They went missing somewhere between Portland and Gold Beach, after brunch on Saturday.
OK, the last call from their cell phone was at 2 PM on Saturday.
However, the Gold Beach hotel heard from them at 5:45 PM, which means they (or someone) called from a different phone.
We don't know where they were at 2PM, but the police do. (Like had they left Portland, and if so, how far from there were they and was it on the way to Gold Beach?)
And we don't know where they called the hotel from almost 4 hours later or why they thought they'd be so late arriving (or if it was even them calling). I wonder if their Portland friend knows which boutique they were going to visit there after leaving him, and whether police have contacted that shop to see if the Kims made it there.
Also wonder if there's any chance the hotel recorded the call at 5:45 PM.
