The manhunt for three suspects being sought after an Illinois police officer was shot and killed took a strange turn Wednesday night, as dozens of officers spent hours responding to a reported sighting that police say turned out to be false.

After a search that stretched into early Thursday morning, police said they determined that the woman reporting the sighting was lying, charged her and held her at the county jail.

Kristin B. Kiefer, 30, called police at about 9:20 p.m. Wednesday to report an issue with two men in Volo, Ill., located south of the area where the police officer was killed, according to Det. Christopher Covelli, a spokesman for the Lake County Sheriff’s Office.

Kiefer told police she had pulled over on Route 12 because of car trouble when two men tried to get into her car. The two men — described as one white man and one black man — then fled into a nearby cornfield, she told police.

Police have been searching throughout the area for suspects since Lt. Charles Joseph Gliniewicz, an officer in Fox Lake, Ill., was fatally shot Tuesday morning.

Authorities converged on Volo after the report Wednesday night, with the Lake County Sheriff’s Office setting up a perimeter and about 85 federal, state and local law enforcement officials joining sheriff’s deputies in the search. Police also deployed 11 search dogs and called in air support to look from above, but the dogs could not find a scent, and nothing was seen from the skies.

All told, police searched the area for about five hours, pushing the search into early Thursday morning and the manhunt’s third day.

Police investigated and eventually concluded that Kiefer had lied about what happened, Covelli said Thursday morning.

“Kiefer informed detectives she fabricated the events as she wanted attention from a family where she is employed as a nanny,” Covelli said in a statement. “Additionally, she indicated she chose this location to fabricate the event, as she was aware of the death of a police officer in the area.”

Kiefer has been charged with one felony count of disorderly conduct and one misdemeanor count of disorderly conduct for falsifying a police report. She was taken to the Lake County Jail and is being held until a bond hearing can be held, Covelli said.

Police say they are continuing to look for the three suspects Gliniewicz said he was chasing on Tuesday morning before he stopped radioing in and was found with a gunshot wound. The three suspects were described only as two white men and a black man.

“We are making progress,” Cmdr. George Filenko of the Lake County Major Crimes Task Force said during a news conference Wednesday afternoon.

Filenko said authorities are canvassing the area, speaking to people and working through hundreds of tips coming in from the public. He emphasized the importance of these tips as invaluable to this kind of search. On Wednesday, he said that about 100 investigators were working on the case.

“I’m not going to set a time limit on this,” he said. “I have a murdered colleague, a police officer, and we’re not going to stop.”

Schools in the region were closed Wednesday due to the search, but the school districts jointly decided to reopen Thursday after police told them it was safe, according to a statement from the Gavin School District.

A vigil was held Wednesday night to honor the father of four, a decorated officer known to many as “G.I. Joe.” Fox Lake is a small community of about 10,000 residents located a little more than an hour north of downtown Chicago. Gliniewicz spent three decades as an officer with the Fox Lake police, according to village officials.

“The loss of Lt. Charles Joseph Gliniewicz has left a large void in our community,” Fox Lake said in a statement. “A void that can never be filled.”

Gliniewicz is the 24th police officer shot and killed by a suspect this year, according to the Officer Down Memorial Page, a nonprofit organization that tracks line-of-duty fatalities.

While the number of police officers shot and killed is down from the same point last year, Gliniewicz’s death comes shortly after the high-profile killing of a Texas sheriff’s deputy who was gunned down while getting gas in suburban Houston.

That shooting drew renewed attention to the tension law enforcement officials say they feel amid ongoing protests against how police use deadly force.

Attorney General Loretta E. Lynch spoke Wednesday at a conference in Washington about the importance of standing up for the safety of police officers, referencing the slain officers in Texas and Illinois as well as the two officers killed in Louisiana last week.

“I strongly condemn these recent and brutal police shootings in Texas and Illinois,” Lynch said, according to her prepared remarks. “We have had four more guardians slain and frankly our hearts are broken over this. I offer the families of these officers my condolences and I ask that all of us come together and keep them in our prayers.”

Lynch tied these deaths to recent shootings that have captured national attention, including the killings of journalists in Virginia, military members in Tennessee, moviegoers in Louisiana and church parishioners in South Carolina.

“We have seen violence strike at all segments of our community,” Lynch said. “It is a sad fact now that no one is safe.”
