A Chicago man charged with mailing threats of rapes, killings, bombings and beheadings to Southern Illinois University's Carbondale campus was ordered released Wednesday on his own recognizance.
A judge said Derrick Dawon Burns, 21, is not a threat to the community but required a mental health evaluation be conducted.
Burns, being released in the case of his aunt, will be required to wear an electronic monitor.
Burns has been jailed since his arrest Monday on eight federal felonies related to the mailings investigators said were sent over a yearlong span in 2012 and last year. He's scheduled for a detention hearing Wednesday.
The FBI says most of the threatening letters suggested SIU would be targeted, with some of them bearing the signoff "Terrorist of America" or "Terrorist for Al-Qaida."
Burns drew investigators' scrutiny in July when he separately called SIU-Carbondale police and the FBI and insisted a man called "Big Russ" told him about the threats. The FBI alleges investigators traced those calls back to Burns and fingerprints on four of the seven threatening letters later were matched to Burns.
A spokeswoman for the school says Burns studied criminology and criminal justice at SIU-Carbondale, but is no longer a student.
The case will likely be transferred to the southern district of Illinois where the crimes are alleged to have occurred.
Online court records don't show whether Burns has an attorney.
