MILWAUKEE (WTAQ) - An autopsy is scheduled Tuesday on a UW-Milwaukee student who died Monday in a campus swimming pool.

The medical examiner’s office said 19-year-old Connor Driscoll of Madison was practicing for an aquatics test for the U.S. Air Force in advance of an entrance exam.

Authorities said he swam underwater for 25 yards, did some flips and somersaults, came up for air, and then immediately sank.

Lifeguards jumped in immediately, pulled Driscoll out, and tried CPR. Rescuers from the Milwaukee Fire Department also tried to revive Driscoll with a defibrillator.

He came to the pool with a roommate, and he was swimming at the time Driscoll went under. UWM spokesman Tom Luljak said the initial thought was that the victim suffered a health condition.

A doctor diagnosed him with sleep and bleeding disorders in 2007, but a heart test in 2010 showed nothing unusual.

The roommate told authorities Driscoll fell and hurt his face a few weeks ago while carrying another person on his back – and he did not seek medical help at the time.

Driscoll was a sophomore in the UW-Milwaukee College of Letters and Science. He had not declared a major.
