Investigators say a plane crash in San Diego that killed six people happened as the private plane approached an airport whose runway lights were out in heavy fog.

Friends paid tribute to Daniel Williams, a former drummer for the metalcore band The Devil Wears Prada, and Dave Shapiro, a music agent who worked with Sum 41, Hanson and other bands.

NBC 7 is learning much more about the six people who lost their lives aboard the small plane that crashed into San Diego’s Murphy Canyon neighborhood.
