When your Texas negligent security case requires expert analysis, you need someone who can evaluate the evidence and explain the findings clearly. When the claim involves an alleged failure to protect against third-party criminal conduct, that analysis may also include the Timberwalk factors.
SSMC assists plaintiff and defense attorneys with crime-data review, security adequacy analysis, causation issues, expert reports, depositions, and trial testimony.

How Attorneys in Texas Cases Typically Use Expert Witnesses
A security expert may assist at several stages of a Texas case, including:
- Preliminary case evaluation
- Identification of security-related issues
- Review of crime and incident data
- Timberwalk foreseeability analysis when third-party criminal conduct is at issue
- Evaluation of security policies and practices
- Site inspections
- Expert reports and disclosures
- Rebuttal analysis
- Deposition preparation and testimony
- Trial support
When should you involve an expert?
Earlier is usually better. Video, access-control records, and physical conditions may change or disappear after an incident. Early involvement helps preserve the evidence and supports a more complete analysis.
Texas Negligent Security and Timberwalk
In Texas negligent security cases alleging a failure to protect against third-party criminal conduct, foreseeability may be evaluated under the framework established in Timberwalk Apartments, Partners, Inc. v. Cain.
Under that framework, courts may consider five factors:
- Proximity: Did previous crimes occur on or near the property?
- Recency: How recently did those crimes occur?
- Frequency: How often did comparable incidents happen?
- Similarity: Were the earlier crimes sufficiently similar to the incident at issue?
- Publicity: Did the property owner know, or have reason to know, about them?
These factors are considered together. A crime map, police report, or general crime statistic does not answer the foreseeability question by itself.
The information must be connected to the property, the relevant time period, the type of criminal activity, and what the property owner knew or reasonably should have known.
The Timberwalk factors address foreseeability. They do not automatically determine whether a risk was unreasonable or establish the full scope of a property owner’s legal duty.
What does that mean in practice?
Crime data needs context. So do security recommendations.
How a Texas Negligent Security Expert Can Help
A negligent security expert helps counsel evaluate the property conditions, security measures, and causation issues involved in the case. When the claim concerns third-party criminal conduct, the expert may also analyze relevant crime history and the Timberwalk factors.
The expert may review:
- Crime and incident data for the property and surrounding area
- The relevance of prior incidents under the Timberwalk factors, when applicable
- Lighting, access control, surveillance, locks, gates, and doors
- Security staffing, patrol practices, and post orders
- Policies, training, reporting, and incident-response procedures
- Whether security measures were maintained and followed
- Whether additional reasonable measures may have deterred the crime or reduced the harm
- Whether an alleged security deficiency contributed to the incident or injury
The analysis should fit the property and the facts. A hospital, apartment community, hotel, retail center, or parking facility will not present the same risks or require the same security practices.
In Texas cases alleging a failure to protect against third-party criminal conduct, the expert analysis may focus on three questions:
- Was the crime reasonably foreseeable under Timberwalk?
- Were reasonable security measures missing or inadequate?
- Did an identified security deficiency contribute to the occurrence or severity of the crime?
The expert does not decide whether a legal duty existed. That remains a question for the court.
Instead, the expert evaluates and explains the security evidence so counsel, the court, and the trier of fact can better understand the issues.

Choosing the Right Expert Witness in Texas
The right expert is not simply the person with the longest résumé.
It is the person whose experience matches the property, the security issues, and the work required.
Match the Expert to the Property Environment
Security expectations vary by property type.
An apartment community does not operate like a hospital. A hotel has different access and staffing concerns than a warehouse. A retail parking lot presents different challenges than a college campus.
The expert should understand:
- How the property operates
- Who uses it
- How people enter and leave
- What staff members are expected to do
- Which security measures were in place
- Whether those measures worked as intended
- What practical limitations affected the operation
SSMC evaluates security matters involving hospitals, hotels, apartments, retail properties, schools, workplaces, warehouses, entertainment facilities, parking areas, and other commercial environments.
Communication in Depositions and Trial
An expert may understand the subject and still struggle as a witness.
A testimony-ready expert should speak plainly, answer the question asked, avoid speculation, and acknowledge reasonable limitations. They should also understand the difference between a security opinion and a legal conclusion reserved for the court.
Look for a Clear and Defensible Method
A reliable expert should be able to explain:
- What evidence was reviewed
- Which records were unavailable
- How relevant crime data was selected
- How the Timberwalk factors were evaluated, when applicable
- Which security practices apply
- What assumptions were made
- How the evidence supports the conclusions
The opinion should not begin with the desired result and work backward.
It should begin with the facts.
Red Flags When Hiring a Texas Security Expert
Be cautious when an expert:
- Guarantees a favorable result
- Reaches conclusions before reviewing the evidence
- Treats all nearby crime as equally relevant
- Uses the same crime-data radius in every case
- Relies on vague references to “best practices”
- Ignores the property’s actual operation
- Recommends security measures without connecting them to the incident
- Cannot explain how an alleged deficiency affected the outcome
Confidence is valuable. Overreach is not.
Questions to Ask Before Retaining a Texas Security Expert Witness
A few strategic questions can help you determine whether the expert fits the case:
- What experience do you have with Texas negligent security matters?
- When third-party criminal conduct is at issue, how do you approach Timberwalk and crime-data analysis?
- Have you evaluated a similar property or security operation?
- What records do you need before forming preliminary opinions?
- Is a site inspection likely to add value?
- Are you available for the applicable disclosure, deposition, and trial dates?
You should also ask how the expert handles missing or disputed evidence.
A credible opinion should clearly separate confirmed facts, assumptions, limitations, and unresolved questions.

Role of a Negligent Security Expert Witness
In a Texas negligent security case, an expert witness typically evaluates:
- Historical crime data for the property and surrounding area.
- Whether the crime pattern satisfies the Timberwalk factors.
- Industry standards and customary security practices.
- Existing security measures (lighting, access control, surveillance, guards, locks, gates, policies, and procedures).
- Whether reasonable security measures would likely have deterred or reduced the risk of the incident.
- Causation between alleged security deficiencies and the plaintiff’s injury.
The expert’s analysis generally focuses on three questions:
- Was the crime foreseeable under Timberwalk?
- Were reasonable security measures absent or inadequate?
- Did those deficiencies contribute to the occurrence or severity of the crime?
Texas courts frequently rely on expert testimony to evaluate adequacy of security.

Expert Witness in Texas FAQs
The Timberwalk factors are proximity, recency, frequency, similarity, and publicity. Texas courts consider them together when evaluating whether third-party criminal conduct was reasonably foreseeable.
The analysis is more detailed than simply counting crimes in a ZIP code or drawing a standard radius around a property.
Begin with a concise case summary, the pleadings, incident reports, available video, property photographs, relevant policies, and the current expert deadlines.
The expert can then identify additional records that may be needed, such as crime data, calls for service, access-control logs, guard reports, or maintenance records.
No. Many cases can begin with a remote records review.
An inspection may become important when the analysis depends on lighting, gates, doors, camera views, sightlines, parking configurations, patrol routes, or other physical conditions.
The expert should also determine whether the property has changed since the incident.
Early involvement can help identify relevant evidence, shape document requests, and prevent avoidable delays.
It becomes especially important when surveillance video, electronic records, or physical conditions may not remain available.
Yes. SSMC accepts appropriate engagements from plaintiff and defense counsel. The same analytical process applies to both sides: review the evidence, identify the relevant security issues, and develop opinions that can be supported.
No. A security expert may evaluate crime data, security practices, property conditions, and causation-related facts. The court determines the existence and scope of a legal duty.
A Texas security expert witness must be qualified through knowledge, skill, experience, training, or education. The testimony must also help the judge or jury understand the evidence and be relevant, reliable, and supported by sufficient facts and a defensible method.
Relevant qualifications may include experience with security operations, physical security, crime-data analysis, policies and procedures, staffing, incident response, and expert testimony. Texas courts may also consider the reliability principles established in Robinson and related cases when evaluating the expert’s opinions.
