Just reading this article now.
A neighbour across the street had messaged Lesley at 11:31pm to see how her moving arrangements were going and how she was. Lesley responded at 12:03am that it was hectic and stressful, but in a couple of weeks it will all be over, and that she would see him soon.
He also sent an email the next morning at 9:45am to a group of residents (who were trying to stop the car dealer parking cars in the back) to tell them Lesley was leaving the group as she was moving, and wishing her well. She didn't reply to that email.
The rubbish truck picked up the rubbish with Lesley at 10:31am. (Guessing that is the camera time)
The neighbour thinks it was Lesley's brother or one of her friends who suggested she move into the retirement village.
The purchase of the retirement unit was dependent on the sale of her apartment.
Nothing in the article to say where the police are getting their special interest in the 4am-5am (IIRC) time period.
