LENOIR, North Carolina: All varieties of sex were offered in the fantasy world Sharon Lopatka concocted for her audience on the Internet.

In some messages, she was an actress prepared to star in whatever type of sex video her fans cared to purchase. In others, she presented herself as an aggressive 300-pound dominatrix.

In the end, Lopatka decided to meet a man she had exchanged sexual messages with -- even though he had said in one that he planned to kill her.

She was bound with rope, made to bleed and then strangled. Her nude body was found Oct. 25, buried near the man's trailer in the mountains of western North Carolina.

Robert Glass, 45, a computer analyst for Catawba County, was arrested the same day and charged with murder. His lawyers say Lopatka died accidentally, during rough sex. Police who examined the Internet messages say the two carried out a bizarre quest in which he promised to kill her and she accepted.

The Washington Post quoted a self-described bondage enthusiasr as saying she tried to stop Lopatka;s apparent death wish. Tanith Tyrr, of Berkeley, Calif., said she and others corresponded with Lopatka in sexually oriented Internet chat rooms.

"She was going into chat rooms and asking to be tortured to death, for real," Tyrr said. She said several men corresponded with the woman but stopped when they concluded that she was serious. Later the person posting messages told Tyrr her name was Sharon and offered her phone number. That number was for Lopatka's home near Hampstead, Md., the Post reported.

Lopatka also arranged in an E-mail exchange to meet a man in New Jersey to be sexually tortured and then slain, law-enforcement sources told the Baltimore Sun. He backed out after Lopatka travelled to New Jersey, it said.

It appears Lopatka used the Internet to present herself as many different people, most of them with unconventional sexual interestd that she was more than willing to share, for a price, the Raleigh News and Observer reported.

Lopatka, who weighed 189 pounds, invented an Internet persona called "Miranda" who she described as a svelte, 5-foot-6, 121-pound cyberwoman. She used the alias while hawking her panties in cyberspace chat rooms, the Carroll County Times, of Westminister, Md., reported.

Investigators have saod they recovered nearly 900 pages of messages exchanged by Glass and Lopatka.

Lopatka arrived in Charlotte by train from Baltimore on Oct. 13. The Caldwell County coroner concluded she died Oct. 16.
