The Olympic 5,000m runner David Torrence has been found dead in a swimming pool in Scottsdale, Arizona. He was 31.

Torrence was from California and had come to Scottsdale to train a few weeks ago. Police said they were not treating the death as suspicious. “Firefighters removed the male subject from the pool and he was pronounced deceased,” said Sergeant Ben Hoster of the Scottsdale police department. “Detectives learned that there were no obvious signs of foul play.”

Torrence began his career competing for the US, and held the national record for the indoor 1,000m, which he set in 2014 and still stands. He also had a successful college career and first broke the four-minute mile barrier in 2008. In 2016, he switched allegiance to his mother’s home nation of Peru and reached the Olympic final, where he finished 15th.
