Well...we know the Collins family is happy with how the investigation was going under Smock's authority. They have mentioned it on more than one occasion.

And as far as Lyric's "side" of the family goes, well...they made it clear from the get go that LE was wrongly focusing on them and their past behaviors. They were screaming that it was an abduction from day one. While they were dragging the lake and bringing in dogs, etc they were wanting it to be classified as an abduction, not missing or drowned kids. That was a whole week before they officially labeled it an abduction. They told of cops/investigators beating down doors in the middle of the night, multiple polygraph tests, flat out accusing Dan of being involved, etc...but still kept their faces out there begging for help.
Misty posted a plea on the FB page of John Walsh (or was it Mark Klaas? I don't remember for certain) when she asked what else she could do. It was a begging plea - saying they needed help and she was "on the verge of losing it" or something of the sort. Helpless is how she explained her feelings.
Then, once the girls bodies were found they went completely private. They did a ceremony for Lyric, no media circus, no "open to the public" service, nothing of the sort . They grieved in private and to my knowledge haven't said one way or the other about how they feel the investigation is/was going after their bodies were found.
Maybe they feel that it honestly doesn't matter how the investigation is going - Lyric isn't coming back one way or the other, so finding or not finding out doesn't change the outcome. I don't know - they are both in jail and the media doesn't seem to ask or care how they are doing. All interviews and media have been with the Collins since their bodies were found.
