Kasey Grelle, 41-year-old CEO and founder of a St. Louis-based marketing consulting firm Aux Insights, died in a horrific car crash while vacationing with her family in Nicaragua. The incident also left her 11-year-old son, Julian, critically injured and hospitalised.

According to a report by the New York Post, the incident took place on March 23 inside the Rancho Santana resort complex in Tola, along Nicaragua’s southwest coast. Grelle was travelling in an open-air tourist transport truck with her family and other passengers when the vehicle lost control while descending a hill and flipped over.
The crash reportedly injured more than 20 people, including children, with around 28 foreign passengers on board. Emergency responders and resort staff rushed victims to the Hospital Gaspar García Laviana in Rivas. Grelle, who suffered severe head trauma and a skull fracture, died while being transported to the hospital.
Her 11-year-old son, Julian, was critically injured in the crash and later airlifted to a hospital in St. Louis. According to a GoFundMe page shared by the family, he suffered multiple serious injuries, including head trauma, skull and spine fractures, and a collapsed lung.
Grelle is survived by her husband, Dave, and their three children — Julian, 11; Kit, 9; and Des, 6.
In a heartfelt Facebook post, her brother Andy Joyce remembered Grelle as “one of the most brilliant, driven and selfless people I have ever met and she was relentless in everything she did, especially when it came to helping her people.”
“We are heartbroken for David Grelle, Julian, Kit and Des as well as everyone else who knew and loved Kasey,” he added.
