Detailed Answer
This article explains the types of evidence that typically prove an assault claim under Nebraska law, how each item helps either a criminal or civil case, and practical steps to preserve evidence. This is a general guide and not legal advice.
Legal context in Nebraska
In Nebraska, criminal assault is defined and punished in the criminal code (see Chapter 28 of the Nebraska Revised Statutes). Penalties depend on the degree and circumstances. For an overview of the statutes, see the Nebraska Legislature’s Chapter 28 of the Revised Statutes: Neb. Rev. Stat. Chapter 28. The rules of evidence that apply in court come from Nebraska’s evidence rules and case law (see Chapter 27): Neb. Rev. Stat. Chapter 27 (Evidence).
Burden of proof: criminal vs. civil
- Criminal case: The state must prove the defendant’s guilt beyond a reasonable doubt. This is a high standard.
- Civil case (assault/tort claim): The plaintiff must prove liability by a preponderance of the evidence — meaning it is more likely than not that the assault occurred.
Types of evidence that matter and why
Different items of evidence serve different purposes. Use as many of these as you can collect and preserve.
1. Witness testimony
Eyewitnesses (bystanders, friends, employees) can describe the events, who started the incident, and how it unfolded. Consistent, credible witness statements strengthen both criminal and civil cases.
2. Victim’s testimony
The injured person’s sworn account is central. Expect cross-examination on memory, consistency, and possible bias. Detailed notes made soon after the event help refresh memory.
3. Photographs and video
Photos of injuries, the scene, torn clothing, blood, broken property, and timestamps on phone or security footage are highly persuasive. Video surveillance, dash cams, or doorbell cameras often provide objective timelines and show actions and intent.
4. Medical records and forensic exams
Medical notes, emergency room charts, imaging (X-rays, CT), photographs taken by medical staff, and forensic sexual assault exams (when applicable) document injuries, their severity, and timing. These records can link injuries to the incident and rebut claims that injuries were preexisting.
5. Police reports and 911 recordings
Police reports record statements, observations, and initial evidence collected. 911 call recordings preserve urgent statements, background noise, and timing. While a police report is not itself the final proof, it is an important contemporaneous record.
6. Physical evidence
Clothing, weapons, damaged property, or biological evidence (blood, hairs) can be preserved and tested. Forensic testing (DNA, fingerprints) can directly connect a defendant to the scene.
7. Electronic evidence
Texts, emails, social media messages, call logs, and geolocation data can show threats, admissions, movements, or intent. Screenshots alone may be challenged; preserve original files and metadata when possible.
8. Expert testimony
Medical experts can explain injuries and causation. Forensic experts can explain lab results, and use-of-force or reconstruction experts can interpret events. Experts translate technical evidence into clear courtroom testimony.
9. Prior threats, domestic history, and pattern evidence
Past threats, stalking, or prior abusive incidents can support claims of intent or motive. Admissibility is limited by rules against unfairly prejudicial evidence, but such evidence may be allowed when it explains context or establishes a pattern.
What proves an assault in practice?
Courts look at the entire evidentiary picture. No single type of evidence is required, but cases are stronger when multiple forms align:
- Immediate medical records showing fresh injuries + photos taken soon after.
- Video or eyewitnesses corroborating the victim’s account.
- Text messages or recorded threats showing intent followed by a physical act.
- Physical evidence (weapon, blood) connecting the defendant to the assault.
In criminal cases, the state must exclude reasonable doubt; in civil cases, consistent documentation and corroboration can tip the balance in the plaintiff’s favor.
Common defenses and how evidence addresses them
- Self-defense: The defendant claims they acted to protect themselves. Evidence that rebuts this includes witness testimony, video showing the defendant as the aggressor, medical records inconsistent with the defendant’s version, and lack of provocation.
- Consent: In some contexts, consent may be raised. Evidence like contemporaneous communications or third-party testimony can establish or refute consent.
- Mistaken identity: Surveillance, location data, and forensic evidence can establish who was present.
How to preserve evidence right away
- Get medical care immediately. Ask for written records and photographs of injuries.
- Take your own photos and videos of injuries and the scene, with visible date/time when possible.
- Do not wash or discard clothing; place items in a paper bag (not sealed plastic) and keep them for testing.
- Save electronic communications and back them up. Preserve voicemail, text messages, social posts, and screenshots with metadata where feasible.
- Write a contemporaneous account—dates, times, sequence of events, and names of witnesses.
- Get witness names, phone numbers, and brief written statements if they’ll provide them.
- Report to police if you want criminal investigation and ask how evidence will be collected and stored.
- Limit contact with the alleged assailant; avoid discussing details publicly that could affect testimony.
Working with police, prosecutors, and attorneys
File a police report if you seek criminal charges. Share all evidence and witnesses with investigators. If prosecutors pursue charges, they will evaluate whether evidence meets the burden beyond a reasonable doubt. For civil claims, an attorney can help preserve evidence through subpoenas, coordinate discovery, and consult experts.

When to consult an attorney
Talk to an attorney as soon as you can if you face ongoing danger, want to pursue civil damages, have conflicting witness accounts, or the other party denies the facts. An attorney can guide evidence collection, preserve chain of custody for physical items, arrange expert review, and advise about timing, statute of limitations, and filing options.
