On the evening of June 3, 2026, 40-year-old Mark Thomas Tierney was found dead from a gunshot wound in the 87000 block of Huston Road in Veneta, Oregon. Lane County Sheriff’s Office deputies arrived after a report of a shooting and discovered Tierney deceased at the scene.

Within hours detectives arrested a family member, 63-year-old Martin Grant Tierney, and he was booked into the Lane County Jail on second-degree murder and unlawful use of a weapon. The sheriff’s office said all involved individuals had been identified and there was no ongoing threat, but the investigation remained active.

On June 12, 2026, the Lane County District Attorney’s Office moved to dismiss the charges against Martin Tierney without prejudice, citing new information that required further investigation. The nature of that information has not been disclosed, no other suspects have been named, and the case remains open.

Does anyone in the Veneta area have information about Mark Tierney or the events of June 3 that could help investigators?
