When Lisa Lambert was questioned by Forrest Sawyer in an interview done by 20/20 regarding the case her answers were nearly the same. 

Forrest Sawyer: (on camera) How do you feel about Laurie Shows death?
Lisa Michelle Lambert: It's very sad.
Forrest Sawyer: I hear you say it, but I don't see you feel it.
Lisa Michelle Lambert: I am very sorry about what happened. But it's - I wasn't the cause of it. I don't know what else to say.

Are adults born like this as infants or are they taught this by bad parents? Several studies done by numerous leaders in the psychiatric field have yet to determine positively one way or the other, but it is thought to be a combination of both. A case study regarding Gary Gilmore, a man who murdered two young men in cold blood and then refused to appeal his death sentence is a good place to begin. Gilmore was executed in 1977. 

What made him turn into a killer, while his four brothers were well adjusted, productive men? One of Gary's brothers traced Gary's violent tendencies back to their childhood which consisted of emotional and physical neglect, religious rigidity, and bouts of physical abuse that can be traced back as far as both sets of grandparents. While it is clear that Lisa Lambert was not physically abused her home as a child, could it be that she was emotionally neglected? So we come back to the same question, was she born this way, was it bad parenting or a combination of both? The main thing all appear to have in common is a total lack of remorse for their crimes, a characteristic blatantly shown by Lisa Lambert. 

Let's take a look at a mental defect termed Anti Social Behavior. Anti Social Behavior is characterized as:

A. A pervasive pattern of disregard for and violations of the rights of others occurring since age 15 years, as indicated by three or more of the following: 

- Failure to conform to social norms with respect to lawful behaviors as indicated by repeatedly performing acts that are grounds for arrest.
- Deceitfulness, as indicated by repeated lying, use of aliases, or conning others for personal profit or pleasure
- Impulsivity or failure to plan ahead
- irritability and aggressiveness, as indicated by repeated physical fights or assaults
- Reckless disregard for safety of others
- Consistent irresponsibility, as indicated by repeated failure to sustain consistent work behavior or honor financial obligations
- Lack of remorse, as indicated by being indifferent to or rationalizing having hurt , mistreated or stolen from another. 
B. The individual is at least 18 years of age.
C. There is evidence of Conduct Disorder with onset before the age of 15.
D. The occurrence of antisocial behavior is not exclusively during the course of schizophrenia or manic episode.

However, in 1970 Otto Kernberg pointed out that the antisocial personality was fundamentally narcissistic and without morality. He called it malignant narcissism, which included a sadistic element. The self love is central seems correct but this concept failed to go very far with clinicians who needed practical instruments. It was Hare and his associates who made the greatest impact on assessment and treatment. They clarified a set of diagnostic criteria that offered a practical approach. Psychopathy was defined as a disorder characterized by:

Lisa Michelle Lambert: I think that the police officers are afraid that my daughter is one of their children. That's what I think.
Forrest Sawyer: That's right. Lisa Michelle says they're really after her because one of the rapists is the father of her child. The only problem with that? Her ex-boyfriend Lawrence Yunkin.
Lawrence Yunkin: I got court records that 99.98 percent chance that I'm the father. I mean, you can't get any closer than that.
Forrest Sawyer: The probability of paternity is 99.98 percent. The Roche Biomedical Laboratories show it this way.
Tina Rainville: We contacted them. And we were informed that it was there regular practice to destroy all the records. 
Forrest Sawyer: Are you suggesting that the Roche Biomedical Laboratories might be involved in the conspiracy? 
Tina Rainville: I have no idea. But we were not able to get any of the underlying records to support that.
Forrest Sawyer: A laboratory spokesman says that's not true. The complete records are still available. So, if, as the police claim, Lisa Michelle is lying about the murder, what really happened? 

When Lisa's parents were aware of the condition of their child (lying, stealing, ect) rather than seeking treatment for her, they turned her loose into society for her anger and frustration to fester. It is clear that if caught in early childhood, the condition is preventable to come extent. It is a parents job to socialize their children and to learn the observational and listening skills necessary to detect when children are deviating into harmful patterns. It is NOT an issue of placing blame but rather detecting the "nutritional" imbalance and setting it right. In the case of Lisa Michelle Lambert and so many others like her, this was not done.
