( CNN ) -- An initial investigation shows no sign of foul play in the death of a woman who fell from a roller coaster at Six Flags Over Texas , authorities said Saturday . `` At this point of the investigation , it does not appear there was any foul play or criminality associated with this tragic incident , '' according to a statement released by the Arlington Police Department . Six Flags confirmed that a woman died Friday while riding the Texas Giant roller coaster , but did not provide further details . `` Since the safety of our guests and employees is our number one priority , the ride has been closed pending further investigation , '' the theme park said in a statement . Park medical staff and local paramedics responded immediately to the scene , the park said . Gabe Flores said he was next in line at the amusement park . `` Me and my girlfriend were at the gates and the next ones to get on the ride ... the cars came in and there was a man and a woman in the front , '' he said . `` The man was saying , 'let me out , let me out , my mom fell off . ' `` The man and woman were distraught and speaking in raised tones , said Flores , who lives in Benton , Texas . `` There 's a turn that 's pretty steep , and the person behind her empty seat said she fell out there -- just flew out , '' he said . Flores did not see her fall , but park visitors told CNN affiliate WFAA they did . `` She goes up like this , '' Carmen Brown told the affiliate , raising her hand up in the air . `` Then when it drops to come down , that 's when it released and she just tumbled . '' Brown told the Dallas Morning News that the woman had expressed concern to a park employee that she was not properly secured in her seat . `` He was basically nonchalant , '' Brown said . `` He was , like , 'As long as you heard it click , you 're fine . ' Hers was the only one that went down once , and she did n't feel safe . But they let her still get on the ride . '' Six Flags Over Texas spokeswoman Sharon Parker said the park is committed to determining exactly what happened . `` It would be a disservice to the family to speculate regarding what transpired , '' she said . `` When we have new information to provide , we will do so . '' The Texas Giant was originally designed in 1990 as an all wooden roller coaster . It was redesigned with a steel track and reopened in April 2011 to mark the theme park 's 50th anniversary . At its highest point , the roller coaster is 153 feet and has a drop of 147 feet , according to the theme park . Thousands of kids hurt yearly on amusement rides . Elsewhere , seven people suffered minor injuries in a boat-ride mishap at the Cedar Point amusement park in Sandusky , Ohio , park officials said . The incident occurred Friday evening when a boat rolled backward down a lift hill on the Shoot the Rapids ride , park spokesman Bryan Edwards said in an e-mailed statement . The seven people in the boat were evaluated and treated by Cedar Point emergency medical staff , Edwards said . One of the seven was taken to an area hospital for additional evaluation and was subsequently released , he said . The ride will remain closed until Ohio park officials and inspectors review it .
