During February 2009, contractor hired by JPAC traveled to the crash site to confirm the location. During that same year, a local resident turned over additional bone fragments he had taken from the crash site previously.

On November 18, 2016 the DoD announced the identification of Langhorst based on circumstantial evidence and a mDNA analysis that matched his nephew.
