The parents of a 2-year-old boy who was fatally mauled after falling into a wild African dog exhibit last fall have sued the Pittsburgh Zoo & PPG Aquarium, claiming officials had ample warning that parents routinely lifted children onto a rail overlooking the exhibit so they could see better.

Authorities are actively searching for a man who they said brought an assault rifle to the Westmoreland County business he works at early Thursday morning.

Jarome Iginla and James Neal each scored twice, Sidney Crosby, Chris Kunitz and Pascal Dupuis added goals, and Tomas Vokoun made 30 saves. Down 2-1 after the first period, the Penguins scored twice in a 40-second span early in the second and added four goals in the first 10 minutes in the third en route to a 7-3 victory.
