31-year-old Amanda Lennick has been missing since Saturday. She had recently purchased a home in the area where the slide occurred, and she was inside when it hit.
KEPR spoke to Amanda's mother, Jamie Lennick, who said her family was devastated by the news. She did not want to give a formal interview.
The Seattle Times reports three men were at Lennick's house installing a water heater and a satellite dish when the mudslide hit. William Welsh, Stephen Neal and Steven Hadaway have also been reported missing.
Amanda was a graduate of Kennewick High School and had a bachelor's degree from Washington State University.
UPDATE: Amanda Lennick's mom tells KEPR Lennick's body has been recovered and officially identified.

Our hope is for all victims to be found and rejoined with their loved ones"
