The sister of a woman stabbed to death as she supervised a children's party at a McDonald's restaurant has called for tougher laws on the sale of knives
Jackie Marshall had worked for McDonald's for 15 years
Jackie Marshall, 54, was attacked at the restaurant in Terminus Road, Chichester, on Saturday.
Gill Colbourne, 55, said she always thought her sister would be safe working somewhere like McDonalds.
A man has been charged with murder and was remanded in custody by magistrates in Chichester, West Sussex.
Mrs Marshall, a grandmother from Southbourne, West Sussex, had worked at McDonald's for 15 years.
Mrs Colbourne, a police constable based on Hayling Island, Hampshire, said new restrictions should be put in place on the sale of knives.
Flowers and tributes have been left outside the restaurant
She said: "As an officer I thought if anything like this was to happen, it would be to me.
"I could never have imagined that my sister would be stabbed working in McDonald's. I thought she would be safe there.
"We're having all these campaigns against guns but I think the same needs to be done with knives.
Mrs Marshall, who had been married for more than 35 years and had children and grandchildren, was from a very close-knit family and was well known in the Southbourne area for her charity work, police said.
A McDonald's spokesman had earlier paid tribute to "a much loved, valued and respected member of our team" and said the company was "shocked and horrified by this tragic death".
Ex-employee Shane Freer, 20, of First Avenue, Batchmere, West Sussex, is due to appear at Lewes Crown Court, East Sussex, on 28 April.
