NEW YORK — Six Flags shares are down slightly as the company continues to investigate a fatality at one of its parks.

A woman died Friday while riding the Texas Giant roller coaster at the company's park in Arlington, Texas. The 14-story ride, which remains closed, is touted as the tallest steel-hybrid roller coaster in the world.

Six Flags CEO James Reid-Anderson says the company won't release any further information until its investigation is complete.

Six Flags also said Monday that its second-quarter net income dropped 34 percent, pulled down by a steep increase in income tax expense and lower park attendance stemming from bad weather. Its results fell short of Wall Street predictions.

In midday trading, shares of Grand Prairie, Texas-based Six Flags Entertainment Corp. are down 42 cents to $35.43.
