Alexander V. Long, 23, who once lived near O'Fallon, was sentenced Monday to 41 months in prison for sending threats via email to kill two St. Charles County prosecutors, a detective and a judge and with threatening through Facebook to rape and torture the judge's daughter.

Long pleaded guilty in October to the felony charges in U.S. district court in St. Louis. Judge Carol E. Jackson sentenced him.

He threatened to kill Associate Circuit Judge Norman Steimel, St. Charles County Prosecuting Attorney Jack Banas, Assistant Prosecuting Attorney Gwendolyn Goeke and detective Mikki Straub.

In addition, Long admitted in his guilty plea that he threatened to rape, torture and beat with a baseball bat Steimel's daughter.

The federal charges were preceded by state charges mirroring the federal ones regarding Steimel's daughter.

Long first contacted Steimel's daughter on Facebook using his real name and expressing his affection for her, according to state court records. She asked Long to stop communicating with her and tried to block him, but he created several Facebook aliases and sent her obscene, threatening messages, according to court records.

Steimel said his family's only connection to Long was that he briefly attended the same church.

Long was diagnosed with schizophrenia in December 2010, according to federal court records.

Long is scheduled to be in state court on Friday, Feb. 17.

The FBI and the St. Charles County Sheriff's Department investigated the case.
