Hurst Slaviana is a reporter with the Wichita Eagle and recipient of what police suspect to be a new BTK letter.

The three photos are of a woman's dead body.

The driver's license belongs to Vicki Wegerle, who was killed in her home in 1986 and suspected to be BTK's eighth victim.

Where is he and where has he been?

Two questions police hope to answer.

Lieutenant Ken Landwehr worked BTK as a young investigator in the 1980s.

Now, he heads up a new generation of detectives.

DNA from the Wegerle homicide is matched to a genetic profile found at several of the earlier BTK murders.

Over 1500 men in Wichita are questioned and sampled for DNA.

None, however, match the BTK profile.

Meanwhile, the killer himself is busy writing letters.

Two months after BTK resurfaced, he sends a second letter to the media.

This time, it is the outline of a novel.

Susan Peters is an anchor for Cake and an object of fascination for BTK.

He sends a series of messages for police through her station and expresses his concern for Susan and her co-anchor, Jeff Herndon.

Landwehr has no choice but to take in the messages from BTK.

On July 17th, 2004, BTK delivers a letter to the Wichita Public Library, writing, I have spotted a female that I think lives alone and or is a latchkey kid.

I think fall or winter would be just right for the hit.

Three months later, he sends a chapter of the BTK story, Chapter 2, an alleged biography of his life.

Landwehr continues to go public with the letters, hoping to encourage more communication from the killer.
