The woman found stabbed to death Tuesday night in her 25006 Prairie Grove Court home has been identified as Susan Cunningham, a 47-year-old teacher at Plainfield North High School.

The man suspected of killing her is Craig Cunningham, 46, who died about two hours after his wife's body was discovered, Plainfield police said. He was killed when he walked into oncoming traffic on Interstate 55.

According to a news release issued by District 202, Susan Cunningham (nee Triplett) was a physical education and health teacher who taught at Plainfield Central from 2002 to 2006 before moving to Plainfield North in 2006. She has been on medical leave this school year.

Extra counselors have been made available to PNHS students and they'll also be available from 5 to 7 p.m. tonight to offer help to anyone who has been affected by the situation, the release said.

A community vigil will be held from 5 to 7 p.m. at Plainfield North, 12005 S. 248th Ave.

District Supt. Lane Abrell said he hired Susan Cunningham when he was principal at Central, and that she was "a valued member of the staff, great with kids and a very positive person. All District 202 employees mourn Sue's passing."

Original post:

A 47-year-old Plainfield woman was found stabbed to death in her home Tuesday night, and the man suspected in her death -- her husband -- killed on Interstate 55, Plainfield police said.

The unidentified woman was discovered when police did a welfare check at her home in the 25000 block of Prairie Grove Court at about 8:10 p.m., police said in a release on the incident. The victim had been stabbed multiple times and was not breathing; she was later pronounced deceased at Rush-Copley Medical Center in Aurora.

A short time later, the suspect in what police are calling a "domestic-related homicide" was struck by a car when he walked into traffic in the northbound lanes of Interstate 55, just north of Route 126.

He was taken to Adventist Bolingbrook Hospital, where he was pronounced dead at 10:06 p.m., according to the Will County Coroner's Office.

There was no police chase involved in the incident, which is being investigated by the Illinois State Police.

The identities of the victims will not be released until after autopsies are conducted, but Detective Sgt. Kevin McQuaid did confirm that the victim and suspect were a married couple who had lived in the home about six to eight months.
