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. Rosa Esparza was killed July 19 when she fell off the Texas Giant, a 14-story roller coaster that twists and turns at more than 60 miles per hour at the amusement park in Arlington.

The lawsuit, which accuses Six Flags of negligence, was filed on Tuesday, the same day Six Flags announced the roller coaster will reopen this weekend.
