ARLINGTON, Texas -- Authorities have identified the woman who fell to her death from a roller coaster at a North Texas amusement park as a 52-year-old Dallas resident.

The Tarrant County medical examiner's office said Monday that Rosa Ayala-Goana suffered "multiple traumatic injuries" when she fell Friday from the Texas Giant roller coaster at Six Flags Over Texas. The amusement park is in Arlington, just west Dallas.

Witnesses told authorities that Ayala-Goana expressed concern moments before the 14-story ride began that the safety bar had not completely engaged.

A Texas Department of Insurance spokesman said Sunday that Six Flags was in compliance with state regulations requiring amusement ride operators to have $1 million liability insurance on each ride, and provide proof of an annual safety inspection by a certified engineer.
