Prosecutions under Article 120 of the Uniform Code of Military Justice, 10 U.S.C. 920, often rely on physical evidence gathered through a sexual assault forensic examination. The kit produced by that examination, commonly called a SAFE kit, passes through many hands between collection and a possible court-martial. The procedures that govern its collection and custody come from two overlapping sources: the Department of Defense sexual assault prevention and response framework, which controls how evidence is collected and stored, and the military rules of evidence, which control whether the kit can ultimately be admitted at trial. Understanding both is essential, because a kit can be collected perfectly under the policy framework and still be challenged on chain-of-custody grounds in the courtroom.
The reporting framework that shapes collection
Collection in the military begins with the victim’s reporting choice. The Department of Defense sexual assault prevention and response policy recognizes two options. Unrestricted reporting notifies command and law enforcement and allows a full investigation. Restricted reporting allows a victim to receive medical care, advocacy, and a forensic examination confidentially, without triggering an investigation, unless an exception applies. This choice directly affects the evidence. The standardized forms used in the process include a victim reporting-preference statement and a forensic examination report. Under the policy framework, the kit and associated evidence in a restricted report are stored for a defined retention period, generally five years, while the examination report itself is retained for a much longer period, reflecting the possibility that a victim may later convert a restricted report to an unrestricted one and pursue the case.
This framework matters for Article 120 cases because the path the evidence takes, and how long it is held, depends on whether the report was restricted or unrestricted at the time of collection. A kit collected under a restricted report is not handed to investigators unless and until the victim changes that election or an exception applies.
How the examination and collection are conducted
The forensic examination is performed by trained medical personnel, often a sexual assault nurse examiner, using a standardized kit and protocol. The examiner documents history, observations, and findings on the prescribed forensic examination report and collects biological and trace evidence in sealed, labeled containers within the kit. The examination may occur at a military treatment facility or, where the service has an agreement with a civilian facility, at that civilian site. When a civilian facility conducts the examination under a memorandum of understanding or agreement with the Department of Defense, that agreement is required to address how the kit will be handled and how custody will be transferred to the appropriate military authority, including contact with the installation sexual assault response coordinator.
Proper labeling and sealing at the point of collection is the foundation of everything that follows. Each item is sealed, initialed, and dated, and the examiner records what was collected. The integrity of those seals is one of the first things scrutinized later.
Chain of custody from collection to court
Chain of custody is the documented, unbroken record of who had the evidence, when, and what they did with it, from collection through analysis to trial. After collection, the kit is transferred to the custody of the appropriate authority, typically military criminal investigators in an unrestricted case or secure storage in a restricted case. Each transfer is logged. When the kit moves to a forensic laboratory for analysis, the receiving and returning of the evidence are again documented, and the laboratory maintains its own internal custody records. The aim is a continuous paper trail in which every person who handled the kit can be identified and every transfer accounted for.
A meaningful gap in that record, an unexplained period during which the location or custodian of the kit is unknown, or evidence that a seal was broken without explanation, is the kind of problem that becomes a litigation issue. The policy framework is designed to prevent such gaps by requiring logged transfers and secure storage at every stage.
How chain of custody becomes an evidentiary question at trial
Collecting and storing the kit correctly is necessary but not sufficient. To use the kit at a court-martial, the government must satisfy the military rules of evidence. Authentication under Military Rule of Evidence 901 requires the proponent to produce evidence sufficient to support a finding that the item is what it is claimed to be. For physical evidence like a SAFE kit, the chain of custody is the usual way to authenticate, by accounting for the evidence from collection to courtroom so the court can be confident it was not confused with another item or altered.
The legal standard is often misunderstood. A perfect, gap-free chain is not always required for admission. Where evidence has unique characteristics or is readily identifiable, minor gaps generally go to the weight the factfinder gives the evidence rather than to its admissibility, and a presumption of regularity attaches to evidence kept in official custody. But the more fungible the material and the more serious the gap or the sign of tampering, the more likely a military judge is to exclude it or to require additional foundation. Laboratory results carry their own layer, because the analyst’s testimony or a proper certification, and confrontation considerations, may be required to admit the findings.
How the defense tests the kit
Defense counsel routinely examine the chain-of-custody documentation for unexplained gaps, broken or missing seals, inconsistencies between the collection record and the laboratory record, and storage conditions that could degrade or contaminate samples. These challenges may support a motion to exclude the evidence or, more often, an argument to the panel that the kit deserves little weight. Counsel may also scrutinize whether the examination followed the standardized protocol and whether the forms were completed accurately.
Bottom line
The collection and chain of custody of a sexual assault kit in an Article 120 case are governed first by the Department of Defense sexual assault prevention and response framework, which dictates how the examination is performed, how evidence is sealed and stored, how restricted and unrestricted reports route the kit, and how custody transfers, including those involving civilian facilities, are documented and retained. They are governed second by the military rules of evidence, principally MRE 901 authentication, which determine whether the kit can be admitted at trial. A kit that is collected, sealed, transferred, and stored according to the policy, with a continuous and documented chain, is the kind of evidence that survives a courtroom challenge. Gaps, broken seals, or undocumented transfers do not automatically exclude the kit, but they give the defense grounds to attack either its admissibility or the weight it should receive.
