Grand Forks Manslaughter Case Declared a Mistrial
Jurors have heard testimony from the accused and witnesses as they weigh whether Sean Tiessen acted in self-defense or committed manslaughter.
Justice Lindsay Lyster declared a mistrial on Thursday, August 27, in the Grand Forks manslaughter trial after the jury remained deadlocked following deliberations.
Tiessen, 47, faced one count of manslaughter in the death of Joshua Lockwood, 33, following an incident at a shared home on April 16, 2023.
During the 12-day trial, Tiessen testified he feared for his life, claiming Lockwood approached him with a hatchet while the jury reviewed audio from the shooting.
Lyster instructed the jury on Tuesday that any verdict required unanimity after Crown and defence counsel concluded closing submissions Monday.
Tiessen is scheduled to return to the Rossland Law Courts on September 8 for a scheduling appearance as the trial will begin again.
