Witnesses Detail BTK Brutality

(Editors note: Testimony detailing the murders is graphic and may be objectionable to some readers.)

"What's going to happen to me?" she asks.

Rader: "Well, honey, you're going to be in heaven with the rest of your family."

Rader then hanged the girl and masturbated over her body.

Wearing a dark suit and occasionally taking notes on a legal pad, Rader looked on as KBI special agent Raymond Lundin said the killer told authorities in an interview after his Feb. 25 arrest that he targeted Josephine because he was attracted to Hispanics.

"He said that he has always been attracted to Hispanic looking people — dark eyes, dark hair, dark skin. He said Josey was the one who caught his eye and she was his target," Lundin said, noting that Rader also told him he was attracted to "younger women."

"I don't know how you call an 11-year-old a younger woman," Lundin said.

Josephine; her father, Joseph, 38; her mother, Julie, 34; and her brother Joseph II, 9, were strangled in their home in January 1974. The three remaining Otero children, who had came home from school that day to find their parents and siblings dead, were in the courtroom. When prosecutors showed the crime scene photo of Josephine, Charlie Otero began crying and buried his head on his lap.

Rader said that basements are the best place to hang someone because it's like a dungeon and solid, according to testimony. Rader watched Josephine struggle for her life.

Rader, a 60-year-old former church congregation president and Boy Scout leader, pleaded guilty in June to the 10 murders that haunted Wichita over three decades beginning in the 1970s.

CBS News 48 Hours correspondent Erin Moriarty, who has spoken with Rader several times,

Moriarty reports that due to Rader's docile nature, his prosecutors call him the "gentleman serial killer." He's so ordinary and calm, Moriarty says, one must be reminded that he is an admitted serial killer. He speaks in a monotone, using the same matter-of-fact tone — whether he is talking about his work as a local dogcatcher or his method for killing people.

Despite his cool nature and quiet speech, Rader may relish the limelight. The BTK killer taunted media and police with cryptic messages during a cat-and-mouse game that began after the first murder in 1974.

BTK resurfaced in 2004 after years of silence with a letter to The Wichita Eagle that included photos of a 1986 strangling victim and a photocopy of her missing driver's license. Rader told KAKE-TV — the Wichita station with which he had often communicated as "BTK" since the 1970s — that he was working on an emotional statement for his sentencing.

BTK was the killer's own moniker for "Bind, Torture, Kill." In a haunting prophetic message sent to KAKE in the 1970s, BTK wrote: "There is no help, no cure, except death or being caught and put away."

Rader will almost certainly die behind bars for the murders committed in the Wichita area from 1974 to 1991.

Prosecutors want Rader to get the longest possible sentence — a minimum of 175 years without a chance of parole. To support that, they plan to present 10 or fewer witnesses, along with photos of the crimes and other evidence, said Georgia Cole, spokeswoman for the District Attorney's Office.

The state had no death penalty when the crimes were committed.

Judge Gregory Waller must rule on whether he will serve his 10 sentences consecutively or concurrently.

In his confession, Rader said sexual fantasies drove him to commit the killings, which he referred to as his "projects." Days after the confession, Rader called KAKE from prison and told them he had picked out an 11th victim before he was caught.

Prosecutors have presented photos and other pieces of evidence. Those items include a knife and a gag Carmen Otero, one of the surviving Otero children, cut off her mother, BTK victim Josephine Otero, with toenail clippers more than 30 years ago.

Carmen Otero, watching this morning's proceeding in the courtroom, wiped tears while listening to testimony.

Rader, a former president of his church, blamed the killings on a "demon" that got inside him at a young age.

But, Moriarty reports, what is most unnerving about Rader is his ability to hide his dark side from people he knows. He never gave any details of his killings away in 34 years of living in the community he killed in.

Rader said his wife often spoke of her fear of the BTK killer. He comforted her by suggesting that she "just keep the doors locked. I wasn't really worried," he told Moriarty, "since I knew I was the one doing the killing."

With the criminal case winding up, Rader now faces a series of lawsuits from the families of his victims seeking to keep him from profiting from his crimes.

Rader's ex-wife, Paula, has filed a petition to intervene in those cases, primarily to protect proceeds from the recent sale of their home.
