Is it a clue?

I've been trying to verify this tip with limited success so I'm putting it out there to see if anyone knows more. This one comes from a source close to the crime scene.

Word is police were once interested in a pair of brothers who made snow out at Loon Mountain in Feb. 2004. They drove to work every evening along Rt. 112 and would have passed the scene of Maura's disappearance. My source was told by police that the night Maura disappeared, the brothers did not show up for work.

If you know who these brothers were, please email the info to me so I can attempt to rule in/rule out this pair.
