I think you should read the article again.
> "Under Mysterious Circumstances" - means to me the investigators are: wtf.
They will have a very good assessment of the situation. They are not "wtf"
They were/are missing something from their normal patterns. They had to react to protocol on the day. Now they will want something solid.
They will know how heat exhaustion looks, they will see all water bottles are empty for instance. It also is/isn't normal for that to happen within 2 miles of the car. Deputies also would not call them experienced hikers if they ran out of water. Nor would you expect people with their world travel and older age to hike with a baby with too little water. The police know a lot more than what we know and I'd find it unlikely from here the outcome will be different to what the police suspect.
