Katiana Taylor, a 2011 graduate of Vashon High school, died Sunday evening while swimming with friends in Lake Nawatzel in Mason County.

Taylor, 20, who was known to many islanders, had moved off Vashon and was working and living in Seattle. She hoped to attend Washington State University in Pullman this fall, according to her stepfather John Frederickson.

Taylor’s family includes her mother Kaia Frederickson, father Parker Taylor, twin brothers Max and Sam Frederickson, 18, and sister Sasha Reed, 15. She also had many close friends, John Frederickson said.

“Her friends were like family to her,” he added.

When she was younger, Frederickson said, she was athletic and played soccer and softball, among other interests.

“She loved music, loved concerts, loved her friends,” Frederickson said. “She lived life to the fullest.”

According to a news release from the Mason County Sheriff’s Office, Taylor and a group of her friends were having a gathering at Lake Nawatzel on Sunday when someone called 911 to report that Taylor had swum out to a buoy, went under water and did not resurface.

Firefighters and medics searched the waters and located Taylor under nearly 20 feet of water but could not reach her. A member of the Mason County Dive Rescue Team was finally able to reach her, pulled her out of the water and began CPR. By that time, however, Taylor had been underwater for an hour, and she was pronounced dead at the scene.

The incident is under investigation, and an autopsy will be performed this week.

Vashon services for Taylor will be announced soon, according to Frederickson.
