Questions Families Ask Us After a Wrongful Death
What Missouri and Illinois Families Need to Know
Types of Wrongful Death Cases We Handle
We represent families in a wide range of wrongful death claims, including:
Fatal car, truck, and motorcycle accidents
Losing a loved one in a car, truck, or motorcycle accident is devastating, especially when the crash was caused by another driver’s negligence. These collisions often result from speeding, distracted driving, or reckless behavior, leaving families with emotional grief and financial hardship. Wrongful death claims can help recover compensation for medical expenses, funeral costs, and lost income. Having once defended insurance companies, we know the tactics they use to minimize payouts. Our firm builds strong cases that prove liability, hold negligent drivers accountable, and provide surviving families with the justice and financial security they deserve during an incredibly difficult time.
Dangerous property conditions (slip/trip and fall deaths)
Falls caused by unsafe property conditions can be deadly, particularly for elderly victims or those with health vulnerabilities. Property owners have a duty to maintain safe conditions by fixing hazards like broken stairs, uneven sidewalks, poor lighting, or wet floors. When they fail in this duty and a fatal accident occurs, surviving families deserve justice. These cases are often complex, as insurers try to argue that the hazard was “open and obvious” or that the victim was at fault. Our firm knows how to counter these defenses and build strong claims that hold negligent property owners fully accountable.
DUI and reckless driving deaths
Drunk and reckless drivers endanger everyone on the road, and too often their choices result in fatal accidents. Families who lose loved ones in these preventable crashes are left with unimaginable grief and financial burdens. While the criminal system may punish the driver, it does not provide compensation for survivors. That’s where a wrongful death claim becomes critical. Our firm knows how to pursue civil damages against reckless drivers and their insurers, ensuring families receive financial support for medical bills, lost income, and future stability. We fight tirelessly to hold dangerous drivers fully accountable for their devastating actions.
Commercial vehicle and delivery truck crashes
Commercial vehicle and delivery truck accidents are often catastrophic, given the size and weight of the vehicles involved. When negligence by a company driver or poor fleet management causes a fatal crash, the consequences for surviving families are overwhelming. Trucking and delivery companies typically have powerful insurers who fight hard to avoid responsibility. With our experience defending businesses in these cases, we know the strategies they use to deny liability. Our firm investigates thoroughly, examining driver records, company policies, and vehicle maintenance to build a compelling wrongful death claim that holds negligent companies accountable and delivers justice for grieving families.
Construction and workplace fatalities
Construction sites and other workplaces can be dangerous when safety regulations are ignored. Fatal workplace accidents often result from falls, defective equipment, lack of protective gear, or unsafe practices. Families left behind not only lose a loved one but may also struggle with financial instability. Workers’ compensation benefits may not cover the full loss, making third-party wrongful death claims critical. With our background in defending these cases, we know how companies and insurers attempt to minimize payouts. We pursue every available avenue to ensure families receive the justice and compensation they deserve after a preventable workplace tragedy.
Medical negligence resulting in death
When medical professionals fail to provide proper care, the consequences can be tragic. Fatal medical negligence may involve surgical errors, misdiagnosis, medication mistakes, or failure to monitor patients correctly. Hospitals and providers often have strong legal teams working to avoid liability, leaving families struggling for answers. With our knowledge of how insurers and defense attorneys approach these cases, we build detailed wrongful death claims backed by expert testimony. Our firm fights to hold negligent medical providers accountable, helping families find justice and financial security after the devastating and preventable loss of a loved one due to medical malpractice.
Pedestrian and bicycle fatalities
Pedestrians and cyclists are especially vulnerable in collisions with motor vehicles, and these accidents are often fatal. Whether caused by distracted drivers, speeding, or failure to yield, these crashes leave families reeling from preventable loss. Insurance companies frequently attempt to shift blame to the victim, arguing that they were inattentive or outside a crosswalk. We know how to counter those arguments and prove negligence through evidence like surveillance footage, accident reconstruction, and witness statements. Our firm fights tirelessly to hold reckless drivers accountable and to secure the compensation families need after losing a loved one in a pedestrian or bicycle accident.
Nursing home neglect or abuse
Families place immense trust in nursing homes to care for their loved ones. When that trust is broken and a resident dies due to neglect or abuse, the pain is immeasurable. Fatalities in nursing homes may result from falls, untreated infections, medication errors, or outright abuse. Facilities often deny wrongdoing and attempt to shift blame onto residents. Our firm knows how to uncover evidence of neglect and hold nursing homes accountable. We fight for justice for families and dignity for victims, ensuring that negligent facilities are exposed and that survivors receive compensation for their heartbreaking and preventable loss.
Uninsured and underinsured motorist death claims
When a loved one is killed by an uninsured or underinsured driver, the path to justice often depends on UM/UIM coverage. These claims can provide critical compensation for funeral expenses, medical bills, and loss of financial support. Unfortunately, insurers often delay or dispute payment, arguing that coverage doesn’t apply or minimizing the value of the claim. With our experience defending insurance companies, we know their tactics and how to counter them. Our firm builds strong UM/UIM wrongful death cases, ensuring grieving families receive the compensation they deserve when a negligent, uninsured, or underinsured driver causes a fatal crash.
Fatal injuries from defective products
Defective products—from unsafe machinery to faulty medical devices—can cause fatal injuries when manufacturers fail to prioritize consumer safety. These wrongful death cases often involve complex evidence, technical testimony, and powerful corporations fighting to avoid liability. Survivors are left grieving and searching for accountability. Our firm investigates design flaws, manufacturing errors, and failures to warn consumers of risks, building strong claims against negligent manufacturers. With our background in defending companies, we know how they approach these cases—and how to beat them. We fight to hold corporations accountable when defective products cause fatal injuries, securing justice for grieving families.
