

What Other Evidence May Police Collect?

Tracking investigations frequently expand beyond the tracker itself. Investigators may search for circumstantial evidence intended to show motive, knowledge, or a pattern of behavior.

That evidence may include surveillance footage showing someone near the vehicle, receipts for the tracker, search history concerning tracking devices, text messages discussing the complaining witness, relationship history, prior arguments, social-media communications, photographs, or evidence that the accused appeared at locations visited by the complaining witness.

Circumstantial evidence can be legally sufficient in appropriate cases, but each inference should be tested. Buying an AirTag does not necessarily prove secret tracking, and being at the same restaurant does not necessarily prove GPS monitoring.

I would compare the timestamps. Sometimes the timeline itself exposes a weakness, such as an alleged suspicious appearance occurring before the tracker was activated.

What If Police Search My Phone?

Phones can become one of the most important sources of evidence in a tracking prosecution. Investigators may look for tracking applications, account credentials, maps, location logs, communications, purchase receipts, photographs, and browser history.

The Fourth Amendment and applicable Florida constitutional protections can create important defense issues. Police generally need lawful authority for the search, which may involve a warrant or a recognized exception.

I would review the warrant, its factual basis, its scope, and what investigators actually searched. If officers exceeded the lawful authority they possessed or obtained evidence through an unconstitutional search, I may seek suppression of the resulting evidence.

The difference can be substantial. If the prosecution's strongest evidence of account use comes from a phone search and that evidence is suppressed, the State's ability to prove identity or knowing use may change considerably.

What Are The Penalties If The State Proves The Charge?

A standard violation of § 934.425 is a third-degree felony under current Florida law. Florida's general penalty provisions allow up to five years of imprisonment for a third-degree felony, and the general maximum fine is $5,000.

If the State proves that the violation was committed to commit or facilitate a qualifying dangerous crime, § 934.425 elevates the offense to a second-degree felony. A second-degree felony generally carries up to 15 years of imprisonment and a fine of up to $10,000.

These maximum penalties do not mean every conviction results in the maximum sentence. Criminal history, the Florida Criminal Punishment Code, accompanying offenses, mitigation, negotiations, and other factors may influence sentencing.

The felony classification nevertheless makes early defense work important. My first objective would be determining whether the charge can be prevented, dismissed, or defeated. When that is not possible, weaknesses in the evidence may still support a reduced charge or reduced penalties.

Defenses A Florida Criminal Defense Attorney May Build From The Evidence

A strong defense often comes from showing what the State's evidence does not establish.

Potential defense issues include lack of proof that you installed the device, inability to establish who accessed an account, evidence of consent, qualifying vehicle ownership, application of another statutory exception, failure to establish knowing conduct, or weaknesses in the technological evidence.

I may also challenge the chain of custody for the tracker, the reliability of account information, witness credibility, the government's interpretation of timestamps, or the legality of searches used to obtain digital information.

The defense does not necessarily need one dramatic piece of evidence. Several smaller weaknesses can create reasonable doubt when the prosecution cannot connect the device, defendant, lack of consent, and alleged use into one reliable chain.

Example of How I May Build the Defense

Consider an illustrative case in which police find a GPS tracker beneath a woman's vehicle. They discover that the subscription was purchased using a credit card belonging to her former boyfriend, and he is arrested under § 934.425.

I would obtain more than the subscription record. Suppose the records reveal that the tracker was purchased as part of a two-device package for a business the former couple jointly operated. Multiple employees had the account password, and surveillance video from the parking area does not show my client near the vehicle during the period when the tracker was believed to have been attached.

The login records then reveal activity from a device not associated with my client. Messages between the former couple also establish that vehicle tracking had previously been used for company purposes.

Those facts could undermine identity, knowing placement, account use, and lack of consent. Depending upon the complete evidence, I could seek dismissal, challenge probable cause, dispute the State's digital attribution, or use the evidentiary weaknesses to pursue a reduced charge or reduced penalties.

This example illustrates defense analysis. It is not presented as a claim concerning an undocumented Musca Law result, and every case depends on its own facts and admissible evidence.

Florida Criminal Defense FAQs About Evidence In Tracking Device Cases

Is Finding A GPS Tracker Enough To Convict Someone?

No. A tracker can establish that technology existed, but the prosecution still needs evidence connecting the defendant to the prohibited conduct. Section 934.425 requires knowing installation, placement, or use under circumstances prohibited by the statute.

Identity, lack of consent, timing, property ownership, and statutory exceptions may all remain disputed. I would investigate each of those issues before assuming the physical device proves the case.

Can Purchase Records Be Used Against Me?

Yes. A receipt, credit-card statement, account subscription, or online purchase history can be circumstantial evidence connecting someone to a device.

Purchase evidence still does not necessarily prove who installed the tracker or who later used it. I would examine whether other people had possession of the device and whether technical records independently connect you to the alleged tracking activity.

Can Text Messages Prove Illegal Tracking?

They can become important evidence. A message admitting that you know where someone is, discussing placement of a tracker, or referring to location information may be offered by prosecutors to establish knowledge or use.

Context matters. I would review the complete conversation rather than an isolated screenshot because surrounding messages may substantially change the meaning of a statement.

Does The State Have To Prove I Actually Looked At The Location?

It depends on the theory charged. If prosecutors rely on unlawful use, evidence that you knowingly accessed tracking information can become central. If they rely on unlawful installation or placement, they may attempt to prove the offense without establishing repeated location checks.

A defense attorney should determine precisely which statutory theory the State is pursuing and require prosecutors to prove that theory rather than shifting between theories whenever one becomes difficult to establish.

Can The Complaining Witness's Testimony Be Enough To Show No Consent?

Witness testimony is evidence and can be significant, but it can also be challenged. The defense may possess messages, account invitations, contracts, vehicle records, or witnesses that contradict a later claim that tracking was never authorized.

I would compare statements made to police with earlier communications and objective records. In relationship disputes especially, contemporaneous records may provide important context that was missing from the initial report.

Why Do I Need A Private Attorney If Police Already Found The Device?

Because finding the device may be the beginning of the legal analysis rather than the end. The State still has to prove identity, knowledge, lack of consent, the statutory nature of the technology, and the absence of a defense or exception.

A private attorney can preserve favorable records, examine the government's digital evidence, challenge unconstitutional searches, question the chain of custody, locate consent evidence, and pursue dismissal or reduction before assumptions become entrenched in the prosecution.

The State may have an AirTag, GPS unit, phone application, or account record, but a criminal conviction requires proof of the elements of § 934.425 beyond a reasonable doubt. I would examine whether the evidence actually connects you to knowing, nonconsensual tracking and whether constitutional or statutory defenses can prevent the State from using important evidence.
