(CNN) -- Joann Killeen is president of the Killeen Furtney Group, the Los Angeles, California-based public relations firm that represented octuplet mom Nadya Suleman.



Nadya Suleman had her octuplets through fertility treatments.



Suleman, who underwent fertility treatment, gave birth to six boys and two girls January 26 in Bellflower, California. She already had six children at home.



The Killeen Furtney Group recently stopped representing Suleman because of death threats that came in to the firm's office, Killeen said Monday on CNN's "Larry King Live." Following is an edited transcript of Killeen's conversation with King:



Larry King: When you did this show February 3, you were representing her. Now you're not. Why not?



Joann Killeen: Well, Larry, the number of death threats that came into our office, both by e-mail and voice mail, we had to make a decision about what was in the best interests of our own personal safety and that of our firm.



So we met with the police department on Friday. We filed a criminal report. We provided them with all the information with all the threats. And they told us that we should take this very seriously.  Watch Killeen describe receiving threats »



King: Why you and not her?



Killeen: Well, they've also threatened her. But the majority of the threats are coming to our office. I mean, Nadya doesn't have an e-mail account. She doesn't have a computer. So there's no way to reach her.



So the closest thing they can do is come after me. And they have -- and just in painful, painful ways.



King: How would do you characterize the nature of the threats?



Killeen: Well, they've said to me that I should be put down like an old dog, I should be paralyzed, my client's uterus should be ripped out, she should be put on an island. I mean, Larry, I don't know what's happened with America, but they are really, really angry and letting me know what they think about this issue.



King: Do you take special security precautions?



Killeen: Yes, I do. Yes, I do. We have extra patrols on our street. ... We're very conscious. The police department has been absolutely wonderful to work with. They've given me a special number to call if anybody stakes out my house, as they have before. I've been followed by paparazzi. I'm not a celebrity, so it's a different position for me to be in.



King: How did you inform Nadya that you were no longer. ...



Killeen: Well, we talked on Friday. And she's had death threats, and I've had death threats. And she's very upset that someone would come after us and come after her. I mean she says: "I'm just a mom. I don't know why everybody is so upset. I'm just a mom trying to do the best job that I possibly can."  Watch Killeen explain that no money has been made off the publicity »



King: Why do you think people are so angry -- crazy enough, angry to threaten killing?



Killeen: Well, I think they are frustrated by a lot of things. When the news came out that Nadya was receiving some state disability from an injury and that she was trying to rehab and find a new career and go to school and she also had children at the same time, I think the taxpayers just absolutely flipped out and said, you know, we're paying for this and we're not getting our own fair share of government services. We pay a lot of taxes, the economy is bad, there's no jobs. They're angry.



King: If you're getting threats, what do you imagine she's getting?



Killeen: Well, and I've seen them, because, again, there's no e- mail account. So they're sending them to me. ... People
