SYCAMORE – A man suspected of killing a DeKalb woman in the parking lot at her workplace Friday afternoon was shot and killed by police in southwest suburban Lyons hours later, police said.

Sycamore police Deputy Chief Jim Winters said that the man who was killed in a confrontation around 5:54 p.m. Friday was the only suspect in the slaying of Lidia J. Juarez, 37, of DeKalb. The suspect was later identified as Antonio Juarez, 44, of DeKalb, in a news release from the Sycamore Police Department.

According to the news release, investigators learned Antonio was Lidia's estranged husband, and an active order of protection had been issued against him. Antonio was also wanted on a warrant for violation of an order of protection with no bond set on March 10 and a failure to appear warrant for domestic battery issued on March 24. Investigators believe Antonio stayed at a local hotel prior to the shooting.

Lidia was found shot to death inside her car around 2:05 p.m. in the parking lot at the Illinois Department of Human Services building, 1629 Afton Road. She worked in the building, Winters said.

Winters said there were no witnesses to the homicide and police have not spoken to anyone who reported hearing gunshots. Police had sent an email to workers at a nearby business that said they were looking for two men in connection with the crime.

However, only one of them was suspected of shooting Lidia. When Sycamore officers began their investigation, the DeKalb County Major Case Squad was activated.

Fifteen to 20 patrol officers and investigators worked on the case Friday, Winters said. Their work allowed them to catch up with the suspect.

Police had information about Antonio's whereabouts and shared it with Illinois State Police, who spotted his black 2005 Chrysler 300 a little before 6 p.m., Winters said. According to a news release from the Sycamore Police Department, he was spotted near the 8000 block of Ogden in Lyons.

According to a news release from Illinois State Police, officers began tailing the vehicle after spotting it.

"Multiple agencies assisted in surveillance of the vehicle," an Illinois State Police news release read. "In the area of Ogden Avenue and Joliet Road in Lyons, the suspect began firing at the responding officers."

He was killed when police returned fire, the release said. David Morrone, manager of Salerno's Pizza, at 8005 Ogden Ave. in Lyons, watched the shootout unfold outside the pizzeria.

He said the shooting led to a hail of gunfire, by his count 20 to 25 shots were fired in less than a minute.

"We heard the gunshots first," Morrone said. "We had about 10 employees here. Everyone dropped to the ground. "Whoever was in the car opened fire first. There were two initial shots, then we heard loud shots," he added.

Lidia's death was the first homicide in Sycamore in 2017. Although police said any danger had passed, many people were still in shock at such a violent crime occurring in broad daylight in the community.

Tracy Rogers-Tryba, said she saw her chiropractor in the neighborhood of the crime earlier Friday, and she was shocked when she got a text alert telling her the news.

“I was like, ‘You’ve got to be kidding me,’ ” she said. She said it was jarring, especially less than a year after the double-homicide of Sycamore residents Patricia Wilson, 85, and her son, Robert, 64.

“It seems like our quiet little area is becoming more urbanized,” Rogers-Tryba said.

Bert Fredrick echoed that sentiment.

“It seems like it’s happening a little more than it used to," he said, "and 25 to 30 years ago it seemed more uncommon.”

The case remains under investigation by the DeKalb County Major Crimes Task Force, the DeKalb Coroner's Office and the Sycamore Police Department. The Sycamore Police Department and the DeKalb County Sheriff's Office are also working with the Illinois Department of Human Services for possible care counseling and follow up with employees.
