This is right across from the Nike campus, isn't it?? I cannot imagine that the streets right there would be quiet or empty at that time in the morning. Bus line 67 runs along 158th, but is not frequent - only hourly. And it's no more than a 10-15 minute walk from the Max line.
Providence St Vincent Medical Center is only a 10-15 minute drive from the apartment. Do we even know she typically drove to work? Pretty sure Providence provides either free or discounted Trimet. I don't know what employee parking is like there.
There's rumbles but nothing official I've seen yet that there are time stamps for doors in the apartment building. From what I can tell, it's a higher end building.
(For those that aren't from around here: in general, this SW Portland metro location is a well-off area - my eldest son and his wife live not far from there. Heck, that's the Costco they frequent, which I'll admit, weirds me out. Especially since son's wife is also a medical professional who leaves for work at a similar bright and early time.)
