In June, 2012, Samantha Weaver, 27, and a mother of two, disappeared near Shawnee.

Almost three years later, agents from the Oklahoma State Bureau of Investigation gathered in a shed on Rustic Oaks Drive outside of Shawnee to search for her body using a new device.

It is called FINDAR, a tool with ground-penetrating radar capable of finding secret graves.

Graves of homicide victims often remain hidden for years, but with the help of the new tool, more bodies should be recovered quicker, Special Agent Francia Thompson said.
