A Leesburg woman accused of murder in her husband’s killing will undergo a 30-day mental evaluation before facing a jury trial, according to the Loudoun County commonwealth’s attorney’s office after a hearing Monday in Loudoun County Circuit Court.

Dae Hwang, 57, faces a first-degree murder charge in the March 2 fatal stabbing of her husband. According to testimony at a May 2 preliminary hearing in the case, Dae believed her husband, Kyung Hwang, 63, had fathered a child outside their marriage.

Police were called to the couple’s home on Chickasaw Place in Leesburg shortly after 6 a.m., where they found Kyung’s body in an upstairs bedroom, according to testimony and court records. Dae, who made the call to summon police to the house, told authorities that she had killed her husband, according to testimony and a recording of the 911 call played during the preliminary hearing.

A jury trial in the case had originally been scheduled to begin Oct. 28. That trial has been removed from the court docket to allow for Dae to undergo a 30-day mental evaluation at Central State Hospital in Petersburg, court officials said.

According to an affidavit for a search warrant, Dae had reportedly struggled with depression and was convinced that her husband, a pastor of NOVA First Church, had had a romantic relationship with a female pastor from another church. Police confiscated medical records and prescription medication from the home, according to court records.

At the preliminary hearing in May, several police officers described a grisly crime scene. Kyung was found facedown in a pool of blood with an electrical cord wrapped around his neck, according to testimony. His body showed numerous bite marks and stab wounds, including one that had pierced his skull, authorities said.

At the time of the killing, the couple’s neighbors in the Edwards Landing subdivision told The Post that they were stunned by the gruesome killing. The Korean-born couple, who have two adult daughters, had always been friendly and generous within the community, according to neighbors.

At the hearing Monday, Judge Thomas D. Horne ordered that a report of the mental evaluation’s findings be provided to the court and counsel by Nov. 4, according to the commonwealth attorney’s office. A review hearing is scheduled for Nov. 8.
