Digital Evidence in Florida Criminal Cases
Today’s criminal investigations rarely rely solely on eyewitness testimony. Instead, prosecutors increasingly build cases using digital evidence collected from smartphones, computers, social media accounts, surveillance systems, cloud storage, GPS data, and other electronic devices.
Whether you are accused of DUI, drug crimes, domestic violence, theft, fraud, firearm offenses, or other criminal charges, electronic evidence may become one of the most important—and most contested—parts of your case.
At Landsman Law, we regularly review digital evidence obtained during criminal investigations throughout Gainesville, Alachua County, Marion County, Levy County, Bradford County, Baker County, Gilchrist County, Putnam County, and North Florida.
Authority
- U.S. Const. amend. IV
- Art. I, § 12, Fla. Const.

Almost every criminal case today involves some form of digital evidence.
How Do Police Obtain Digital Evidence?
Law enforcement may obtain electronic evidence in several ways.
Examples include:
Search Warrants
Police frequently obtain search warrants for:
- cell phones,
- computers,
- cloud accounts,
- email,
- social media accounts.
Authority
- Ch. 933, Fla. Stat.
- Riley v. California, 573 U.S. 373 (2014)
Consent
Many people voluntarily hand officers their phones or provide passwords.
Voluntary consent may eliminate the need for a warrant.
Never assume you are required to consent.

Authority
- Schneckloth v. Bustamonte, 412 U.S. 218 (1973)
Subpoenas
Some records may be obtained directly from service providers.
Examples include:
- phone records,
- subscriber information,
- business records.
Different legal standards apply depending upon the type of information requested.
Search Incident to Arrest
Police may seize a phone during an arrest.
However, they generally may not search its digital contents without a warrant unless another recognized exception applies.
A traffic stop can create separate Fourth Amendment issues involving the vehicle and electronic devices. See Florida vehicle search laws.
Authority
- Riley v. California, 573 U.S. 373 (2014)
Cell Phone Evidence
Modern smartphones contain years of personal information.
Investigators frequently examine:
- texts,
- emails,
- photographs,
- videos,
- contacts,
- internet history,
- banking apps,
- social media,
- GPS history,
- deleted files.
Forensic software may recover information users believe has been deleted.
Authority
- Riley v. California, 573 U.S. 373 (2014)
Text Messages
Text messages often become critical evidence.
Police may attempt to prove:
- intent,
- knowledge,
- planning,
- identity,
- admissions,
- witness coordination.
Defense attorneys often examine:
- authenticity,
- missing messages,
- context,
- authorship,
- timestamps.
Social Media Evidence
Investigators frequently review:
- Snapchat
- TikTok
- X (formerly Twitter)
- Signal
- Telegram
Posts intended for friends may later appear before a jury.
Deleting posts after learning of an investigation may create additional legal issues.
GPS and Location Data
Location evidence may come from:
- Google Timeline
- Apple devices
- vehicle navigation
- cell tower records
- location services
- fitness trackers
Location evidence is not always precise.
Defense attorneys often investigate:
- margin of error,
- device ownership,
- account sharing,
- data reliability.
Cloud Storage
Investigators increasingly seek:
- iCloud
- Google Drive
- Dropbox
- Microsoft OneDrive
These accounts may contain years of photographs, documents, and backups.
Surveillance Video
Digital video may include:
- Ring cameras
- business surveillance
- apartment security
- ATM cameras
- traffic cameras
- body cameras
- dash cameras
Video frequently raises issues involving:
- preservation,
- authenticity,
- editing,
- missing footage.
Can Police Recover Deleted Files?
Sometimes.
Deleted information is not always permanently erased.
Digital forensic examinations may recover:
- deleted photographs,
- deleted texts,
- browser history,
- file fragments,
- metadata.
Whether recovery is successful depends on the device and subsequent use.
Metadata
Metadata is “data about data.”
Examples include:
- when a photo was taken,
- GPS coordinates,
- device information,
- file creation dates,
- modification history.
Metadata often becomes important in criminal investigations.
Authentication of Digital Evidence
Before electronic evidence may be admitted at trial, prosecutors generally must establish that it is authentic.
Questions often include:
- Who created it?
- Has it been altered?
- Is it complete?
- Who had access?
- Can it be accurately identified?
Authority
- §§ 90.901–90.902, Fla. Stat.
Chain of Custody
Electronic evidence must often be properly documented from seizure through trial.
Problems with chain of custody may affect the weight or admissibility of evidence.
Authority
- § 90.901, Fla. Stat.
Expert Witnesses
Many digital evidence cases require expert testimony.
Experts may address:
- forensic extraction,
- data preservation,
- software reliability,
- metadata,
- GPS accuracy,
- cell tower analysis.
Can Digital Evidence Be Suppressed?
Yes.
Possible arguments include:
- illegal search,
- invalid warrant,
- unlawful seizure,
- lack of probable cause,
- warrant exceeded scope,
- involuntary consent,
- Fourth Amendment violations.
Authority
- Fla. R. Crim. P. 3.190(g)
- Franks v. Delaware, 438 U.S. 154 (1978)
- See – Franks Hearing in Florida
Common Mistakes People Make
After learning of an investigation, people sometimes:
- delete texts,
- erase photographs,
- factory reset phones,
- delete social media,
- contact witnesses,
- change passwords,
- destroy devices.
These actions may create additional legal problems and make defending the underlying case more difficult.
Instead, preserve evidence and consult an attorney promptly.
