MOUNT LEBANON, Pa. (AP) — A western Pennsylvania community's effort to make roads safer by thinning out the local deer herd has been scrapped because of problems ranging from ineffective bullets to vandalism.

Officials in Mount Lebanon, near Pittsburgh, announced the action on the municipal website Friday.

The Pittsburgh Tribune-Review says officials agreed to pay a contractor $500 a head in the hope of culling 150 deer to reduce the number of vehicle collisions. But since the program started March 10, only six deer had been captured and euthanized.

Documents that the newspaper obtained through a Right-to-Know request revealed that the contractor initially used quieter, subsonic bullets slower than the speed of sound. But it took 11 bullets to kill three deer. Vandals also damaged some equipment and weather conditions were not ideal.
