Three 18-year-olds were taken into custody after a woman was fatally shot, and a man was injured outside an indoor theme park in North Richland Hills overnight, police said. 

The North Richland Hills Police Department said that just after midnight Sunday, officers were called to a shooting outside Malibu Jack's, located in the 8600 block of Airport Freeway. When they arrived, two victims were found. 

Police said a woman, identified as 21-year-old DaShayla Jones, was pronounced dead at the scene, and a 23-year-old man, whose name has not been released, was transported to a hospital. The man is expected to survive his injuries. 

Investigators learned there was a fight between several people before the shooting happened, according to a news release. The police department said two of its officers were working off duty and responded when the shooting erupted. One officer was able to return fire as the other officer applied a tourniquet to the male victim's injuries before medics arrived. 

Police said three 18-year-olds were taken into custody in connection with the incident; however, late Sunday morning, they said after speaking with witnesses, two of them were not involved in Jones' murder. Police said those two are still in custody on unrelated class C charges that "were placed at the time of the arrest." 

The third 18-year-old arrested in connection with the murder is from Fort Worth and is expected to appear before a judge on Monday, Sept. 8. 

Malibu Jack's North Richland Hills location posted on social media that it would be closed on Sunday.

The investigation is ongoing.
