A 57-year-old Leesburg woman accused of fatally stabbing her husband believed that he was having an affair, police said in court papers.

Dae Hwang called 911 just after 6 a.m. March 2 and said she had killed her husband, Kyung Hwang, 63, police have said. Shortly before that, she had called her daughter and said that Kyung had confessed to an affair, police said in an affidavit for a search warrant.

Kyung was found dead with multiple stab wounds in an upstairs bedroom of the couple’s home on Chickasaw Place. Dae, who has been charged with first-degree murder, is being held without bond.

Dae was convinced that her husband, a pastor of NOVA First Church, had a romantic relationship with a female pastor from another church, according to the affidavit. She also believed that her husband often held meetings with other pastors who had encouraged the relationship, the document says.

Police confiscated knives, bloody clothes and bedding, a diary, a laptop computer and other items from the couple’s home, the affidavit said. They also searched for Dae’s medical records and medications, according to the document.

An autopsy concluded that Kyung died as a result of stab wounds to his upper body, according to the affidavit. One of the wounds penetrated his skull, the affidavit said.

At an arraignment March 4, Judge Pamela L. Brooks of the Loudoun County Juvenile and Domestic Relations District Court said she would appoint a public defender to represent Dae. The public defender’s office did not immediately return a call for comment.

A preliminary hearing in the case is scheduled for April 25.
