BENTON, Ill. (AP) — A Chicago man who federal prosecutors accuse of mailing threats to Southern Illinois University’s Carbondale campus will remain jailed at least a few more days.

A federal judge in southern Illinois on Friday scheduled a hearing for Tuesday in a Benton courtroom about 21-year-old Derrick Burns’ release. His previous court appearances have been in Chicago.

Magistrate Judge Susan Cox on Wednesday ruled Burns could be released but stayed her decision while prosecutors appeal.

Burns is charged with eight felonies linked to what investigators say were threatening mailings sent over a year-long span in 2012 and last year. Prosecutors have said Burns threatened rapes, bombings and beheadings.

The FBI says most of the threatening letters suggested SIU would be targeted.
