A new jury had to be sworn in at the Catherine Wynter murder trial today.
The new jury was sworn in after a problem was found with the original jury, which has caused a slight delay to proceedings.
Tony Bushby, 19, of Digswell Close, Borehamwood, is accused of the murder of Miss Wynter last year.
Miss Wynter, 19, also known as Katie, was stabbed on Boxing Day at a house in Borehamwood. She was found by her mother the following day.
Bushby has pleaded not guilty to the charge of murder.
