If you were attacked, robbed or hurt by a crime on someone else's property, the records that usually matter fall into two groups. The first group shows what the owner knew about crime risks before the incident, such as earlier crime reports, complaints and guard logs. The second group shows the incident itself and the harm it caused, such as police and incident reports, video and medical records.

You may be reading this from a hospital bed, from a kitchen table covered in discharge papers, or as a family trying to understand how a parking lot, a hallway or an apartment door became the place where someone was hurt or killed. Most people facing this process have never had to think about guard logs or crime records before. They are trying to work out what exists, who has it, and what any of it means. This page walks through each kind of record in plain terms. It also explains what each record can show and what it cannot.

What Records and Evidence Matter in a Negligent Security Claim

A negligent security claim is a kind of premises liability claim. Premises liability is the area of law that covers injuries caused by conditions on someone else's property. In a negligent security claim, the harm comes from a crime that the property's owner or occupier is said to have failed to guard against reasonably. The claim rests on four elements:

  • a duty of care owed by the owner or occupier;
  • a breach of that duty;
  • causation, meaning a link between the breach and the harm;
  • damages, meaning the harm itself.

Whether those elements are met depends on the facts and the evidence. Our page on what an inadequate security lawsuit has to show explains those elements in more depth.

For someone who was hurt, the records sort into two piles. One pile shows what the owner knew about security risks before the incident. The other documents the incident and what it did to you or your family. The first pile often carries the most weight, because these claims often turn on what the owner knew or should have known. That makes the paperwork central to the case, not a side issue.

No single document decides fault or how a claim ends. What matters is what the records show when they are read together. A useful first question for anyone in this position is which of the two piles they already hold pieces of, and which sit with someone else.

Purpose: A Map of Who Holds What

This resource gives an injured person or a grieving family a map of the evidence in a negligent security case. It names each kind of record, who usually holds it, and which part of the claim it tends to bear on.

Many people already hold part of the picture without realizing it. Common examples include:

  • a police report number written on a card;
  • photos taken on a phone;
  • discharge papers from the emergency room;
  • messages to a property manager about a broken gate;
  • the names of neighbors, coworkers or other witnesses who saw something.

Other records sit with the property owner, a security company, a police department or a hospital.

What is at stake is that the pieces in your hands may be the ones no one else has kept. People in this position often gather what they have in one place and write down the names of anyone who saw what happened while memories are fresh. This resource cannot decide what the pieces add up to. That depends on the facts and on the law of the state where the case is brought. The background on how these cases work is covered on the negligent security lawyer overview.

Methodology: Why One State's Rule Is Only an Example

This resource is built from two legal sources. Each is used only for what it says.

The first is a 1998 decision of the Supreme Court of Texas, Timberwalk Apartments, Partners, Inc. v. Cain, 972 S.W.2d 749. It is used as one state's example of how a court weighs earlier crimes when deciding whether a later crime was foreseeable. Foreseeability means whether a reasonable owner could have anticipated the risk. Texas's rule is not the rule everywhere. Each state sets its own standard.

The second is Rule 37(e) of the Federal Rules of Civil Procedure. It covers lost electronically stored information, and it applies only in federal court.

Everything else on this page describes record types and what they can and cannot show. Limitation periods, fault rules and damages rules differ from state to state, and this page gives none of them as a universal rule. For a reader, the practical point is that the state where the incident happened shapes how every record below is weighed. Which state's law applies, and whether a case would be in state or federal court, is one of the questions an attorney can help sort out.

The record categories are set out below as steps, in the order the questions usually come up.

Step 1: Why What Happened Before Can Matter as Much as That Night

Whether a property owner had a duty to provide adequate security often depends on one question: was criminal activity on or near the property foreseeable? Foreseeability is typically shown through records of earlier incidents.

In Texas, the Timberwalk decision named five factors courts weigh when looking at earlier crimes:

  • proximity, meaning how close the earlier crimes were to the property;
  • recency, meaning how recently they happened;
  • frequency, meaning how often they happened;
  • similarity, meaning how much they resembled the incident at issue;
  • publicity, meaning how publicly known they were.

That is Texas's rule, cited here as one example. Other states apply their own standards to foreseeability and weigh earlier-crime evidence in their own ways.

Several kinds of records may bear on foreseeability:

  • police call logs and crime reports for the property and the surrounding area;
  • earlier incident reports filed by the owner or manager;
  • notices or complaints about security conditions, such as a tenant's written report of a broken lock.

For a family, this is often the hardest part to accept. The question is not only what happened that night. It is also what had happened before, and who knew about it. That makes these records some of the most contested in a case. A conversation with an attorney can help a person understand what earlier-crime records may exist and how that state's standard may treat them.

Step 2: What the Police and Incident Reports Can and Cannot Say About You

A police report typically records:

  • the date, time and location of the incident;
  • the names of the responding officers;
  • information about witnesses;
  • the officer's observations.

It is an official record of what was reported. It is not a finding of civil liability, meaning it does not decide who is legally responsible for the harm.

An incident report is different. It is filed by the property owner or manager and records the property's own account of what happened. Its contents, how complete it is, and when it was written can all be relevant. A report written days later, or one that leaves out a detail a witness remembers, may say something on its own.

What this means for an injured person is that the owner's version of events is on paper, and it may not match yours. Differences between the two reports, or between either report and what witnesses describe, can be significant. Neither document by itself establishes fault or a breach of duty.

Access procedures and retention timelines vary by jurisdiction and by agency. If you were hurt, the report number, the responding agency's name and the date are the details that usually make a later request possible. People often note where their own memory or a witness's account differs from what a report says, which is something an attorney can review alongside the reports.

Step 3: Camera Footage and Why It Disappears Quickly

Surveillance video can show what no report fully captures. Footage from a property's parking lots, entrances, hallways, elevators and common areas can show:

  • the lighting conditions;
  • whether security personnel were present;
  • the sequence of events before and during the incident.

Video from nearby businesses, traffic cameras or neighboring properties may also be relevant.

Security camera footage is typically recorded over on short cycles. Once it is overwritten, it cannot be recovered. How long any particular system keeps its footage depends on that system.

Injured people and families often note where cameras were mounted and which neighboring businesses face the scene. A lawyer for an injured person can also send the property owner a preservation demand, which is a written request to keep the footage. A separate page on this site covers the steps involved in preserving camera video and records before they are erased.

Step 4: What Guard Logs and Repair Records Can Reveal About a Security Gap

If a gate, lock or light was broken when you were hurt, the property's maintenance records may show it. These records can show whether gates, door locks, exterior lighting, fencing and intercom systems were working at the time of the incident, and how recently they had been inspected or repaired. A work order for a broken gate light, and the date it was closed, can matter.

When a property hires a guard or patrol company, the security contract sets out what services were required. Guard logs and shift records show what was actually done. Gaps between the two can be significant. For example, the contract may call for patrols at set hours while the logs show fewer patrols, or none on the night in question. If the logs show no patrols on the night you were hurt, that gap can bear directly on whether the owner did what the contract required.

These records are held by the property owner or the security contractor, not by the injured person. They are typically obtained through discovery once a lawsuit begins. Discovery is the formal court process in which each side must exchange relevant records. Before a lawsuit is filed, a lawyer for the injured person can send a preservation demand asking that these records be kept. What you can contribute now is what you saw yourself: a light that had been out for weeks, a gate that never latched, or a message you sent the manager about it.

Step 5: What Your Medical Records Prove — and What They Do Not

Your medical records are the main account of what the incident did to you. They include emergency room and hospital records, records from treating physicians, physical therapy notes, and records of any ongoing care. Together they show the nature of the injuries, the treatment received, and the timeline of recovery. After a death, records of the final care can be part of the same picture.

These records show what injuries were treated and when. They do not by themselves show that the property owner's conduct caused the incident. That question belongs to the other categories on this page.

Damages in a negligent security case are set by the law of the state where the case is brought, and what may be available differs from state to state. If you are still in treatment, the records are still being written. People in that position often keep discharge papers, appointment summaries and billing statements together as they arrive. How those records relate to the damages rules in a given state is something an attorney can help explain.

Step 6: What Happens to Evidence When Records Are Lost or Destroyed

Spoliation is the loss, destruction or alteration of evidence that was relevant to a lawsuit that was pending or reasonably expected.

In federal court, Rule 37(e) of the Federal Rules of Civil Procedure covers electronically stored information, such as digital video or electronic logs. It applies when that information should have been preserved in anticipation of litigation or during it, was lost because a party failed to take reasonable steps to preserve it, and cannot be restored or replaced through additional discovery. If the court finds the other side was prejudiced by the loss, it may order measures no greater than necessary to cure that prejudice. The rule allows stronger measures only if the court finds the party acted with the intent to deprive another party of the information's use. Those stronger measures are:

  • presuming the lost information was unfavorable to that party;
  • instructing the jury that it may or must presume this;
  • dismissing the action or entering a default judgment.

That rule governs federal court only. State courts have their own rules on lost or destroyed evidence, and those rules differ from state to state.

When evidence is lost after a party had a duty to preserve it, a court may impose sanctions, give an adverse inference instruction, or take other measures. An adverse inference instruction tells the jury it may assume the missing evidence would have hurt the side that lost it. What a court actually does depends on the circumstances and the rules that apply. No particular result is assured. For an injured person, this is why a preservation demand sent early can matter: it helps show when the other side was on notice.

Step 7: Questions Worth Asking Before the Evidence Picture Is Complete

The evidence picture in a negligent security case is rarely complete at the start. Some records are with the injured person. Others are held by the property owner, a security contractor, a police department or a hospital.

Questions that often come up at this stage include:

  • What records exist, and where are they held?
  • Are any of them at risk of being lost or overwritten?
  • Who saw what happened, and how can they be reached?
  • What is the limitation period in the state where this happened, and when does it begin to run?
  • What may the evidence show about the owner's knowledge of earlier security risks?

A limitation period, also called a statute of limitations, is the deadline for filing a civil claim. These deadlines differ by state. The clock often begins on the date of the injury or death, and states have their own exceptions. People at this point often find it helpful to talk through which deadline applies in their state and which records are still out of reach. If that is where you are, you may want to consider requesting a case evaluation to discuss those dates and records.

Interpretation: Reading Your Records as an Inventory

This resource is best read as an inventory, not a scorecard. Each category above links to one part of the claim:

  • earlier crime records to foreseeability and duty;
  • maintenance records, contracts and guard logs to breach;
  • reports, video and witness accounts to how the incident unfolded and to causation;
  • medical records to the harm.

An empty space in one category does not mean a claim fails. A full category does not mean it succeeds. A missing guard log, for example, may simply not have been requested yet. A long list of earlier crimes may carry more or less weight depending on the state's standard and how similar those crimes were.

If you hold only a few pieces, that is common at this stage. Seeing which categories are empty and who holds those records is part of the point, and it gives a clear starting list for a conversation with an attorney. More plain-language answers are collected on our common questions page.

Limitations

This resource does not determine fault, liability, a deadline, or what a claim is worth. It does not say whether a duty existed in a particular case, whether it was breached, or whether a breach caused the harm.

It cites one Texas decision as an example and does not state the foreseeability standard of any other state. It states no limitation period, no video retention period, and no damages rule.

It cannot say whether a particular record still exists or how a particular court would treat a lost one. How these cases can end, from dismissal to verdict, is described on our page on how negligent security claims end. That page also does not predict any one result.

Frequently asked questions

What documents are most important in a negligent security case?

The core categories are police reports, the property's incident reports, surveillance footage, maintenance and inspection records for security equipment, security contracts and guard logs, records of earlier crimes on or near the property, and medical records. No single document is decisive. What the evidence shows when read together is what matters.

How does prior crime history affect a negligent security claim?

Earlier crime history bears on whether criminal activity was foreseeable to the property owner, which is a central question in most of these cases. In Texas, the Timberwalk decision weighs proximity, recency, frequency, similarity and publicity. Other states apply their own standards. Earlier crimes alone do not prove liability.

Who holds the records in a negligent security case?

Records are spread across several holders. The injured person or family has medical records and photos. The owner or manager has incident reports, maintenance logs and contracts. The security contractor has guard and patrol logs. Police hold reports and crime logs. Neighbors or traffic agencies may hold video. Owner-held records typically come through discovery.

What is spoliation and why does it matter?

Spoliation is the loss, destruction or alteration of evidence relevant to a pending or expected lawsuit. In federal court, Rule 37(e) of the Federal Rules of Civil Procedure covers lost electronically stored information. State courts have their own rules. Depending on the circumstances, a court may impose sanctions or give an adverse inference instruction.

Does a police report prove that a property owner was negligent?

No. A police report is an official record of what was reported and observed. It does not establish civil liability or that the owner breached a duty of care. Whether the elements of a claim are met depends on all of the evidence and the law of the state where the case is brought.

Do limitation periods for negligent security claims differ by state?

Yes. Limitation periods, the deadlines for filing a civil claim, are set by state law and differ from state to state. The clock often starts on the date of the injury or death, but exceptions and tolling rules vary. Tolling means pausing or extending the deadline. This page states no specific period.

What role does surveillance footage play in these cases?

Footage can show lighting, whether security personnel were present, and the sequence of events before and during the incident. It is typically recorded over on short cycles and cannot be recovered once overwritten. A separate page on this site covers preserving video, and this page gives no retention period.

What do maintenance records show in a negligent security case?

They can show whether gates, locks, lighting and other security equipment were working, and how recently they were inspected or repaired. Gaps between what a security contract required and what the logs show was done can be significant. The property owner usually holds these records, and they typically come through discovery.
