In March 2002, a 13-year-old girl, Millie Dowler, was abducted and murdered. Wikipedia article. Her body was not found until September.
During the time she was missing, friends and relatives left hopeful messages on her cellphone’s voicemail.
Also during that time, a private investigator hired by the News of the World hacked her voicemail and listened to all of the messages. So many messages were left on her voicemail that it became full.
The investigator then started deleting messages he’d already listened to.
This led the family to think that Milly was still accessing her voicemail, and raised hopes that she was still alive. Story.
The editor of the paper at the time, Rebekah Brooks (née Wade), released a statement in 2009:
Glenn Mulcaire is the name of the investigator hired by News of the World, whose 11,000 pages of notes were revealed by police to the Guardian to contain targeting of the Dowler family.
What fucking twisted version of humanity are these people?
Oh yeah, News International. Of which Brooks was recently appointed Chief Executive.
