Although it is not included in the series, there is little disagreement as to how Halbach ends up at the Avery compound following her last visit on October 10, 2005. Steven Avery called Auto Trader the morning of October 31, 2005 and requested Halbach on behalf of Barb Janda, Steve Avery’s sister, to be there that afternoon to take photos of the van she was selling. In response, Halbach called Janda’s home phone and left a message asking for a confirmation call. Whether or not Janda was actually listing the van for sale is not clear, but the fact that Avery attempts to call Halbach’s cell and Auto Trader after it appears she has not arrived by 2:27PM (her voice-mail left on Janda’s landline) her proposed time of “around 2 or maybe later” by intentionally blocking his cell phone number using the *67 feature is suspect. Avery will call her cell again with his open cell line.
Liane Marie Cartman , originally voiced by Mary Kay Bergman and later by Eliza J. Schneider and April Stewart , is the generally sweet-natured mother of Eric Cartman ; though in later seasons, she has been shown to be a more proactive mother who does not tolerate his antics or foul language. Her promiscuity , often with total strangers, was a running gag initially. It seemed as though all of the adults in South Park had slept with her (including the women). Although in episode 7, she is indicated to be a " crack whore ", she says in " The Poor Kid " that she has not done drugs in some time, and works two jobs, even though she and Eric are the second poorest family in South Park (at least of those whose children attend South Park Elementary) after Kenny McCormick 's.  It is first revealed that she is a hermaphrodite (and so is Eric's father), though in episode " 201 " it is revealed that Eric's real father is Jack Tenorman , the father of his nemesis Scott Tenorman a member of the 1991 Denver Broncos, and the ruse about her being a hermaphrodite was made up to maintain the Broncos’ reputation since “they were having a good year”
