Cathy Seipp was dying.

The 49-year-old newspaper columnist and conservative blogger, who had come from Manitoba, Canada, to become the sharp-tongued doyenne of the Los Angeles media scene, was only hours away from losing her years-long fight with cancer, leaving behind a 17-year-old daughter, a lifetime of work as a plucky and plain-speaking wordsmith, and the respect of colleagues from both sides of the political spectrum.

But what was supposed to have been a dignified end for a long-suffering single mom instead turned into what friends called a disgustingly public travesty, an example of the current Wild West atmosphere of Internet privacy issues, and a sordid showcase of just how far a beef can go.

Just hours before her death, "Cathy Seipp" suddenly seemed to undo decades of hard work with an oddly written letter posted on the Web site, www. cathyseipp.com. In what came off as more bizarre rant than heartfelt apology, her supposed "very last blog entry" called her years of journalism a "shoddy," "despicable" and "irresponsible" career as a "fourth-rate hack." Her political stance? All a mistake...

Friends were horrified. They quickly realized that the letter was the work of an infamous character known as "Troll Dolls" who'd positioned himself as the blogger's archenemy and bought the domain name www.cathyseipp.com years earlier (Seipp's real Web site is www.cathyseipp.net). Troll Dolls is really Eliot Stein, a 54-year-old former online talk-show host and stand-up comedian who had taught Maia in a journalism class for a brief period in 2004, and who blamed Maia and Seipp for his departure from the school after only five weeks...

"He's a genuinely weird dude [who wrote] a rambling, odd, mean, totally cruel series of posts... designed to trick well-wishers, as Cathy lay dying, into reading a torrent of rage and bitterness against her," Rob Long, an L.A. television writer and longtime friend of Seipp's, wrote in an e-mail. "Just immensely cruel. It was easy to ignore when she was alive, but as she died it became intolerable - thousands and thousands of people wanted to reach out to Cathy and her family in the days surrounding her death, and this guy tricked, perverted and deeply hurt them. And for what? A years-old grudge?"

Eliot Stein, while Maia's schoolteacher, also posted nasty comments on Maia and Cathy's blogs; when Maia's school got rid of him, he came to work in a tuxedo on his last day and made sure to tell every class that his departure was Maia's fault, which he must have known would lead to her being bullied and humiliated (which is exactly what happened).
