The Pennsylvania Game Commission is investigating four hunting accidents that injured five hunters today, the opening of the statewide firearm deer season. None of the injuries were fatal.

At about 9 a.m., a firearm dropped from a tree stand accidentally discharged, injuring a father and daughter hunting in Center Township, Indiana County. One was struck in the hand, the other was injured in the hand and leg.

In separate incidents, three hunters were injured in self-inflicted shooting accidents. In Derry Township, Westmoreland County, a hunter was shot in the ankle. A hunter was injured in Benton Township, Lackawanna County, and in Greenwood Township, Clearfield County, state police responded to an incident that occurred at 9:34 a.m.

Authorities were withholding the names of accident victims until their families can be notified.

The Allegheny County Health Department said 12 accidental shooting accidents, including three fatalities, occurred during last year's firearm deer season.
