The mother and father of missing teenager Bernadette Walker have been charged with her murder.
The 17-year-old had been reported missing from her home in Peterborough by her parents on 21 July after she had not been seen for three days.
Cambridgeshire Police said Sarah Walker, 37, and Scott Walker, 50, have both been charged with murder on Monday.
They have both been remanded in custody and are due to appear before a court virtually.
Detective Superintendent Jon Hutchinson said: "Whilst my team have made significant progress with this investigation in the last few days, we are yet to find Bernadette.
"Therefore my plea is for anyone who has information on what has happened to her, or where she might be, to get in touch as a matter of urgency."
