Alan Wang, 61, was charged with first-degree murder after his 35-year-old wife Hongyan Yang was found dead on March 8, 2020, officials said.
Naperville Police and Fire Departments responded to their home in the 1100 block of North Mill Street, where Yang was found not breathing, authorities said. She was taken to a hospital, where she was pronounced dead. An autopsy revealed she died of blunt force trauma due to assault.
Wang was initially charged with aggravated domestic battery, and charges were later upgraded to two counts of first-degree murder, police said.
"Authorities learned that in the evening hours of March 7, 2020, Wang and his wife were in their bedroom and when Wang found texts on her phone from another man, he kicked his wife multiple times," the DuPage County State's Attorney's Office said in a news release."
The suspect has been held in custody since his arrest in 2020. A four-day trial for Wang ended September 12, 2025, and a judge has now ruled he is guilty of the murder charges.
Wang's next court appearance will be November 12.
"According to the Centers for Disease Control and Prevention's National Violent Death Reporting System, in 2020, the year Hongyan Yang was murdered, 1,364 women lost their lives to domestic violence," a statement from DuPage County State's Attorney Bob Berlin read in part. "Those thirteen-hundred-plus women are not just a statistic however, they were mothers, daughters and sisters, each of whom had a full life ahead of them. Their tragic deaths remind us we have a long way to go in preventing domestic violence.
