Impact damage looks to me like the pilot was not in control at the time
The aircraft seemed reasonably intact. So it looks like a CFIT to me.
4/8 cloud seems the question as to whether it was a NVFR flight and LSALT seems to be the question whether it was an IFR flight or either.
One should consider all factors and ignore media speculation in cases such as this. The ABC this morning stated Angel Flight "chartered" the aircraft from the pilot???? Oh, (and weather could be a factor). Nobody mentioned "ageing aircraft" or the fact that it had no ballistic parachute or an on board entertainment system. It probably just disappeared from radar screens as is normal, or the pilot had no flight plan, or it wasn't a mercy flight because he was coming away from medical help.
God preserve the souls of the dead and insulate them and their loved ones from the repercussions that are bound to follow.
You may all like to reflect and offer a silent prayer for all the times you have got away with similar.
