I switched off Google location services at much inconvenience to myself when I realised it had mapped my location for the previous however many years.
And then I discovered, thanks to an Associated Press investigation, that Android and iPhones store your location data even if you've switched the privacy setting to prevent them from doing so.
That investigation was 2018 and the Putney incident was 2017, so, if he had his phone with him, there’s a chance that his Google/iPhone settings will still have a record even at this distance.
