Illinois Police Search for Missing Mom; Husband Thinks Someone Picked Her Up for Exercise Class

Police in Plainfield, Ill., are investigating the disappearance of a mother who has been missing since Monday.

Authorities said that so far there are no signs of foul play.

Lisa Stebic, 37, of Plainfield — an upscale community 20 miles west of Chicago — was last seen early Monday evening.

Her husband, 41-year-old Craig Stebic, said he was working in the backyard and their young children were out when his wife disappeared, according to The Chicago Tribune.

"I can't see her leaving her kids," Craig Stebic told the Tribune. "She's a good mother. She'd do anything for her kids."

Lisa Stebic worked out at the Plainfield North High School track every night, according to the newspaper. Her husband believes someone picked her up. She took only her purse and cell phone; her cell phone and credit cards haven't been used since Monday.

"The last time Lisa was seen was around 6 p.m. Monday," Plainfield Deputy Police Chief Mark Eiting told on Friday. "We're still interviewing people who were friends and acquaintances."

Eiting said the children, who are 10 and 12 years old, were home when Lisa returned from work that day, but were not there when she vanished. He also said that no suspicious cars or people were seen near the Stebic home around the time of Lisa's disappearance.

"We're asking the community for their help," Eiting said.

Authorities hope that someone will see Lisa's picture and call police, said Eiting, "or if Lisa sees somebody has been looking for her, she will contact family or friends or the police department."

Investigators were aware of an Internet posting she made on April 11 looking for "female friends only" to join her in exercise, he said. She listed her "goals" as "increase cardio, tone up, simply get out more, meet new people, just have fun."

"I am a parent and would like to include my children in my health activities," she wrote in the posting, in which she said she was "looking for partners to get out and enjoy nature."

Eiting told that Craig Stebic voluntarily handed over the family computer to police. Authorities still have it in their possession.

"We're actively looking at all leads," Eiting said when asked if police are still searching the computer for any clues.

Craig Stebic said he filed for divorce after 14 years of marriage in January when his wife declared in October that she "didn't want to be married to me anymore," the Tribune reported. Since then, he said, they've lived separate lives in the same house and have not spoken more than five words to each other in five months.

Police were called to the Stebic house once in December during a domestic dispute, according to the Tribune.

Eiting told the paper that it was a "nonviolent domestic trouble call, so it was a verbal altercation between Lisa and her husband. No arrests, no battery."

Eiting confirmed to that the Stebics were going through a divorce and said Craig Stebic was fully cooperating with the investigation.

In 1995, Craig Stebic was charged with two felony counts of unlawful use of a weapon after police stopped his vehicle about 1,000 feet south of two Lincolnshire schools at 9 in the morning, according to the Tribune.

Police found a 10-gauge double-barrel shotgun, a .44 magnum semi-automatic pistol, a Ruger Mini-14 assault rifle and an AK-47 semi-automatic assault rifle in his Toyota pickup.

He was also charged with four misdemeanor counts of unlawful use of a weapon, operating an unsafe motor vehicle and driving while his license was revoked, according to the Tribune.'s Liza Porteus contributed to this report.
