Teen killers Kruse Wellwood and Cameron Moffat may share a lust for rape and mutilation, but their relationships with their parents couldn't be more different, according to newly released evidence.

Transcripts of telephone conversations and prison visits between the two boys who murdered 18-year-old Kimberly Proctor and their parents were made public this week. All of the conversations took place in June and July, after the boys were arrested for the March 18, 2010 murder in Langford, B.C.

The transcripts reveal that 16-year-old Wellwood's conversations with mother Nadine typically devolved into angry arguments and attempts at emotional manipulation, while 17-year-old Moffat joked with his parents and listened to their advice.

Kruse and Nadine Wellwood spoke by telephone on June 22, 2010, after Nadine brought her son a suit for court appearances. The pants were too big and the jacket was too small, Kruse says, and he berates his mother for not writing down the correct size.

"You did a very bad job listening to me when I expressly told you my sizes," Kruse says. "I expect that I'd be able to talk to you and I'd be able to tell you something and you'd be able to y'know, at least understand what I told you."

When she protests that the reception during their last conversation was poor, he calls that a "bullshit" excuse.

"Look Mom, there's nothing I can do being in here. So, I'm relying very heavily on you and you've been failing me every single time."

Nadine visited Kruse in prison on July 4, 2010. After a brief discussion about books -- Herman Hesse's "Siddhartha" in particular -- Nadine advises her son to plead guilty to raping and murdering Proctor.

"Look, just keep your fuckin' face out of it. I know what I'm doing. Understand that?" Kruse answers.

His mother tells him that she's afraid of him and that he violated her home by carrying out the brutal attack on Proctor in the family's garage while Nadine was out of the province.

"You have to understand that I can't support you in any way.... Like, if they were to put you on bail I'm not gonna take you in the house.... ‘Cause I don't feel safe," Nadine says.

Her son's answer is anything but reassuring.

"If you weren't safe you would already be dead," Kruse says.

The conversation also turns to Kruse's father and fellow murderer, Robert Dezwaan, who is currently in jail for killing 16-year-old Cherish Oppenheim near Merritt in 2001. Nadine says that father and son have left her equally frightened.

"You can't feel safe in your house when you have to guard why you say and do because you're worried that somebody is going to freak out," she says.

"I had the same thing with your dad.... You guys have no guilt, and no conscience, and some strange sense of, oh what was that word, narcissism."

She goes on to suggest that sociopathy is genetic and that Kruse inherited the gene from his father.

Kruse responds by disagreeing at first, and then suggesting that if what she says is true, she is directly responsible for his crimes.

"If you're telling me that it's the sociopath gene and I can't control it, then you giving birth to me is the cause of everything in my life. Everything I've ever done, I can't control myself," he says.

He later says that he loves his girlfriend more than his mother.

"Do you know why I love her and not you to the same degree?" Kruse asks his mother. "Because she's better than you, better. To me, she has more value as a person ‘cause she gives me more reason to love her."

Moffat talked about fitness with his parents

In contrast, Cameron Moffat seems to have a much easier relationship with his parents, listening to their advice and joking with them about buffing up in prison.

In a June 26, 2010 prison visit, his mother Sarah Moffat told him he should do push-ups in his cell.

"Try and remember about mind, body and spirit and don't get soft, okay?" she tells her son.

Father George Moffat pipes in with an example, albeit not a particularly analogous one: "Nelson Mandela was in jail for 27 years and he got in pretty good shape."

When Sarah tells Cameron, a pudgy boy, that she hopes he has a "six-pack," or a washboard stomach, when he gets out of jail, he answers, "By the time I get out I'll have a 32-pack."

The Moffats bring their son a blank notebook, but advise him to be careful about what he writes in it.

"Don't draw little guys running around with daggers stuck through their heads or stuff like that. That'll get you in shit," George says.

When he talks to his mother again by phone on July 5, 2010, a day before a court appearance, Cameron listens to his mother's advice about sitting quietly and shaving in the morning.

She also suggests he should show some remorse: "If you feel bad about it you need to let people know you feel bad about it, because this is a very bad thing."

Cameron replies that his "dignity" is getting in the way of that.

Despite that brief disagreement, the conversation ends with the two expressing their love for each other, and Sarah promising her son she'd do at least 60 sit-ups that day.

Moffat and Wellwood were both sentenced as adults last week to life in prison with no chance of parole for 10 years for killing Proctor and setting her body on fire near a popular trail.
