CHICAGO (WMBD) — Ben Crump, a nationally-renowned civil rights attorney is demanding the Federal Bureau of Investigation (FBI) have exclusive control over the investigation into the death of Illinois State University graduate student Jelani Day.

Crump and co-counsel B’Ivory LaMarr said they will hold a press conference on Friday, Dec. 3 at the Rainbow Push Coalition located at 930 E. 50th St. in Chicago, where they will issue the demands.

Previously, Peru Police Chief Bob Pyszka said the FBI is not taking the lead in the case, but the agency is helping with the investigation.

An FBI Chicago spokesperson previously told WMBD, “The FBI is always willing to assist at the request of local law enforcement and is in communication with the Peru Police Department to provide resources as needed. Department of Justice policy prevents us from further commenting on investigations.”

Throughout the investigation, Day’s family has asked law enforcement to get the FBI involved.

Day was reported missing in late August. His body was found about two weeks later in the Illinois River. LaSalle County Coroner Richard Ploch said the cause of Day’s death was drowning, but the manner of death has yet to be determined.
