PEORIA, Ill. (AP) — Illinois State Police say investigators are seeking information from the public about a fatal shooting by Peoria police.

Illinois State Police said late Friday they are "aggressively pursuing all leads" regarding the Sept. 20 death of 25-year-old Eddie Russell Jr. They're asking anyone who witnessed the shooting or who has information about it to contact state police. They say callers may remain anonymous.

Peoria police say Russell was a suspected bank robber who was shot after an hours-long standoff at his family's home.

Police Chief Jerry Mitchell says officers fired after Russell exited the home and advanced toward police while holding a raised handgun. The officers involved are on administrative leave.

Russell's family and their lawyer have contradicted the police account. Attorney Andrew Stroth has called the killing an "execution."
