Was it a crime?
Let's see.. she committed fraud (impersonating another person, in this case, a minor), harassment, conspiracy to cause harm (this was pre-meditated), willful intent to cause duress (she created the account to get back at the girl for having a falling out with her own daughter), all of which led to involuntary manslaughter (she purposely engaged in activities that, whether intentional or not, directly led to the child committing suicide).
What I find to be truly disturbing is that the state of Missouri couldn't come up with anything better to charge her with than failure to follow MySpace's terms and services.
