Although deer home invasions are not frequently reported to us, a wildlife expert told us that such incidents are fairly frequent.
Professor Gerald Hough of Rowan University stated, "They perceive a window or a screen door as a potential means of escape from whatever it is that they're being pursued by."
According to the wildlife biologist, deer may mistake darkness on the opposite side of the glass for an entrance and become imprisoned, as they did in this instance.
Hough stated, "The best thing you can generally do is call your local wildlife control because it's probably quite surprised and not used to being in a domestic property."
He advises you can try to guide the animal to an open door, just like Brian did, without necessarily grabbing it by the antlers.
When Brian last saw the deer, it crossed the street into a forested area and appeared to be unharmed. He hopes it remains there for a long time.
