Charges Upgraded to First Degree Murder Against Naperville Man in 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 charges have been upgraded to First Degree Murder against Alan Wang, 56 (d.o.b. 3/20/1964) of 1103 N. Mill Street, Naperville. Wang is accused of beating his wife to death earlier this year. On March 11, 2020, Wang appeared at a bond hearing where bond was set at $850,000 with 10% to apply. He was originally charged with one count of Aggravated Domestic Battery (Class 2 Felony.) Yesterday, Wang was indicted on two counts of First Degree Murder in addition to the existing count of Aggravated Domestic Battery.

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. The following day, a relative of the couple called 9-1-1 when it appeared that the victim stopped breathing. The findings of an autopsy conducted by DuPage County Coroner Dr. Richard Jorgensen’s office led to the upgraded charges.

“The autopsy conducted by the DuPage County Coroner’s Office concluded Hongyan Yang died as a result of internal bleeding,” Berlin said. “With a cause of death now known, justice demands that the charges against Mr. Wang support the allegations that he is responsible for her death. I commend the DuPage County Coroner’s Office for their outstanding efforts in identifying Hongyan Yang’s death. 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 Attorneys Amanda Meindl and Alexandria Levan for their efforts in securing the appropriate charges against Mr. Wang.”

"This was a brutal and tragic crime, and I want to thank our officers and investigators, the DuPage County Coroner’s Office as well as the DuPage County State's Attorney's Office for their diligence in investigating this case in order to get justice for Mrs. Yang," Marshall said. “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. You are not alone.”

Richard Jorgensen, MD, DuPage County Coroner, appreciates the thorough and professional investigation by Deputy Scott Quinn and Katherine Little. “The experience and training of the Coroner Deputies is brought to the fore in situations like this where the investigation, preservation and collection of evidence is essential to bringing justice for the deceased,” Jorgensen said. “Additionally, the excellent evaluation and examination by Chief Forensic Pathologist Hilary McElligott, MD, was integral to the investigation and presentation of factual evidence to the State’s Attorney for charging and prosecuting this offender.”

Wang’s next court appearance is scheduled for July 20, 2020 for status in front of Judge Ann Celine O’Hallaren Walsh.
