Connor Chapman has pleaded not guilty to the murder of beautician Elle Edwards in a Merseyside pub on Christmas Eve.
Ms Edwards, 26, was celebrating with friends when a gunman opened fire at the Lighthouse pub in Wallasey Village, Wirral, shortly before midnight.
She was not believed to have been the intended target of the attack, which left four men injured.
Chapman pleaded not guilty at Liverpool Crown Court.
In an interview with Sky News earlier this year, her father Tim Edwards said: “She was beautiful looking and she was a great hugger. She was just a fantastic human being with a heart of gold.”
The order of service at her funeral asked for donations to the Elle Edwards Foundation in her memory, and Mr Edwards said he hoped the foundation would combat gun violence in the region.
