Iowa
Iowa has no forensic science commission, no lab accreditation mandate and no analyst license. Criminalistics lab staff are presumed qualified, and their reports come in without live testimony unless a party asks at least ten days before trial. Rule 5.702 has no reliability prongs and has not taken up the 2023 federal change. In 2024 Iowa repealed the medical examiner’s interagency coordinating council. Since July 1, 2026, police must keep sexual assault kits for at least 20 years, or for a minor victim’s lifetime.

At a glance
- Oversight body
- None for crime labs. No forensic science commission or lab oversight board was found. The criminalistics laboratory is under the “control, direction, and supervision of the commissioner of public safety” (Iowa Code 691.1), who makes rules on lab capabilities and evidence handling (691.3). The medical examiner’s interagency coordinating council (former 691.6B), which advised the state medical examiner, was repealed effective July 1, 2024 (2024 Iowa Acts ch. 1170, § 368).
- Lab accreditation
- No mandate found. Iowa Code chapters 13, 80, 81, 124, 232, 321J, 690, 691, 692, 709, 810, 822 and 915 contain no accreditation requirement for the crime lab, and neither do the lab rules (IAC 661-150, readopted effective February 25, 2026) or the DNA database rules (IAC 661-156, readopted effective August 12, 2026). Post-conviction DNA testing must follow “guidelines generally accepted by the scientific community” when the profile is not eligible for the national index (Iowa Code 81.11(2)), and database comparisons must meet the NDIS operational procedures manual (81.12). These are standards, not an accreditation mandate.
- Analyst licensing
- None. Any criminalistics lab employee or technician “is presumed” qualified, and lab reports are received in evidence as if the analyst testified, unless a party requests live testimony at least ten days before trial (Iowa Code 691.2). The state medical examiner must be a licensed physician who is board-certified or board-eligible in anatomic and forensic pathology (691.5).
- Admissibility standard
- Iowa R. Evid. 5.702: a qualified expert may testify if specialized knowledge “will help the trier of fact” (Rules of Evidence, ch. 5). The rule has no reliability prongs. It was last amended effective January 1, 2017, and Iowa has not adopted the 2023 change to Federal Rule 702. In Ranes v. Adams Laboratories, Inc., 778 N.W.2d 677 (Iowa 2010), the Iowa Supreme Court kept its “liberal view” of expert admissibility: the “ad hoc Hall test remains our general approach to evaluating reliability.” Courts are encouraged to use Daubert considerations in complex scientific cases, but Daubert is “not appropriate” for technical or other specialized knowledge.
- Post-conviction forensic relief
- No changed-science statute. DNA only. A person convicted of a felony or aggravated misdemeanor may apply for DNA profiling (Iowa Code 81.10). The court “shall grant” it if, among other conditions, the sample was never profiled or the applicant seeks “a new method or technology that is substantially more probative” (81.11(1)(a)), and the results “would raise a reasonable probability that the defendant would not have been convicted” (81.11(1)(e)). Favorable results are a ground for postconviction relief (822.2(1)(h)) and a “ground of fact” that escapes the three-year limit (822.3). Newly discovered evidence is a general ground (822.2(1)(d)).
- DNA database scope
- Convictions only; no arrestee collection. Samples are required from people with a felony deferred judgment or a felony or aggravated-misdemeanor conviction, juveniles adjudicated for qualifying offenses, people found not guilty by reason of insanity of qualifying offenses, sexually violent predators and registered sex offenders (Iowa Code 81.2). Expungement is by written request only, when the qualifying conviction was reversed on appeal and the case dismissed, or for voluntary relative samples, unless the person is otherwise obligated (81.9). A 2026 bill to add felony and aggravated-misdemeanor arrestees, HF 2624, did not pass.
- Facial recognition
- No statute found in Iowa Code chapters 80, 690 or 692. Iowa Code 690.4(2) only requires a facial photograph of each inmate before discharge, available to the Department of Public Safety (690.4).
Changes, 2023 to 2026
Sexual assault kits kept at least 20 years, or for a minor victim’s lifetime; 60-day written notice before disposal
Law enforcement must store a kit for at least 20 years, up from 15, even if no criminal complaint is filed. For a minor victim, the period is now “the lifetime of the minor victim,” replacing 15 years after the minor reaches majority. Notice of intended disposal must now be in writing at least 60 days ahead; before, the notice had no set form or lead time. New sentence: “Upon written request of the reported victim, the law enforcement agency shall grant further preservation of the kit or its probative contents.” The county attorney’s written approval of disposal and the 48-hour kit-tracking documentation stay. The lab’s kit-tracking duties in 709.10(9) and (10) are unchanged.
For practitioners: Kits now stay available longer for later testing, including under Iowa Code 81.10; check whether a kit was disposed of without the 60-day written notice.
Medical examiner’s interagency coordinating council repealed
Section 368 repeals 691.6B as part of a consolidation of boards and commissions. The council’s duty was to “advise and consult with the state medical examiner” on the organization and effectiveness of the medical examiner system and on coordination with the departments of public safety and health and human services. Its members included the state medical examiner, the commissioner of public safety, the health and human services director, the governor, and representatives of the attorney general, county attorneys, the medical society, pathologists, county medical examiners, emergency medical services and funeral directors. Chapter 691 names no replacement body.
For practitioners: No standing multi-agency body now advises on Iowa’s death-investigation system.
Pending bills
No bill on these topics is pending. The 91st General Assembly adjourned in 2026, so its unenacted bills have died. The legislature’s bill list shows no effective date, and so no enactment, for these bills (91st General Assembly bills):
- HF 2624 (2026): DNA samples from people arrested for a felony or aggravated misdemeanor.
- SF 191 and HF 356 (2025): sexual assault kit testing, retention and inventory.
- HF 2 and HF 305 (2025): county medical examiner qualifications.
Checked and unchanged
- Iowa Code chapter 81 (DNA database and post-conviction DNA profiling): history lines end at 2019 Acts ch. 149. Iowa Code 822.2 and 822.3 (postconviction grounds and limitation): history lines end in 2019.
- Iowa Code 691.1 to 691.4 (criminalistics lab, presumption of qualification, evidence-handling rules, reports to the defendant): no amendment since 2019. 2023 Acts ch. 19 amended 691.5 to 691.7 only to rename the department of health and human services.
- Iowa R. Evid. 5.702: last amended effective January 1, 2017.
- IAC 661 chapters 150 and 156 were readopted in 2026. The prior rule text was not compared, so any substantive change is unconfirmed.
- No Iowa statute on rapid DNA, investigative genetic genealogy or digital forensics labs was found. Iowa Code 80.40 (Bureau of Cyber-Crime, 2021) authorizes “forensic analyses of criminal cases involving computer technology” and predates 2023. Outside this tracker’s scope: 2024 Acts ch. 1035 (fingerprint and palm-print submission, Iowa Code 690.2 and 690.5).
