Following the tragic death of a woman who fell from a 14-story roller coaster at Six Flags in Texas, a police investigation has ruled that no foul play was involved in the accident that took place on Friday evening.

Sgt. Christopher Cook said the Arlington police department was preparing a report about the death that likely would be released later on Monday, according to the Wall Street Journal.

Meanwhile, Six Flags said it has also launched its own investigation into the cause of the accident. During the company's second-quarter earnings call Monday, CEO Jim Reid-Anderson said the ride "will remain closed until we are certain it is safe to ride." The park, based in Arlington, Texas, has not seen any immediate effect on attendance.

The victim has been identified as 52-year-old Rosa Ayala-Goana from Dallas who was on the ride alongside her son. Before the ride, called the Texas Giant which is the world's tallest steel-hybrid coaster, witnesses said Esparza said her lap bar was not secure enough before the ride took off, according to CBS news.

According to the report, witnesses say the ride was so fast, they didn't see the woman fall out. When the ride reached the end, multiple witnesses who were next in line to ride the roller coaster heard the son screaming out "My mom, my mom, we've got to get my mom... she's gone." The age of the son was not released and no statement from the family has been given.

The Texas Giant climbs 153 feet before suddenly dropping almost straight down, which is the steepest drop of any wood-and-steel roller coaster. It first opened in 1990 and closed in 2009 for two years to undergo renovations to turn it into a steel-and-wood hybrid roller coaster. It was named best new ride of 2011 by Amusement Today.
