Gurnee Police said a 17-year-old boy from Aurora, Illinois, suffered a thigh wound and a 19-year-old woman from Appleton, Wisconsin, suffered a leg wound.

The third victim suffered a shoulder injury but declined transport to the hospital, police said.

"Based on the initial investigation, a white sedan entered the Six Flags parking lot and drove toward the front entrance of the theme park," Gurnee Police said in a statement. "The suspects exited the vehicle and began shooting toward another individual in the parking lot. The suspects got back in the white sedan and quickly left the area."

"The shooting this evening was not a random act and appeared to be a targeted incident that occurred outside the park," police said. "This was not an active shooter incident inside the park."

Park officials told the Associated Press that the park was closed early Sunday but reopened as scheduled Monday morning.

The names of the victims and details about the suspects were not immediately released, the news outlet reported.

Six Flags has announced plans for reopening its theme and water parks in 2021.

In a press release, the amusement park giant is celebrating its 60th anniversary, so the company said they would welcome guests back while following safety measures in California, Illinois, Massachusetts, Mexico City, and Canada.

The company said the reopening dates of all 26 of its parks would be based on local, state, and federal COVID-19 guidelines.

In a statement, Six Flags Vice President of Park Operations Bonnie Weber said the parks last year safely entertained millions of guests at 21 of their 26 parks.

"We kept our guests and team members safe by requiring masks to be worn in the parks, providing contactless temperature and security screenings, enhancing our cleaning and sanitization measures, and closely monitoring attendance throughout operating hours in order to maintain proper social distancing," Weber said.

The company also announced they plan to hire thousands as they gear to reopen.

Around 65 people were sickened Saturday afternoon at a Houston-area water park in what local officials called a chemical incident.

"In the area around the kiddie pool in this water park, a lifeguard was sick, and soon after that, more and more people began becoming sick," Harris County Judge Lina Hildalgo said in a news conference outside Six Flags Hurricane Harbor Splashtown in Spring, Texas.

"What began as a fun family day has turned into very much a nightmare for many families," she said.

Public health officials are ordering the park to remain closed until they determine exactly what happened.

"The chemical combination was about 30-35% sulfuric acid and 10-13% bleach, and that's all we have at this time," said Spring Fire Department Chief Scott Seifert.

Hidalgo said all equipment readings during the incident and samples taken immediately afterward showed conditions within normal legal limits, but added that actually makes her more concerned. "Their current procedures very clearly cannot adequately ensure health and safety," she said.

Most patients had what Seifert described as "respiratory distress."

Ladder truck used to decontaminate those affected

A 3-year-old girl was the "most serious case" and was taken to Texas Children's Hospital but is now stable, according to Hidalgo. Another victim was a pregnant woman who was believed to be in labor as she was transported from the park, said Hidalgo.

"If you were at the water park, if you are feeling sick, please make sure you seek medical attention. If you feel sick, call 911. If you find yourself in the emergency room, please, as soon as you walk in, let them know that you were here. Do not sit in the waiting room with other folks because we don't know yet exactly what chemical, what caused these illnesses. And so we don't want to expose other folks to that," she said.

Chief Seifert said 26 people were taken to area hospitals and 39 refused transport. He said they were decontaminated before leaving the park.

"What we do is we set up our ladder truck that has a nozzle on the end, we point it straight down about 15 feet above where the people will walk through, and they walk through there and they basically massage their eyes and things like that to get any chemicals out of their eyes if they're affected. And then, after a period of time, they'll walk through it and walk out," Seifert told reporters.

The park was last inspected June 29, according to Harris County Fire Marshal Laurie Christensen, with nothing problematic found at the time.

"The safety of our guests and team member is always our highest priority and the park was immediately cleared as we try to determine a cause," park spokesperson Rosie Shepard said in a statement to CNN affiliate KPRC Saturday evening.
