As some students laughed in the videos, it was a serious matter to those in the office, who were stunned.
Police said the deer broke two of its legs. Animal control brought the severely injured animal outside, and say they had no choice but to put it down.
"I heard it broke its leg as it jumped through the window and there was blood everywhere," Chas Duro said.
A mess still there in the front hallway late Friday afternoon, prompting the school to bring in a professional cleanup crew to sanitize the area. After school activities, were canceled.
The superintendent's office said weekend activities will continue as scheduled.
A spokesman with the Massachusetts Division of Fisheries and Wildlife said, "This was a very rare and tragic situation where a deer was in the wrong place at the wrong time."
