A weird case of weir sabotage

From the Alaska State Troopers:

Location: Anchor Point
Type: Assault, reckless endangerment, criminal mischief
On 6/8/10 at approximately 1400 hours, several employees from the Alaska Department and Fish and Game and the U.S. Fish and Wildlife Service were installing the weir on the Anchor River, just upstream from the Old Sterling Highway, when a large amount of debris floated down the river into them. The debris consisted of large trees, stumps and logs. Investigation revealed that Christopher Vigue, 46, of Anchor Point, intentionally placed the debris in the river in attempt to sabotage the weir installation. Vigue's actions placed seven people in risk of serious injury, and placed two people in fear that they would actually be injured by the debris. On approximately 9/3/10, Vigue was issued summonses to appear in court on charges of assault, reckless endangerment and criminal mischief.
