Fred Murray releases odd statement regarding Creep's videos.

This is coming from MyFox Boston 25. You can watch the segment they did on the Creep's videos by following the link.
According to MyFox Boston 25, the Murrays released this statement today:

"The family is deeply saddened to learn and view that a seemingly clinically disturbed individual would post misleading and cruel videos online… the family respectfully requests the public to ignore and disregard this hideous information and allow investigators to pursue leads of substance and credibility."

Yet again, Fred's reaction makes no sense to me. If I was Maura's father, I wouldn't rule any lead out until it was followed through. If I didn't know what happened to Maura that night, I would be interested in any new info, especially as something as bizarre and threatening as this.
Everything about this case is just strange.
