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.
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.
According to this article, Jasmine Parsons said that the woman called saying she wanted to list her house, but then when asked the address, said she didn't know. That would be very peculiar behaviour if it's true.
If someone targeted Lindsay, could they have then made the peculiar call to Jasmine to make people think they were targeting real estate agents in general, to throw investigators off the trail?
