A 16-year-old Bothell boy was killed on Interstate 405 in Kirkland Saturday morning.

Lukas Defiesta’s body was found near exit 22, which leads to the Northeast 160th Street bridge overpass between the Evergreen Hill and north Juanita neighborhoods.

“They’re looking at it as he either jumped or fell,” said Washington State Patrol Trooper Chris Webb. “But the disturbing part of that incident was the subject, when laying on the roadway, was struck several times by different cars.”

Webb said one person stopped at the scene and another called state patrol to let them know they had hit the boy but he estimates there was probably more than two vehicles that hit the teen.

Defiesta’s cause of death was from blunt force injuries of the head, trunk and extremities, according to the King County Medical Examiner’s Office.

The freeway was closed for a few hours Saturday morning during the investigation, which is still ongoing.

Washington State Patrol detectives are seeking witnesses to Defiesta’s death.

Anyone who may have observed the victim, who was wearing pants, tennis shoes, a black sweatshirt with large headphones or believe they may have struck an object in the area around 4:40 a.m. on Saturday are urged to call Sergeant Detective Stacey Moate, (425) 401-7745, or Detective Greg Wilcoxson at (425) 401-7746.

Friends and family members placed roses, notes to Defiesta, photos and other items that reminded them of the teen on the Northeast 160th Street freeway overpass. Tea lights were lined along the south side of the bridge, as if there was a recent memorial.

“… It will never be the same without you. You never failed to put a smile on everyone’s face. God gained a new angel. Rest in paradise Lukas, I’ll see you eventually,” said a letter signed “your drunk best friend.”

Other letters and notes said Defiesta was his friend’s “anchor” and helped his friend through many “rocky situations.” Another said, “Defiesta, I love you man. Remember to pre-game and post-game in heaven.”

And others commended him for his kindness, support, understanding and love.
