Challenging Digital Evidence in Maryland Criminal Cases: Cell Phone Data, Social Media Records, and Constitutional Search Issues
Digital evidence is not admissible merely because police recovered it from a phone or social media account. A criminal attorney in Baltimore can attack the search, the warrant, its execution, and the State’s ability to connect the evidence to the accused.
Maryland Rule 4-252 requires certain suppression issues to be raised before trial. The Law Offices of Terri D. Mason can review the warrant, affidavit, extraction report, and provider records for grounds to suppress or exclude digital evidence. The strongest challenges often focus on the lack of probable cause, an overbroad warrant, false or misleading affidavit statements, improper authentication, and separate hearsay or provider-record objections.
Challenge the Probable Cause Nexus to the Device
A warrant must establish probable cause to believe evidence of the identified crime will be found on the device. The Fourth Amendment does not permit police to assume every phone contains evidence simply because a suspect owns one. In Moats v. State, Maryland courts examined the factual connection between a seized phone and criminal investigations. A criminal lawyer should challenge affidavits that fail to explain why texts, photographs, applications, location records, or files are likely to contain evidence.
Attack Warrants That Lack Particularity
Probable cause does not authorize a general forensic search. Riley v. California recognizes privacy interests in modern cell phones. Maryland’s Richardson v. State held that a warrant permitting officers to search everything on a phone violated the Fourth Amendment’s particularity requirement. Criminal lawyers in Maryland will compare authorized data categories, dates, accounts, and offenses against the extraction. Evidence found beyond those limits may support suppression.
Challenge False or Misleading Warrant Affidavits
Franks v. Delaware permits a defendant, after the required preliminary showing, to challenge material warrant statements made knowingly, intentionally, or with reckless disregard for truth. A criminal attorney can compare the affidavit with body-camera footage, police reports, witness statements, timestamps, and forensic records. If probable cause fails after false information is removed, the defense can seek suppression.
Force the State to Authenticate Social Media Evidence
Maryland Rule 5-901 requires authentication. In Griffin v. State, Maryland’s highest court rejected inadequate authentication of MySpace evidence because identifying details did not establish who created the post. Sublet v. State requires proof from which a reasonable juror could find social-media evidence authentic. Shared passwords, multiple users, altered screenshots, missing metadata, and incomplete message chains support exclusion.
Raise Hearsay and Provider-Record Objections
Authentication does not make every digital statement admissible. Maryland Rule 5-802 generally bars hearsay unless an exception applies, so a criminal attorney can challenge individual texts or social media statements the State offers for their truth. Provider records raise a separate issue. Carpenter v. United States requires a warrant for historical cell-site location data in many circumstances, allowing the defense to challenge location evidence obtained without constitutionally sufficient process.
