They can’t be too far out of the area of the cemetery where they believed they would find them. It’s only 25 minutes from the parking lot. This would suggest whoever may have killed them could have lived in the area so that would indicate the bodies of these two women could be somewhere around the vicinity of Lewisville lake since Ritter cemetary is at the southern tip of it. What do we know about Kevin and where he lived / worked, hung out etc?
