Update March 18 15:00 EST
Owner of N26DK Wes Caves of Digicut Systems was piloting his own aircraft when it crashed, sitting in co-pilot's seat and also killed - long time friend John Davis who was not type rated but owned a twin engine prop aircraft.
2 other passengers 1 listed as serious, 1 fair, and a lady from the 2nd home hit listed as fair.
Seems nobody else was killed or transported to hospital. Earlier reports stated 2 persons on the ground were killed.
Local news also reported that the aircraft did touch down before it aborted and went around ???, however NTSB should take 7 - 10 days for preliminary report.
