Lawsuits Allege Six Flags X2 Caused Over 100 Brain Injuries

When the X2 roller coaster returned to the station at Six Flags Magic Mountain on July 5, 2026, Camille Marquez looked over at her mother. Pamela Guillen sat with a vacant stare and her mouth open. Camille thought at first that she was joking. She quickly realized something was wrong.

Guillen, 39, had come to the Valencia park that day with her family for Camille’s sixteenth birthday. After the ride she was confused and unstable on her feet. She collapsed and was taken to the hospital. Surgeons performed emergency brain surgery to stop the bleeding, removed part of her skull, and intubated her. She was in a coma. She did not regain consciousness for two weeks and spent nearly a month in the hospital.

“I was confused and disoriented, and I remember seeing the fear in my daughter’s eyes and how scared she was. Everything went blank. My next memory is waking up in the hospital about two weeks later,” Guillen said. “I had suffered a traumatic brain injury and needed emergency brain surgery to stop the bleeding and had to be intubated. I was in a coma. I spent almost a month at the hospital.”

Six days later, on July 11, 25-year-old Naomi Greer-Wilkinson rode X2 with her siblings and friends. Shortly after exiting she collapsed. She was taken to the hospital with massive brain bleeding, underwent multiple operations, and remains in a vegetative state, unable to speak or move and dependent on a ventilator. Her family filed suit on her behalf.

“Naomi had no idea, when she was going to Magic Mountain with her siblings and her friends, that she was signing up for something that could potentially rip the veins in her skull, cause catastrophic bleeding, and lead to a coma,” attorney Christopher Bulone said.

Months earlier, on February 7, Michael Wilk had ridden the same coaster with his daughter and grandchildren. The lawsuit states that Michael’s head began slamming violently against the headrest of his seat. Immediately upon exiting he felt stabbing pain in his head, dizziness, and difficulty walking. In the weeks that followed his cognitive function declined. An MRI later showed massive brain bleeding and swelling. He underwent two surgeries to relieve the pressure. Wilk, an insurance defense attorney, can no longer practice law. He continues to suffer debilitating headaches, confusion, dizziness, memory loss, and personality changes.
