Absolutely SA and Shadow. Disposing of a phone with the body is risky. Travelling with the body and the phone is bonkers. Ristevski & Bayley probably wouldn’t have realised the risk of travelling with an intact phone.
Stephenson though would know better.
He made errors with the phone which I can only put down to panic, an inability to think clearly, and haste. Why was the phone not completely smashed & destroyed in Canadian, rather than carried away and discarded in its intact wallet in water where it would survive? Stephenson would know better than to not completely decimate that phone. I don’t believe that anyone else was involved so I’m thinking he was panicked, weary & rushing.
Mick Murphy said that Sam’s phone went to voicemail when he called her that morning. Probably intentionally turned off.
Sam’s phone pings at 5pm. Probably accidentally triggered.
Sam’s phone gets chucked in a dam beside the road on a route that leads to repeated search sites. Probably a panicked throw before or after dealing with the body.
Sam was reported to be wearing a smartwatch too. He would know to lose that too, but as the phone disposal appears not well thought out, the fate of the watch was probably spontaneous too. These tech pieces might be the arrows pointing to routes and broad search sites.
Q: How do you destroy a phone (or watch) in Canadian without leaving evidence, and how do you remove a phone (or watch) from Canadian without it betraying you and your journey?
The phone , at first glance, seems like an anomaly., doesn't it, R... .. out of sync with the rest of the events... all the previous actions seem to have gone off without a hitch, the encounter , the murder, the disposal of the body,.. yet the phone.. Just laying around by a slowly shrinking dam.. Still with all the info intact including various cards, etc.. An anomaly.
I thought, it might have been that he gave the phone to someone, as a gift, as a placating issue, for being late , or missing a deadline... something like that, and this giftee suddenly realised the significance of the phone, and hurled it away at the first opportunity, where ever they were at the time... that maybe it wasn't the killer who tossed the phone. But , you know. even killers get a bit discombobulated,... he had no way of knowing what measure of time he had... even he must have been a bit surprised that the hue and cry for Samantha would erupt into a full bore search so quickly ... as it turned out he had approx . 4.5 hours, all up to get things sorted.. eg. murder at 8am , Samantha reported missing at 123.0 - 1pm....
From that point on, people were observant, and alert... roads would be watched, neighbors checked up on.. he did not have much time, really , broad daylight, Sunday traffic ...
Also, he was a technician. electrical.. surely he would know to dismantle the phone before chucking it.. unless he was well and truly rattled, by then.. that he suddenly realised , late in the day (5pm ping ) that he had her phone still with him..
We only have to wait until September..
