I get the impression that little Deorr's mom is rather an introvert, more the quiet shy type, may be not very comfortable in front of people. I can understand that as I'm the same way. She also looked quite depressed in that last interview, I don't think she's functioning well at all, JMO. That may be one explanation why they aren't more in the public eye.
No, this family is not very vocal, certainly nothing like Beth Holloway who didn't hesitate to get out and make a lot of noise and constantly kept Natalie's case in the headlines. And she had a lot of blame and criticism leveled against her as well, that she allowed her 18 y/o daughter to go to Aruba where alcohol was legal and with very few chaperons. All against Mr. Holloway's wishes, a very wise man, IMO.
I guess my point is that how they are dealing with this in the public eye doesn't mean they are guilty of anything and don't want their son to be found as much as any parent would. They are who they are, that's all. Not to mention all of the cruel baseless accusations and criticisms being thrown around on SM which certainly haven't helped. I don't know what happened to little Deorr, but I want to give the parents the benefit of the doubt unless or until I see evidence and reason not to do so. JMO
