I did some more reading. It turns out that the day after Lindsay was killed, another young female realtor there got a strange phone call from a woman with a "heavy foreign accent ".The woman said that she wanted to buy a house in the million dollar range. The young realtor, Jasmine Parsons, had oreviously dated.... Jason Zailo, Lindsay's boyfriend.
Jason Zailo hired a well known criminal lawyer. LE had Jason and his lawyer go over to the house to do a reinactment of the evening when Jason found Lindsay's body. LE searched the gutters of the house....
What if the couple didn't speak english as a firat language, and didn't watch local news ? And so they didn't know about the murder ? And they left the country soon after ? What if they really did want to buy a house, and hence the call to Jasmine Parsons ? In such a small group of young real estate people,it could have been a coincidence that Jason had dated Jasmine.
My other theory won't hold water ; LE won't say if the potential buyers asked specifically to look at that house,or if Lindsay selected that house to show them...
Okay, yes, it could well have been someone Lindsay knew.....
