Local people say that at the time of the crash, 9pm last night, fog had closed in on the area and visibility was poor.

On its own that doesnt mean a lot.
Naturally an experienced pilot who knows his local area is going to safely make approaches in conditions considered poor by lesser experienced pilots.
Did the aircraft collide with terrain in controlled flight? Did it stall in poor vis?
You cannot make presumptions on innacurate weather reports made by local people. All they do is indicate that the weather may not have been CAVOK
