I agree that the media would have been all over a search of the communal house, if they had known about it. But, IIRC, the FBI showed up at Megan's on Oct 8th. LE never leaked a thing. We knew nothing about this 8:30 pm call until Megan was interviewed by media weeks later. So, imo, whilst the press was parked outside the home where the parents were staying, waiting to possibly snap Debbi on a smoke break or the kids getting a breath of fresh air, the FBI likely did a thorough voluntary search of the communal house to make sure Lisa was not there. I'm thinking Megan was freaked the eff out when the FBI showed up at the door and agreed to whatever they requested. Meanwhile, the press was clueless about the real story that was going down mere miles away. JMO...
