Karen Louise "Lancaster" Duncan

Karen Louise Duncan, age 65, of Caldwell, Idaho, passed away on August 3, 2025, peacefully of natural causes, surrounded by her loved ones. Karen was born in Long Beach, CA to Louise Santassusso and Dale W. Lancaster. She was raised in and around Ontario and Nyssa, OR as well as Parma, Idaho with her father Dale and his wife Karen's mom Susan K. Lancaster.

Karen had 4 children: Kimmie Jo in '78, Misty Lee in '81, Jonathan E in '85 and Chelsi Kay in '93 whom she loved dearly. Karen was all about her kids and family. She was known for her bravery, grit and of course her sass, but most of all for the love she showed those around her. Karen met the love of her life James Scott Duncan in 1992 while seeking a new adventure driving truck (18-wheeler). Scott and Karen married July 16, 1994, in Caldwell. Karen loved making crafts, scrapbooking, and making holiday wreaths. She loved shooting darts – she even got all three of her daughters to shoot with her on leagues throughout the years. She met some good friends while playing darts. Karen loved camping, picnics, BBQs, and traveling. Most of all, spending time with family and friends. Karen was a devoted mother to her four children, grandmother to her grandkids and great-grandkids, who poured her heart into her family.
