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.

Dave Shapiro, Sound Talent Group's co-founder and a heavy rock music agent, died in a San Diego plane crash on Thursday morning at age 42.
