COLLEYVILLE, TX -- Life Time Fitness confirmed today that a man was found dead early this morning in one of its club’s pools.

The body of 41-year-old James Sanchez of North Richland Hills, TX, was found floating in the pool at around 2:30 a.m. at the Life Time Fitness in the Dallas suburb of Colleyville, TX. The club and its indoor lap pool are open 24 hours a day.

The Tarrant County (TX) Medical Examiner determined Sanchez died of coronary atherosclerosis—a medical condition responsible for most heart disease—with an accidental drowning.

“Our thoughts and prayers are with the individual’s family, as well as with our team in Colleyville,” Life Time said in a statement.
