A Nebraska man was denied bond on Monday, days after he allegedly killed his elderly father with a sword.

William Pae, 53, reportedly admitted to investigators to stabbing his father, Sung Pae, 85, at the family’s home in Omaha on July 3.  Responding officers found William Pae sitting in a chair in the living room before locating his father with stab wounds at the bottom of the stairs in the basement, according to WOWT.

Sung Pae was transported to the hospital, but he succumbed to his injuries, KETV reported.

William Pae allegedly confessed to attacking his father with a sword during an argument. Authorities reportedly discovered the weapon in the home.

William Pae’s public defender claimed their client is reported to have mental health issues. However, specifics regarding his mental health were not disclosed at Monday’s court hearing.

“Some of that is confidential that we can’t talk about, but certainly we’re looking into that aspect, and something we’ve considered in filing this case,” Brenda Beadle, Douglas County prosecutor, told WOWT.

William Pae, who has a clean criminal record, is charged with first-degree murder and assault with a deadly weapon. He is due back in court on August 12.
