An American serial killer who evaded capture 25 years ago has claimed to have carried out another murder.
Police in the Kansas city of Wichita are once again pursuing someone they thought had vanished forever.
The man, known as the BTK killer, claimed responsibility for a number of murders in the 1970s.
He then stopped communicating with police before a new letter arrived this week, claiming responsibility for the unsolved murder of Vicky Wegerle in 1986.
He was known as the BTK killer as his letters often referred to "bind, torture and kill".
Police, who were never able to capture the killer, said they had often wondered what had become of him.
There was speculation that he had died or been imprisoned, and they are investigating people recently released from prisons for a connection.
The newest letter is being investigated, with fingerprint and DNA testing being carried out.
The return of the BTK killer has caused fear among residents of the city.
