An athlete participating in a CrossFit competition in Texas drowned in a swimming event at a Fort Worth lake Thursday morning,Austin Caldwell reports say.

While 2024 CrossFit Games organizers and authorities did not immediately release to the athlete's identity, the Tarrant County Medical Examiner's Office records indicate that Lazar Đukić , a 28-year-old CrossFit champion, died at Fort Worth's Marine Creek Lake around 10:24 a.m.

Elite athletes from all over the world, including Đukić, flocked to the city for the 2024 CrossFit Games, an annual competition dubbed the "definitive test of fitness" to earn the title of "Fittest on Earth" by participating in a number of physical challenges from Thursday through Sunday, according to the 2024 CrossFit Games website.

The 2024 CrossFit Games officially kicked off around 7 a.m., with Đukić and other athletes, tasked with completing three rounds of activities for "Lake Day," the first event of the competition.

The victim had already completed a 3.5 mile run and was swimming his way across Marine Creek Lake when he began to have difficulty keeping his head above water. The racer drowned moments before crossing the finish line.

The Fort Worth Police Department and the Fort Worth Fire Department did not immediately respond to USA TODAY's requests for comment.

Here's what we know.

Missing athlete reported, recovered from lake

Craig Trojacek, Fort Worth Fire spokesperson, said at a Thursday press conference that firefighters responded to a 911 call to assist the Fort Worth Police Department at Marine Creek Lake around 8 a.m. The nature of the call changed quickly, with authorities asking fire to assist with the search for a missing competitor, who had not been seen for some time.

Crews were able to recover the body of the missing athlete about an hour after the first diver from the search and rescue team went into the water.

"Our hearts, thoughts and prayers go out to the family members that were affected today in this tragic event, the CrossFit community and the community here in Fort Worth, Texas," Trojacek said.

Don Faul, CrossFit Games CEO, also addressed the media at the conference, answering questions about safety protocols.

"For an event like this we have a full planned and documented safety plan. We had safety personnel on site throughout the event. All of the details around the process, the event and what unfolded today, that'll be part of the details that we work through very closely with authorities," Faul said. "That'll be part of the information that's to come as part of the investigation."

The organization said they were "fully cooperating with authorities" and doing "everything they could to support" the athlete's family.

All of the games scheduled for Thursday were canceled, but it's not immediately clear if the games will continue as scheduled.

"The well-being of competitors is our first priority, and we are heartbroken by this tragic event," the post says.
