You might try email or even snail mail. Did they at least give you the name of the lead detective if it is an open case and/or did they say if they have a Cold Case Division?
Are you her oldest child? Who handled the affairs of her death when she passed? What I am getting at here is if you are naturally now the lead representative for your family. LE would rather deal with just one person v. multiple family members, IMO.
Another thing, I think WS likes to vett the family members posting so nobody can hijack their nic and post as if they are them etc... You need to PM a mod, I think. Let me find the right link for that...brb
