St. Louis ? A 21-year-old woman accused of sending a vulgar text message to a 17-year-old girl is one of the first cases brought under a law against cyberbullying spurred by the suicide of a teenage girl following cruel messages on the Internet.

The 2006 death of 13-year-old Megan Meier prompted Missouri lawmakers to update state harassment law earlier this year so that it now covers bullying and stalking done through electronic media, like e-mails or text messages.

A handful of cases related to electronic communication have been filed statewide since the law took effect Aug. 28. Prosecutors do not track harassment cases based on the type of communication method used, so could not provide an exact count in recent days of how many people have been charged because of the new provisions.

In one of the new cases, Nicole Williams is accused of using electronic communications to harass a teenager in a dispute over a boy. Williams is scheduled for arraignment on one count of harassment on Jan. 8.

She allegedly sent the text message to the 17-year-old she had not previously met because she heard the girl had a physical encounter with her boyfriend. The two had just been talking, police said.

The 17-year-old girl received voice messages with lewd and threatening comments, including some that called her by the name “pork and beans” and threatened rape. Williams told police others sent those messages from her phone, according to a probable cause statement.
