March 16, 1997 ˜ February 21, 2019

SGT Seth Nathaniel Witherup, 21, passed away on February 21, 2019, on Marine Corps Air Station Iwakuni, Japan. Seth was born March 16, 1997, to Imelda Ortiz and Ron Witherup in Corpus Christi, TX. The family moved to the Pacific Northwest in 1999 and in 2015, Seth graduated from Prairie High School.
Seth is survived by his mother, Imelda; his father, Ron; his sister, Clarisa; and his brother, Sean; as well as many grandparents, aunts, uncles, and cousins.
Seth experienced life to the fullest. He loved his family deeply, cherished his home in the Pacific Northwest, and always dove head first into new experiences. Seth was quick to laugh, and driven to help and serve others, be it a stranger on the street, his friends, or his country. Seth’s trademark smile was known around the world and embodies the friend, brother, and son we will all miss very, very much.
