A teenager who stabbed his girlfriend to death on Boxing Day as she babysat two young children was jailed for life with a minimum 25-year term today, Hertfordshire Police said.
Tony Bushby, 19, murdered art student Catherine Wynter, 19, known as Katy, and left her slumped against the fridge in the kitchen of her sister's home.
A post-mortem examination showed she had 23 separate wounds on her body and 13 serious stab injuries - some on her hands as she tried to shield herself.
After the attack Bushby, of Digswell Close, Borehamwood, went to his nearby home with blood on his clothes and hands.
He was convicted by a jury of eight women and four men at St Albans Crown Court.
Miss Wynter was found in a pool of blood by her mother, Joy Davis.
The children, aged three and four at the time, ran down the stairs as Ms Davis arrived and told her: "Grandma, Grandma, Katy's dead."
Bushby left the victim's body in the house overnight with the youngsters.
