Wyoming Woman Found Not Guilty in Brother’s Motel 6 Stabbing Plot

Phyllis Krogman, a 65-year-old resident of Gillette, Wyoming, was found not guilty on May 9, 2026, of charges related to a plot to stab her brother at a motel in Washington state.

A jury in Asotin County acquitted Krogman of attempted first-degree murder and conspiracy to commit attempted first-degree murder. The verdict followed a trial concerning a violent attack that occurred in July 2025.

The case centered on the stabbing of Daniel Henry, Krogman’s brother, who was attacked while working at a Motel 6 in Clarkston, Washington. According to court documents, Henry was stabbed multiple times in the chest and face during the incident but survived the attack.

While Phyllis Krogman was acquitted, her husband, Thomas Krogman, was convicted for his role in the crime. A jury previously found him guilty of attempted first-degree murder and conspiracy to commit attempted first-degree murder for carrying out the stabbing.

On March 16, 2026, Thomas Krogman was sentenced to 39 years in prison. Prosecutors established that he drove approximately 13 hours from Wyoming to Washington to execute the attack on his brother-in-law.

Allegations of Orchestration

The prosecution’s case against Phyllis Krogman was based on the theory that she helped orchestrate the cross-state plot. Investigators alleged that she initiated the sequence of events through a telephone conversation with her brother roughly 36 hours before the stabbing took place.

During that call, authorities claimed Krogman asked Henry where he was living and working, and Henry informed her that he was staying and working at the Motel 6 in Clarkston.

Court documents indicate the conversation became accusatory when Krogman confronted Henry regarding allegations that he had sexually abused family members years earlier. According to an affidavit filed in the case, Henry denied those allegations during the call.

Following this exchange, Thomas Krogman traveled from Gillette to the motel in Washington, where he attacked Henry. Surveillance video was used during the proceedings to track Thomas Krogman’s journey between the two states.

Despite these allegations of coordination and the conviction of her husband, the Asotin County jury found insufficient evidence to convict Phyllis Krogman on the charges of conspiracy and attempted murder.
