Negligent Security Attorney in Sedalia, Missouri

Missouri’s Business Premises Safety Act

The primary statute governing negligent security claims against businesses in Missouri is the Business Premises Safety Act, codified at §§ 537.785 and 537.787, effective August 28, 2018. Understanding what the Act requires and what it doesn’t shapes how these cases are built and defended.

Under the Act, a business has no duty to guard against criminal acts unless it knows or has reason to know that such acts are being committed or are reasonably likely to be committed on a particular area of the premises, and sufficient time exists to prevent the crime or injury. That foreseeability standard is the threshold question in most claims.

Evidence used to establish foreseeability includes:

• Prior criminal incidents on or near the property
• The nature of the business, such as late-night hours, cash handling, or alcohol service
• Complaints from customers or employees about safety conditions
• Industry knowledge about security risks for that property type

A business can defend against a claim by demonstrating it implemented reasonable security measures, or by showing the victim was trespassing or attempting to commit a felony at the time of the incident. Evidence of security improvements made after an incident isn’t admissible to prove negligence or to establish that improvements were feasible.

The Act excludes commercial residential and lodging operations from its definition of “business.” Apartment complexes and hotels may therefore face broader common law premises liability standards rather than the Act’s specific framework.

Statutes of limitations: For a personal injury negligent security claim, Missouri generally allows five years from the date of injury under § 516.120, though exceptions may apply. A wrongful death claim carries a three-year period from the date of death under § 537.080.

Common Security Failures in Negligent Security Claims

When evaluating whether a property owner breached the duty of care, courts and juries focus on the specific conditions that existed at the time of the incident. Several failures appear repeatedly in these cases.

Inadequate Lighting
Dark parking lots, unlit stairwells, dim hallways, and poorly lit building exteriors create conditions that invite criminal activity and are among the most common and hardest-to-defend security failures.

Non-Functional Surveillance Systems
Cameras with dead zones, systems that overwrite footage before it can be preserved, or entirely absent video monitoring constitute a security failure, particularly at properties with a history of incidents.

Absent Security Personnel
At bars, nightclubs, and late-night retail locations with a known history of criminal activity, the absence of security staff or de-escalation protocols is a recurring basis for claims.

Broken Access Controls
Non-functioning locks, gates, and entry control systems at apartment buildings, hotels, and gated properties create foreseeable conditions for criminal activity against residents and guests.

Failure to Act on Known Crime History
A property owner who is aware of prior criminal incidents and takes no corrective action provides strong evidence of foreseeability in a negligent security case.

The Four Elements of a Missouri Negligent Security Claim

To recover compensation, a victim must establish four elements. Each requires evidence, and the strength of that evidence affects the value and viability of the claim.

Duty: The property owner owed a duty of care to the victim as a lawful visitor, customer, guest, or tenant.

Breach: The property owner failed to provide adequate security despite knowing or having reason to know that criminal activity was likely on the premises.

Causation: The inadequate security directly contributed to the crime. A victim doesn’t need to prove that better security would have guaranteed safety, only that reasonable measures would have reduced the likelihood of the attack.

Damages: The victim suffered actual harm, including physical injuries, emotional trauma, financial losses, or the death of a family member.

Missouri follows a pure comparative fault rule. A victim’s compensation is reduced by their percentage of fault but isn’t eliminated, even if they bear some share of responsibility for what occurred. Building a strong case typically requires police reports, prior incident histories, security industry analysis, and crime data for the surrounding area.
