HEGINS, Pa. – Two Schuylkill County students were injured by intruder on their school bus Tuesday – one with a busted lip and the other kicked in the leg.

“It was boom, glass flew all over, the deer was inside the bus, running all about in the aisle,” veteran bus driver Curtis Zemencik told WNEP.

Zemencik said he was picking up students Tuesday morning and was forced to stop by a herd of deer blocking the road. Seconds later, one jumped the hood and another came crashing through a window.

“I saw a herd of deer and two were coming across the road so I stopped the bus to let them pass when all of a sudden, a loud crash was heard and a large doe was literally on the lap of my front seat passenger,” Zemencik told The Citizen-Standard. “Everything just happened so quick, I believe we were all in shock.”

The deer smacked a boy in the lip, then took off down the aisle, kicking a girl in the leg, before Zemencik opened the door and it scampered away.

“It was pandemonium!” he told WBRE.

Zemencik, who has worked as a bus driver for 25 years, immediately rushed to help his injured passengers.

“We needed to clean up the blood,” he said. “I had him rinse his mouth out, checked his cut to make sure how big the cut was, and make sure he was okay and the others were okay.”

The students were then taken to a school nurse as the bus company went to work fixing the damage. The student who suffered the lip injury was later taken to the emergency room by his parents and missed the next day of school.

The bus, meanwhile, was littered with shattered glass, blood, mud and hair from the deer.

“Well, it wasn’t a quick fix. That glass was throughout the whole bus. It took my cousin five hours to clean it up,” Dan Bowman, of Bowman Brothers Busing Company, told WNEP.

Jerry Bowman, the other brother, told the Citizen-Standard “in all our years in the business, we have never had a deer leap through a window.

“It’s just one of those freak accidents that you can’t believe unless you see it,” he said.

Zemencik said the incident was a first for him, as well.

“I often thought of them running in front of me, slamming on the brakes, but never to go through a windshield and ending up inside with use,” he said.

Zemencik said the herd of deer were back as he made his rounds Wednesday morning, and students were understandably nervous.

“I went very, very slow, very cautiously,” he said. “You could hear the kids take deep breaths and think, ‘Oh, my gosh, here we go again,’” Zemencik said.

WNEP contacted district officials about the incident, but they declined to comment.
