I'm curious what information LE has access to that has enabled them to narrow the span of time here. A three-hour window in the dead of the night, IMO, makes it less likely that either of the victims were awake and therefore more probable that they were helplessly vulnerable to the attack. I do realize that ST could have been awake at that hour given that he seemed to have a lengthy commute to the dental practice.
Possible evidentiary information I can think of:
Cell phone data
Video footage
Alarm auto-data (such as a door opening/closing)
Time of death (not yet announced, as far as I'm aware)
Apple/smart watch data (if either of the Tepes wore them)
Can anybody else add to this list?
JMO, but for me, this case serves as a reminder that, just as we don't know who among us are the predators, neither do we know which of us can become the prey, nor when or where. Sometimes life feels like a lottery.
