A £10,000 cash reward has been offered to help solve the murder of a teenager who has been missing since for more than two decades.
Donna Keogh disappeared from Middlesbrough in 1998 after she was last seen at a house party.
She was just 17 when she disappeared on April 19, 1998 and would have celebrated her 40th birthday last month.
Crimestoppers has offered the reward in an attempt to give Donna's family closure after suffering years of heartbreak.
Ruth McNee, North East Regional Manager at the charity, said: “Donna’s parents are desperate to know what happened to their much-loved child and time is not making this torment any easier.
"We are appealing to anyone with information to do the right thing and to speak to our charity 100 per cent anonymously. You can make all of the difference in getting justice for Donna and her family and you may stop somebody else from being harmed.
“We hope that allegiances have changed over the years and somebody is now ready to speak about what they know. We believe that answers lie in the local community. No information is too small to tell our charity anonymously and you may be eligible for a reward."
Despite numerous Cleveland Police investigations over the years, she has never been found, and what began as a missing persons inquiry is now being conducted as a murder investigation.
Her family is tormented by questions which remain unanswered to this day.
In 2006, Donna's parents lodged official complaints against Cleveland Police in relation to the inquiry.
A new inquiry was launched in 2016, with hundreds of people interviewed, carrying out thousands of lines of enquiry.
Detective Superintendent Paula Dewell said: "They have made much progress over the years and remain committed to finding out what happened to Donna and identifying who is responsible for her death.
"The investigation team still believe there are people in Teesside who know what happened to Donna and have evidence about the people who are responsible.
"We would urge anyone with information to search their conscience and come forward to help the investigation."
