Babysitter murder: More time to quiz suspect
Police have been given more time to question a man arrested on suspicion of murdering a teenage babysitter.
Catherine Wynter, 19, was discovered by her mother on Tuesday in Borehamwood, Hertfordshire. Miss Wynter had been babysitting her niece and nephew.
A court in Hatfield has granted officers until Friday to question an 18-year-old, who was arrested on Tuesday in Borehamwood.
A 26-year-old man from north London was released without charge on Wednesday.
Hertfordshire Police said Miss Wynter had known the two men.
Det Supt Michael Hanlon said police would not give any further details about their relationship but that would come out "in due course".
Search for weapon
The children, aged three and four, were in the house at the time of the murder but were not injured. It is believed they could hold clues about the incident.
In a statement, Miss Wynter's family said she was "a quiet girl who enjoyed life".
"She was a loving auntie to her niece and nephew who she was looking after on Boxing Day", they said.
Officers believe the teenager was attacked at some point between 19:00 GMT on Boxing Day and 08:00 GMT on Tuesday, when they were called to the property in Beech Drive.
A post-mortem examination confirmed that Miss Wynter, who also went by the surname Briscoe and lived elsewhere in Borehamwood, died as a result of stab injuries.
Mr Hanlon said no weapon has been found but a number of searches are taking place.
He said: "Firstly, our thoughts are with the victim's family.
"As you can imagine, this is an extremely traumatic time and they are being supported by specialist family liaison officers.
"We have a team of detectives currently working on the case who are looking at a number of lines of inquiry to establish exactly what happened.
"However, I would like to appeal to the communities of Borehamwood to help us."
