In June of 2005, the media descends on Wichita to watch BTK in open court.

For almost an hour, Rader wanders through his past, educating a packed courtroom on the business of a serial killer.

He begins with the murder of an entire family.

Rader often used a ruse to gain his victim's trust.

Vicki Wegerle was home with her two-year-old son when she got a knock on the door.

It was BTK, dressed as a telephone repairman.

Dennis Rader describes 10 separate acts of murder and pleads guilty to each.

All that remains is Dennis Rader's sentencing and a final day in court.

On August 18, 2005, District Attorney Nola Folston explains to the world why Dennis Rader should be put away for the rest of his life.

At Dennis Rader's sentencing hearing, each of the detectives in the task force takes the stand, each offering his own bit of BTK horror.

Tim Ralph shares the killer's final words to a victim.

Lieutenant Ken Landwehr testifies last, providing details on the erotic fantasies that underpin BTK's crimes.

After laying out the motive underpinning Rader's crimes, the state turns the court over to family members, who get a chance to speak directly to BTK.

Finally, it is Rader's moment on the stand.

He begins with a twisted eulogy of sorts, attempting to draw a bond between himself and those he has killed.

Then, as if giving an acceptance speech, BTK gives thanks to those who have helped.

Rader closes with a final wish for his own salvation.

Judge Gregory Waller sentences Dennis Rader to the maximum allowed, 10 consecutive life sentences, and what is known in Kansas as a hard 40, a sentence of 40 years with no possibility of parole.

For the families of Raider's victims, a measure of justice after decades of uncertainty doesn't make them whole.

But it is enough to begin the healing process.
