Yount and another student decided to jump from the 26-foot-tall San Telmo bridge for fun at about 3:30 a.m., according to the Spanish newspaper Diario Desevilla. A third student decided not to jump, according to the paper.
A witness called police after one of the jumpers came up with signs of hypothermia and Yount did not resurface, according to Diario Desevilla. The water temperature was about 44 degrees.
The police searched the Guadalquivir River with flashlights, the paper said, and firefighters and divers were called in.
Yount's body was found hours later, at about 8:40 a.m. Nov. 20. He was pronounced dead at the scene.
The 2011 Foothill graduate was a member of the Cal Poly golf team, where he helped lead his squad to a third-place state finish at Poppy Hills Golf Club in Pebble Beach, according to a posting on the school's sports site. He was due to return to the school in January.
Yount attended St. Raymond's Catholic School in Dublin through eighth grade before attending Foothill. He was a junior at Cal Poly at the time of his death.
Diario Desevilla says police are continuing to investigate the death, although there appeared to be no sign of violence. It's unknown whether Yount drowned or struck one of the bridge's pillars.
Yount is survived by his parents, Greg and Sandy Yount, and his brother, Adam.
A memorial service has been set for 10 a.m. Saturday, Nov. 30 at St. Raymond Church, 11555 Shannon Ave., Dublin.
