Diamond Bar, California – Authorities have identified the woman who lost her life early Sunday morning in a multi-vehicle collision on the northbound Orange (57) Freeway in Diamond Bar.

According to the Los Angeles County Medical Examiner’s Office, the victim was 35-year-old Rosa Mejía, who was pronounced dead at the scene. Her city of residence has not been released.

The fatal crash occurred around 3:15 a.m., just south of the Pomona (60) Freeway interchange, the California Highway Patrol (CHP) reported. Firefighters and paramedics arrived shortly after and extricated Mejía from her vehicle at 3:25 a.m., according to the Los Angeles County Fire Department.

What to Do If Someone Dies in a Multi-Vehicle Collision – Compensation Guide

Losing a loved one in a multi-vehicle crash is one of the most devastating experiences any family can endure. Beyond the emotional toll, survivors are often left with unexpected financial burdens—medical bills, funeral expenses, and loss of income. Understanding your legal rights can help you pursue justice and the compensation your family deserves.

Understanding Wrongful Death Claims After a Fatal Car Accident

When someone dies in a crash caused by another driver’s negligence or recklessness, the surviving family members may be entitled to file a wrongful death claim. With the help of experienced wrongful death attorneys, families can seek compensation for economic and non-economic damages such as:

  • Funeral and burial costs
  • Lost financial support
  • Emotional suffering and loss of companionship
  • Medical expenses related to the crash

Wrongful death claims are civil actions separate from any criminal charges that may be filed against the at-fault driver.

How Liability Works in a Multi-Vehicle Collision

Determining fault in a multi-car crash is complex. Several drivers, or even a commercial vehicle company, could share responsibility for the chain of events. Police reports, eyewitness accounts, and accident reconstruction experts play a crucial role in identifying who is liable.

Working with experienced car accident lawyers in California ensures that all liable parties are held accountable, and that insurance companies don’t minimize or deny your rightful compensation.

What Compensation Can Be Claimed

Families may be able to recover compensation for:

  • Lost wages and benefits the deceased would have earned
  • Medical expenses prior to death
  • Funeral and burial costs
  • Loss of companionship, love, and guidance
  • Pain and suffering endured by the victim before death

Each case is unique, and settlement amounts depend on multiple factors including the severity of the crash, insurance coverage, and liability findings.
