The alternative music community is in mourning after a private jet hit a power line in foggy weather early Thursday and crashed into a San Diego neighborhood, killing multiple people on board.

The San Diego County Medical Examiner’s Office identified three of the six people who were believed to be on a plane that crashed into a residential street in San Diego early Thursday morning.

The airport also had filed a notice to pilots called a Notam, informing them that one of the runways had experienced an issue with the lighting system that guides landing planes.
