A Geneva man has been convicted of killing his wife after he learned last year that she had become emotionally involved with another man.

Shadwick R. King, 47, of the 800 block of Oak Street, Geneva, was convicted Monday night by a Kane County jury of first-degree murder in the July 2014 death of his wife, 32-year-old Kathleen King of Geneva.

The jury deliberated for about 5½ hours before it reached its verdict.

Prosecutors presented evidence that sometime after 5 a.m. July 6, 2014, Shadwick King asphyxiated his wife, Kathleen King, at their home, killing her. Sometime after 6:30 a.m. that day, a Metra Rail conductor reported seeing a female body lying on the Union Pacific Railway tracks in the vicinity of the 200 block of Briar Lane and Esping Park on Geneva’s east side. Geneva police responded to the scene at about 6:50 a.m. and determined that the woman was deceased. The woman was later identified as Kathleen King.

After an investigation, Shadwick King was charged with her murder.

Circuit Judge James C. Hallock set King’s next court appearance for 9 a.m. May 6, 2015, for motions and sentencing. King faces a sentence of between 20 and 60 years in the Illinois Department of Correction.

King remains in custody at the Kane County jail, where he has been held since his arrest in lieu of $1.5 million bail. Bond was revoked upon conviction.

“This is a classic case of domestic violence,” Kane County State’s Attorney Joe McMahon said. “Mr. King was angry that his wife had become emotionally involved, perhaps more, with another man and chose the ultimate act of violence to end the relationship. This is no morality play; this is jealousy and rage. Plain and simple, he killed her.

“When we charged Mr. King with murder, I promised that our office would vigorously pursue justice for Kathleen and her family and friends, and the Geneva community. Although we have done that, we cannot erase the emptiness that her friends, family, and particularly her children will continue to feel going forward. It is not lost on us that Kathleen’s children will now grow up without their parents. That is at least as great a tragedy as Kathleen’s murder.

“Thanks to our prosecution team of Greg Sams, Mark Stajdohar and Kathleen Doyen, as well as Chief Greg Mexin and the Geneva Police Department led by Det. Bob Pech, and the Kane County Major Crimes Task Force for all of their diligent and painstaking work to solve this case.”
