A Kirkland man rescued from Lake Washington Monday by a stranger died at Evergreen Hospital.

Tyrone Fabroa, 35, was out paddleboarding with his 19-year-old brother when he lost track of the paddleboard and went under the water.

Peter and Jill Robertson were enjoying the afternoon from their Kirkland condo when they noticed something was wrong out on the waters of Lake Washington around 11:30 a.m. Monday.

“There were two brothers out there and one was trying to bring a paddleboard back to the other when he went under the water,” said Peter Robertson, who used to train lifeguards for a living. “I saw him going up and down in the water and that is never good.”

The couple lives in the Sunset Condominiums along Lake Street near David Brink Park.

The two waited just a moment before Jill turned to her husband.

“I told him ‘You can help him, you have swam all your life,’” said Jill.

Peter Robertson ran out of the condo, grabbed a life preserver and leaped into the water. Another man followed Robertson into the water with snorkeling goggles and flippers. But when the two got to the location, about 50 yards from the dock, Robertson became aware Fabroa, a Kirkland resident, had gone under the water.

“He went to the bottom,” said Robertson. “We did a grid pattern to try and find him.”

Robertson and the other man were finally able to locate Fabroa and bring him to the surface. The man was not breathing so the pair put him on the paddleboard, opened his airways and got him to the shore.

The King County Sherrif’s marine patrol was on site by the time the three reached shore and began CPR immediately.

“Hopefully we gave him a fighting chance,” said Peter.

The two men did give Fabroa a fighting chance as he was taken to Evergreen Hospital alive but in critical condition but died later Monday night.

“Since we have not had great weather I think people have a false sense of security,” said Robertson, noting that he did not see any flotation devices beyond the paddleboards. “But if you look out there you can see whitecaps.”

Kirkland Police Department spokesman Allan O’Neill said that the man was wearing a fanny pack life vest but it was unclear if it was deployed correctly.

Peterson also said he thought the first four to six feet of the water was about 68 degrees: “But when you get down further it gets a lot more chilly.”
