A 39-year-old rock climber is facing a slate of attempted murder charges over an alleged plot to kill random people at a Smith Rock climbing event this weekend.

The Deschutes County Sheriff’s Office arrested Samson Zebturiah Garner on Thursday and took him to the county jail on several charges each of attempted murder of multiple victims, attempted first degree assault, attempted second degree assault and unlawful use of a weapon.

Law enforcement recovered a Beretta 9mm handgun, a Sig Sauer 9mm handgun and an AR-15 from Garner when he was arrested. The Deschutes County Sheriff’s Office seized those weapons under an extreme risk protection order during the arrest, meaning the courts will take those guns away for at least a year.
