Middlesbrough woman Donna Keogh missing for 15 years
Detectives searching for a Teesside woman who has been missing for 15 years said they were determined to find out what happened to her.
Donna Keogh was 17 when she was last seen in Middlesbrough on 19 April 1998.
Det Supt Peter McPhillips from Cleveland Police said he hoped the 15th anniversary might prompt someone to come forward with information.
"The case has always remained open and we have continued to investigate Donna's disappearance," he said.
"I cannot begin to understand the pain and misery Donna's disappearance must have caused her parents, family and friends."
Anyone with information is urged to call Cleveland Police or if they wish to remain anonymous they can contact Crimestoppers.
