Six Flags Roller Coaster Lawsuit: Texas Amusement Park Reopens Ride That Woman Fell Off, Plummeting To Her Death, Same Day Family Sues

Six Flags roller coaster lawsuit: The family of a 52-year-old Dallas woman has filed a lawsuit against Six Flags Over Texas two months after the woman was thrown from the seat of her roller coaster and fell 75 feet to her death right when the amusement park reopens the ride.

The Texas roller coaster lawsuit is taking place because of what allegedly caused the victim, Rosa Esparza, to fall off the 14-story roller coaster that twists and turns at more than 60 miles per hour at the amusement park in Arlington and plummet to her death.

This lawsuit accuses Six Flags of negligence, was filed Tuesday, which was coincidentally the same day the roller coaster known as Texas Giant reopened. The T-shaped lap bar that was supposed to restrain riders didn't work properly, according to the suit. The lawsuit states that inspections done on the roller coasters after Esparza's death "showed that various parts of the security systems on the ride were experiencing inconsistencies and intermittent failures."

Frank Branson, the family's attorney, told ABC News Esparza's daughter heard her mother's screams for help.

"She heard screams behind her. She turned, as I understand it, to see her mother's feet in the air. She turns back to tell her husband and turns around again and her mother was gone," Branson said.

After the incident, Six Flags replaced a "limit switch," an indicator that shows the safety bar is in place, in the car Esparza was riding in because amusement park staff "found the switch to be defective," according to the lawsuit.

Esparza was 5 feet 2 inches tall and weighed more than 200 pounds, which you can ride the ride. The family believes it wasn't properly able to hold in someone of her size.
