LAKE COUNTY, Calif. – Seth Weston Costner chose to leave this world on Friday, June 12, 2015.

He was 18 years old.

He was born on Sept. 29, 1996, to Frank and Mary Costner. Seth had a strong faith in Jesus Christ, our Lord.

He loved reading, video games, Star Wars, and Legos, and he had a fantastic, dry sense of humor. His favorite authors were Tolkien, Ted Dekker and Robert Jordan.

He loved the outdoors, shooting with his brothers, and being with family. He grew up in a big, growing family. It was Seth’s dream to live and homestead on the Costner homestead just south of the Oregon border, which has been in the family for five generations.

Seth leaves behind many loving family members and friends, including his wife, Haeli; parents, Frank Costner, and Bob and Mary Henderson; siblings, Lanen, Brandon, Brandon Tyler, Justin, Elly Marie, Abby Dawn and Ally Rose; as well as foster siblings; grandparents; aunts; uncles; cousins; nieces and nephews; and many others.

The love and joy our sweet, gentle Seth brought to our lives will be with us always. We will always love and miss him.

A memorial service was held at Grace Church in Kelseyville on Monday, June 15, to help friends and family honor Seth’s life.

Arrangements under the care of Jones & Lewis Clear Lake Memorial Chapel.
