Casey-Lyanne Kearney Murder: Hundreds Expected To Attend Charity Concert

Hundreds of people are expected to take part in a charity walk and concert for murdered 13-year old girl Casey-Lyanne Kearney tomorrow.

The teenager was stabbed to death in Elmfield Park, Doncaster, on Valentine's Day after dialling 999 for help. She was found lying injured but later died in hospital.

Britain's Got Talent finalists 2 Grand will perform a benefit gig in Rossington, where Casey-Lyanne lived, to help raise money for her family's funeral costs.

Sallie Lax, 15, one half of the granddaughter and grandfather singing duo, attends McAuley Catholic High School where Casey-Lyanne was also a pupil.

Her stepfather and manager Eddie Van Steen said he expected around 200 people to turn out for the charity events tomorrow.

He said: "The whole village seems to be participating.

"We are all absolutely distraught about what happened. The whole village is talking about it. There is an air of despondency about it.

"People are so distraught about such a young girl. She was totally innocent, it's not like she was doing anything bad. It is a very sad story."

The singers will play at the Styrrup Pub before and after two charity walks to and from the park where Casey-Lyanne was killed. Money will be raised in a raffle, a collection and from CD sales.

Casey-Lyanne had left her home at around midday on Tuesday February 14 and caught the bus to Doncaster town centre, where she intended to meet a friend.

It has emerged that she called police, and a passer-by phoned for an ambulance.

Hannah Bonser, 26, has been charged with her murder and possession of two knives.

Bonser, of Cusworth House, Doncaster, will appear at Sheffield Crown Court on May 10 for a plea and case management hearing, with a provisional trial date set for July 2.

She has been remanded in custody.
