The Sickle Cell Society has started a fundraising campaign for the family of Wembley campaigner Simonne Kerr, who was stabbed to death last week.

The Simonne Kerr Memorial Fund, which has a JustGiving page, will honour her memory and support her family.

John James OBE, the society’s chief exec, said: “We were so shocked to hear the news of Simonne’s death. She was a good friend to the society and will be deeply missed.

“My thoughts are with her mother, siblings and other family members at this difficult time.”

Simonne carried the sickle cell trait. Her son Kavele suffered from sickle cell disease and died from complications in 2015.

She had recently begun a career as an NHS nurse, and was part of the B Positive choir, which made it to the Britain’s Got Talent finals this year.

Desmond Sylva, 40, from Battersea, has been charged with Simonne’s murder. The ex-soldier was living with Simonne at the time of her death.

The fund has so far raised £494. You can donate at justgiving.com/campaign/SimonneKerr.
