Because Rosay Esparza's death after falling 14 stories from a Texas roller coaster on Friday is being seen as accidental, police and fire officials aren't likely to do a lot of the heavy lifting when it comes to investigating the incident, but will rather leave it to Six Flags Over Texas to conduct its own internal investigation.

The amusement park industry is for the most part self-regulated.

"Quite frankly, Six Flags Over Texas is not required to do anything," a safety inspector told Dallas TV station CBS-11.

Six Flags maintains that it is committed to determining the cause of the accident, but there is no official Texas body that reviews amusement park accidents.
