Thomas Krogman, 68, of Gillette, Wyoming, was sentenced to 39 years in prison on Monday for the first-degree attempted murder of his 72-year-old brother-in-law, Daniel Henry, who was working as the manager of a Motel 6 in Clarkston, Washington. Krogman allegedly traveled from Wyoming to the motel in June 2025 and stabbed Henry eight times in the lobby, an attack that was captured on surveillance video.

Why it matters

The brutal attack at the Clarkston Motel 6 highlights the dangers that motel employees can face, especially those working alone overnight shifts. The lengthy prison sentence handed down to Krogman sends a strong message that such violent crimes will be met with serious consequences.

The details

According to court documents, Krogman approached Henry in the motel lobby, asked 'Remember me?', and then proceeded to stab him eight times. Krogman then fled the scene in a maroon 2011 Chevrolet Malibu, which was later traced back to him through license plate reader cameras. Authorities believe the attack may have been connected to a decades-old family dispute involving allegations of sexual abuse.

  • On June 2, 2025, the attack occurred at the Clarkston Motel 6.
  • In mid-June 2025, Krogman was extradited from Wyoming and booked into the Asotin County Jail.
  • On Monday, Krogman was sentenced to 39 years in prison for the first-degree attempted murder.
