Bond Set at $ 850,000 for Naperville Man Charged Aggravated Domestic Battery in Connection With Wife’s Death

(The following is a joint press release sent in conjunction with the DuPage County State's Attorney's Office.)

DuPage County State’s Attorney Robert B. Berlin and Naperville Chief of Police Robert Marshall announced today that bond has been set for a Naperville man charged with Aggravated Domestic Battery (Class 2 Felony) in connection with the death of his wife. Alan Wang, 55 (d.o.b. 3/20/1964) of 1103 N. Mill Street, appeared at a bond hearing this morning in front of Judge Ann Celine O’Hallaren Walsh, who set bond at $850,000 with 10% to apply.

On March 8, 2020, at approximately 4:50 p.m., personnel from the Naperville Police and Fire Departments responded to a call at the couple’s residence regarding a female who was not breathing, later identified as Hongyan Yang, 35 (d.o.b. 6/10/1984). The victim was immediately taken to a local hospital where she was pronounced dead at 5:54 p.m. Following an investigation conducted by the Naperville Police Department into Yang’s death, it is alleged that in the evening hours of March 7, 2020, the defendant and his wife were in the couple’s bedroom when the defendant kicked the victim multiple times on her legs causing deep soft tissue hemorrhaging. The following day, a relative of the couple called 9-1-1 when it appeared that the victim stopped breathing.

“This case is a terrible reminder that domestic violence continues to be a serious problem that demands our attention,” Berlin said. “While it is generally believed that domestic violence cases are underreported, Federal authorities estimate that in the United States there are still more than five million incidents of domestic violence every year, with as many as one in four women becoming a victim of domestic violence. These numbers are more than alarming particularly when you consider not only the physical and emotional harm endured by the victim, but also the effect domestic violence has on families and the entire community. I would like to thank the Naperville Police Department for their work on this very sad case. I would also like to thank Assistant State’s Attorney Amanda Meindl for her efforts in securing charges against Mr. Wang.”

“This was a brutal crime, and our thoughts are with the victim’s family as they cope with this tragic loss. I want to extend my gratitude to the police officers and investigators who dedicated so much time and effort on this case to get justice for the victim and to ensure the offender is held accountable for his actions,” said Naperville Police Chief Robert Marshall. “Domestic violence remains one of the top offenses for which we arrest people in Naperville, and our department is committed to helping victims of domestic violence find safety before something as tragic as this incident occurs. From our victim advocate and social services team to the resources available on our website (, we want victims of domestic violence to know that the Naperville Police Department has resources to help you. We will help you. You are not alone.”

The investigation into Yang’s death continues.

Wang’s next court appearance is scheduled for April 6, 2020, in front of Judge O’Hallaren Walsh for arraignment.

Members of the public are reminded that this complaint contains only charges and is not proof of the defendant’s guilt. A defendant is presumed innocent and is entitled to a fair trial in which it is the government’s burden to prove his or her guilt beyond a reasonable doubt.
