As the fashion world continues to mourn the death of Alexander McQueen, post-mortem results confirm that the designer died from asphyxiation and hanging.

At an official inquest at Westminster Coroner’s Court in London on Wednesday, it was revealed that Lee Alexander McQueen hanged himself in a wardrobe closet at his Mayfair apartment, leaving a suicide note by his side. His sister, Janet McQueen, was called to identify the body, the BBC reports.

A representative of the Metropolitan Police said at the five-minute initial hearing that there were no suspicious circumstances, while the coroner’s office said the full report of the post-mortem examination was not yet available. The inquest was adjourned until April. 28.

A rep at the Alexander McQueen fashion house tells PEOPLE, “There has been no date set for a memorial but we hope to know more shortly,” and adds: “It will be very low-key.”

The family laid to rest the designer’s mother, Joyce McQueen, in East London only last Friday, the day after Alexander McQueen’s body was discovered.

As a mark of respect to McQueen, Lady Gaga toned down her performance at the Brit Awards in London on Tuesday night, and, the Sun reports, converted her dressing room into a shrine to her close pal. Photos of the fashion icon were pinned to the walls.
