Searchers are back out at the Sioux Falls, South Dakota, landfill today to look for evidence in the case of a missing deaf woman, formerly from Iowa. Sioux Falls police say they found body parts believed to be those of Darlene VanderGiesen on Saturday, but didn’t find anything during a search yesterday.

Daphne Wright has been arrested on a first-degree murder charge and was expected to make a court appearance today. Both women are 42 years old, from Sioux Falls, and knew each other.

Vander Giesen, formerly of Rock Valley, Iowa, has been missing since February first. According to court papers, fragments of human tissue and bone that matched VanderGiesen’s D-N-A were found in Wright’s basement.
