My apologies if this has already been discussed, but the mobile phone that was charging could have been intended to be used to locate the drone by satellite GPS with no mobile coverage needed. If he had the Mavic app and had registered his drone, which he probably did, the police should be able to get access to the data through Mavic and check if and where the drone was flown and may have crashed. Maybe they located the downed drone and tried to hike out to collect it using one phone, while the other phone charged. The tent and contents were thoroughly burned, not just a tent catching fire, everything completely and utterly destroyed by a hot, fast fire which left the car only singed. A hiker walked past at 2pm the day after he had made radio contact and police said the tent had burned and they disappeared some time between the radio contact and the hiker seeing the burned tent, so pretty much the first night/or the day after they set up camp was when they disappeared. Did a fire investigation forensic team check out the burnt tent to properly investigate the cause? So far it seems it is all speculation. Have police tried to track where the drone went - if it was registered the data is probs. still sitting there? Did police check tyre tracks at and around the site before contaminating the scene? Did they fingerprint anything? Russell had the car keys with him and a spare set was found hidden at the car. This makes me think they radioed in the previous afternoon, set up camp in a private spot away from the main camp area. Tried out the drone, lost it. Put the phone on to charge to use to track the drone. Left the car locked and walked off to start searching for the drone and way overestimated their ability to manage in the terrain, got lost or he had a medical incident and she had no idea where she was or what do do. Her not at all familiar with the bush etc. him elderly with a heart condition.
Police say drone could hold vital clues about disappearance of elderly campers
