SAN DIEGO — The National Transportation Safety Board (NTSB) is investigating a fatal plane crash in Tierrasanta that occurred early Thursday morning.

As details emerge, some victims have been identified and questions arise about airport lighting and weather systems.

Emma Huke, 25, was among those on board the Cessna aircraft. Her mother shared on Instagram, “Our beloved daughter Emma was on the plane that crashed in San Diego yesterday. She was traveling with her boss and coworker and few others back from a show at Madison Square Garden for a band they represent… Rest in peace beautiful Emmy.”

Dave Shapiro, 42, the registered owner of the plane and a certified pilot, was also involved in the crash. Shapiro, a music executive, co-founded Sound Talent Group.

Daniel Williams, 39, a former drummer for metalcore band The Devil Wears Prada, is also believed to have perished in the accident.

On Friday evening, the San Diego County Medical Examiner identified Celina Kenyon, age 36, as one of the victims.

The Associate Press identified another victim as Kendall Fortner, 24. A family member confirmed to CBS 8 the death of Dominic Damian, a San Diego resident. A memorial service for Damian is being held Monday in Pacific Beach.

NTSB investigator Dan Baker offered condolences to those affected by the tragedy. He revealed that the pilot did not report any problems or declare an emergency to air traffic control before the crash.

However, Baker disclosed that the weather notification system at Montgomery Field was not operational when the pilot attempted to land around 3:45 a.m. on Thursday. Additionally, approach lights for the runway, which pilots should be able to activate remotely, have been non-functional since October, according to public records.

“There were notices to the airmen stating that there was airport lighting that was out that would have affected the illumination of the runway,” Baker explained.

Foggy conditions with perhaps less than half a mile visibility were reported at the time of the incident.

The NTSB confirmed that the pilot attempted to activate the approach lights during descent by keying his radio microphone several times. In one of the final radio transmissions before the crash, the pilot can be heard saying, “All right, doesn’t sound great but we’ll give it a go.”

The plane struck power lines approximately two miles from the runway before crashing into the Murphy Canyon military housing complex in Tierrasanta.

The NTSB expects to release a preliminary report in the coming weeks, with the final report potentially taking up to two years to complete.
