Cara Delevingne's house fire mystery: LA Fire Department fail to identify cause of blaze after weeks of investigation

The official cause of Cara Delevingne's late March house fire has been ruled 'undetermined' by the Los Angeles Fire Department.

Investigators have not been able to identify exactly how the 31-year-old model's $7M mansion was set ablaze, according to TMZ. Her parents had previously pointed to an electrical issue.

Despite weeks of investigation by the arson squad, the extensive damage made it difficult to determine the cause and the case has now officially been closed.

The officials did, however, make it clear that there were no signs of foul play. 

The American Horror Story star initially took to her Instagram page to reveal the news of the devastating incident, at the time believing her two cats had perished in the flames.

'My heart is broken today. I cannot believe it. Life can change in a blink of an eye. So cherish what you have,' she wrote.

Cara was in London at the time of the fire due to her role in the musical Cabaret.

Firefighters rushed to the scene after a 911 call was made around 3:57am PST on March 15.

The Studio City mansion was engulfed by flames that spread to the attic, causing severe damage to the sprawling property.

A total of 94 firefighters showed up to fight the blaze, arriving in 13 different fire trucks.

The inferno began at the back of the property, and images revealed that entire parts of the roof had collapsed.

Cara's parents Pandora and Charles were approached by media outside of the Kit Kat Club at the Playhouse Theatre in London ahead of one of their daughter's performances shortly after the ordeal.

When asked what caused the fire, her dad answered that it was 'electrical.'

He also mentioned that 'something fell on a powerline' amid 'very windy' weather in the area.

According to the Los Angeles Times, Cara bought her 8,000-square-foot mansion for a little under $10M in 2019. 

Cara previously owned a Hollywood home with her sister Poppy that they bought from actor Jared Leto — and subsequently sold to singer Usher for $3.4million in September 2022.
