State wildlife officials say a deer smashed into a western Pennsylvania elementary school, frightening students and teachers as it ran through hallways leaving a trail of blood.

The game commission says the animal broke its leg and had to be euthanized.

The Herald of Sharon reports the incident happened Wednesday morning at Monsignor Geno Monti School in Farrell, about 60 miles northwest of Pittsburgh.

Principal Alice Connelly says there was "blood all over" because the deer cut itself on the way into the school.

Lawrence Hergenroeder, a wildlife conservation officer for the game commission, says the deer likely saw its reflection in a glass door and darted toward it, smashing into the school.
