Jessie Grace was 23 when she disappeared on June 20, 2016, and there have been no confirmed sightings of the young woman. Her mother, Sherrie, says she’s on a mission to find her and even had to infiltrate gangs to learn information, because she claims the Wenatchee, Washington police force are corrupt and botched the investigation.
