A Missouri mother should serve three years in prison for her role in a MySpace hoax on a 13-year-old neighbor who committed suicide, federal prosecutors said in court documents filed Wednesday.

Assistant U.S. Attorney Mark Krause outlined the government’s position while requesting the maximum sentence for Lori Drew. Probation officials have recommended Drew receive a year of probation and a $5,000 fine.

Krause argued that Drew “coldly conceived of a scheme to humiliate” Megan Meier, a neighbor in a St. Louis suburb, by helping create a fictitious teenage boy on the social networking site and sending flirtatious messages in his name to the girl.

The fake boy then dumped Megan in a message saying the world would be better without her. She hanged herself a short time later.
