St. Louis ? A woman linked to an online hoax played on a 13-year-old girl who committed suicide and has been vilified for it may be the subject of a deception – someone on the Internet is posing as her and blogging about the case.

Lori Drew’s attorney said Friday that she is not the writer. The St. Charles County sheriff’s department is investigating who is behind the blog postings on Blogger.com to see if a crime has been committed, a spokesman said.

The family believes the postings are an effort to damage its reputation following the death of Megan Meier.

“Any Internet message that purports to be a member of the Drew family is being managed by an impostor and undoubtedly is being done for the purpose of further damaging the Drews’ reputation,” the family said in a statement.

A blog entitled “Megan Had It Coming” surfaced more than two weeks ago. Earlier this week, the person writing the blog claimed the messages were being written by Lori Drew.

The detailed blog lays out Drew’s would-be motives for getting involved with the MySpace hoax against Meier.

Lori Drew’s lawyer, Jim Briscoe, said they have contacted Google Inc., which owns Blogger.com. “We have contacted Google, telling them that was an impostor,” Briscoe said.

A Google spokesman said the company is currently reviewing the impersonation allegation.

Meier thought she was corresponding over MySpace with a cute boy named “Josh Evans” online. The boy never existed. Instead, Drew, her 18-year-old employee and 13-year-old daughter, and Megan’s one-time friend, helped create the hoax.

When messages from the fictional boy and others on the Internet turned cruel, including one stating the world would be better off without her, Megan hanged herself in October 2006.
