HARVEY | State police raided the Harvey Police Department for four hours Wednesday, confiscating cases of items in connection with a Cook County investigation.

The Public Integrity Unit of the Illinois State Police entered the department with a subpoena to take specific police records, Harvey Mayor Eric Kellogg said in a written statement.

The raid started early Wednesday afternoon and lasted until about 5 p.m., when investigators loaded six to eight hard cases into a sheriff's department unmarked car.

None of the investigators would answer questions or offer information.

Illinois State Police are assisting the Cook County state's attorney's office in the investigation, said Master Sgt. Luis Gutierrez, the agency's public information officer. He confirmed officers removed materials from the Harvey Police Department, but he would not discuss what those materials included.

Andy Conklin, spokesman for the Cook County state's attorney's office, would not comment on the investigation.

Investigators will receive support and "full cooperation," Kellogg said in his statement.

"As I have always stated, if there are any findings of misconduct of any of our officers or employees, I will push for the immediate termination of the individual or individuals involved. Corruption and police misconduct is not and will not be tolerated by any means."

Deputy Chief Denard Eaves said he planned to speak with journalists, but he left the station Wednesday afternoon without doing so. Repeated calls to Harvey Police Chief Andrew Joshua and to Kellogg were not returned Wednesday.

The state intervention comes months after the Harvey City Council passed a resolution that sought an investigation into the department after reports surfaced about a gun that disappeared while in police possession. A former Harvey police detective faces several charges in connection with that case.

In addition, at least 38 of the 52 murders in the city during the past four years remain unsolved. The Police Department is also the target of several lawsuits filed in state and federal courts.

U.S. Rep. Jesse Jackson Jr., D-Chicago, who pushed for an investigation after allegations about the missing gun surfaced, applauded Wednesday's raid.

"It's a sad day when police departments have to police other police departments, but in this case, I embrace and welcome it," Jackson in a statement. "The law-abiding citizens and officers who honor the badge need to be protected, while the officers who fail to honor it need to be exposed and prosecuted. Mayor Kellogg must be held personally responsible for today's events, which were completely avoidable."

Sixth Ward Alderman Ronald Waters, who said Wednesday evening he'd been unable to contact the mayor in regard to the state police's intervention, last fall sponsored the resolution that requested the mayor and police chief allow a state audit of the Police Department,

The Harvey City Council passed the resolution, but Kellogg stonewalled the request, said Waters, who is one of several residents running against the mayor in this spring's municipal election.

"It's very ironic that the very agency we asked to come in to audit the department was the one that came today with subpoenas," Waters said. "It's a sad day for the great city of Harvey, but we will overcome this. One individual will not dictate the course of history in Harvey."

Anthony L. McCaskill -- another mayoral candidate -- called for Kellogg to resign.

"Justice is definitely taking place here," he said. "Unfortunately, 48 people had to die first."
