Testimony of Charles Arthur Smith at Darren Huenemann's trial
  The Vancouver Sun for October 5, 1990 puts the sun set at 6:43 p.m.  The weather was clear with visibility of 30 miles according to Environment Canada.  This means darkness did not occur until after at least 7:15 p.m.  Mr. Smith may not have known what time it was but he was definite that it was dark.  It is impossible for someone to mistake daylight for darkness.
