Kyle Busch‘s newly released death certificate is shedding more light on his sudden and tragic passing at the age of 41.
Two-time NASCAR Cup Series champion Kyle Busch died on May 21st, just hours after his family announced he’d been hospitalized with “a severe illness.”
After Kyle passed away, his family released a statement confirming his cause of death. He developed pneumonia, which progressed into sepsis, leading to a series of complications and Kyle’s eventual passing.
More recently, Us Weekly obtained a copy of Kyle’s death certificate, which reveals new information about his health prior to his death.
In a report published on Wednesday (May 27th), Us Weekly claims Kyle’s death certificate outlines a “chain of events” that unfolded before he passed away.
As Us Weekly details, the death certificate says everything began with a case of bacterial pneumonia, which Kyle battled for “days to weeks.”
Then, the pneumonia progressed into sepsis. The medical examiner found that Kyle likely had sepsis for just one day before he died, but things rapidly took a turn for the worse.
The sepsis caused disseminated intravascular coagulation. The Cleveland Clinic describes it as a rare blood-clotting disorder that can occur in septic patients.
This condition caused Kyle to suffer from hemorrhagic shock, which happens when someone experiences extreme internal or external blood loss. This devastating sequence of events led to Kyle’s death.
The NASCAR Community & Country Stars Honor Kyle Busch
Kyle Busch was so influential that he touched the lives of those outside of the racing community. Several country music artists paid tribute to him following his death, including Blake Shelton, Gary LeVox of Rascal Flatts, and Dierks Bentley.
Many NASCAR drivers and community members also paused to honor Kyle over the past week. The largest and most emotional tribute came during the Coca-Cola 600 on Sunday (May 24th). Kyle had intended to compete in the race before he died.
Instead, his widow, Samantha, and their two children, 11-year-old Brexton and 4-year-old Lennix, clung to each other as NASCAR CEO Steve O’Donnell spoke, saying:
“Samantha, I want you to know that this sport stands with you, and that you and your children are NASCAR family forever.“
After the Coca-Cola 600, the winning driver, Daniel Suárez, dedicated his victory to Kyle.
