The Pennsylvania Game Commission is looking for the boaters who used a bow and arrows to illegally shoot and kill wildlife on the Susquehanna River.
A mallard duck and a snapping turtle killed near the Brunner Island power plant in York Haven had been shot with hooked arrows typically used for bowfishing.
"They were likely floating down the river, picking off whatever they could," Game Commission spokesman Travis Lau said of the poachers. "To see those animals shot and left to die is just a complete waste."
Officials believe the poachers were experienced bow anglers who launched their boat from Goldsboro.
Anyone with any information is urged to call the Game Commission at 610-926-3136.
