We know investigators used a technology called ground penetrating radar - or GPR - as they searched a home on Page Boulevard in Springfield two weeks ago.
Eventually, they discovered three bodies.
The model we got a look at is a little bit older than the one used on Page Boulevard, but we're told it's very similar.
This gives us an inside look at that investigation.
As police searched 1333 Page Boulevard, eventually discovering three bodies on the property, they used a technology called ground penetrating radar, or GPR.
"Wherever there's a change in density or primarily water content or soil content, then you'll get kind of a reflection back," said Doria Kutrubes, the founder and owner of Radar Solutions International.
Kutrubes gave Western Mass News an exclusive look at the technology used on Page Boulevard.
"It's up to us to take a look at these ink blot type of reflections and put it together in a map to try to figure out the horizontal and lateral extent and the depth of things," Kutrubes noted.
These electromagnetic waves are the same waves you use in a cell phone, but actually less power than a cell phone.
This complicated work, Kutrubes said, is oftentimes done pro-bono.
"This is, in part, because we're trying to give back to society," Kutrubes added.
Radar Solutions is just one company that does this kind of volunteer work.
Kutrubes said that she has done extensive work with the Molly Bish Foundation and Mission for the Missing.
The investigation into the deaths of the three women found at the home on Page Boulevard continues and no charges have yet been filed.
