A Pennsylvania elementary school got an unexpected visitor that left students and teachers in shock!
A deer crashed through Monsignor Geno Monti School in Farrell, and left a very bloody trail through its hallways.
The deer was spotted at 7:30 and wildlife conservation officer, Lawrence Hergenroeder, believes the deer saw its reflection in a glass window and cut itself when it crashed through it.
The deer had to be put down because of severe blood loss.
