Criminal Procedure - Forensic Genetic Genealogical DNA Analysis and Search - Affidavit for Judicial Authorization
Summary
HB301 makes a targeted change to Maryland’s rules for forensic genetic genealogical DNA analysis and search (FGGS), a law-enforcement tool used to help identify unknown suspects or victims through genetic genealogy. The bill clarifies what must be included in the sworn affidavit that law enforcement submits to obtain judicial authorization before starting an FGGS investigation.
Under the bill, the affidavit must state that the perpetrator’s identity is unknown, that the case involves murder, rape, a felony sexual offense, or another serious crime posing a substantial and ongoing threat to public safety or national security, that the biological sample is reasonably believed to come from the perpetrator or related crime scene evidence, and that an STR DNA profile has already been developed and failed to identify a known person in state and national DNA databases. The bill also removes language that could be read to require all investigative leads to be exhausted before FGGS may begin, while making clear that the law does not require every lead to be pursued before authorization.
Impact
HB301 amends Criminal Procedure Article §17-102, refining the affidavit requirements for court-approved FGGS investigations in Maryland. It does not expand the underlying authority to use FGGS, but it changes the procedural showing law enforcement must make and clarifies that investigators are not barred from seeking FGGS simply because not every possible lead has been exhausted. The bill takes effect October 1, 2025, and affects law enforcement agencies, prosecutors, courts, and cases involving serious violent crimes or public-safety/national-security threats.
Sentiment
The bill appears to have been broadly supported and noncontroversial in the legislature. It passed the House and Senate with unanimous recorded votes, indicating strong bipartisan agreement or at least no recorded opposition. The available record shows no committee transcript debate, which suggests the measure was treated as a technical or clarifying update rather than a major policy dispute.
Contention
The main point of potential contention is the balance between investigative flexibility and procedural safeguards. Supporters of the change would likely view the bill as clarifying an existing process and preventing unnecessary delay in serious cases, while any critics might worry that removing the explicit requirement to exhaust investigative leads could lower the threshold for using a powerful genetic investigation tool. The bill addresses that concern in part by retaining judicial authorization and limiting FGGS to serious crimes and unknown perpetrators.
