Drummer and Music Agent Among 6 Killed in San Diego Plane Crash

They were two rock music veterans who were excited to fly together from New Jersey to San Diego.

One was Daniel Williams, a former drummer for the metalcore band The Devil Wears Prada. The other was Dave Shapiro, a music agent who worked with Sum 41, Hanson, Jefferson Starship and other artists, and was also a pilot who ran his own aviation business.

In an Instagram story posted on Wednesday night, Mr. Williams shared a photo of their plane, a Cessna Citation, on a tarmac and two more photos of himself in the co-pilot’s seat.

“Here we goooooo,” he wrote.

But after crossing the country, the jet hit power lines and crashed in a residential neighborhood as it prepared to land in dense fog in San Diego early on Thursday morning.

All six people aboard were killed, eight people on the ground were injured and 10 homes were damaged, the authorities said. It was not clear if Mr. Shapiro was piloting the Cessna when it crashed or if Mr. Willians was a co-pilot.

Officials on Friday did not release all of the names of the victims, but Mr. Shapiro, 42, was killed as were Emma Lynn Huke, 25, and Kendall Fortner, 24, two employees at Sound Talent Group, the company Mr. Shapiro co-founded, the company said.
