Aggressive 'Hand-Raised' Deer Goes on Attack Spree in Colorado, Gores 56-Year-Old Man and Chases Child

An aggressive deer linked to multiple violent encounters with humans was shot dead in Colorado this week after goring a 56-year-old man and chasing a young child.

Officials from Colorado Parks and Wildlife said the animal had been wearing a fluorescent orange collar when it was spotted by multiple residents in the areas of Franktown and Elizabeth between November 10 to November 13, when the latest attacks were reported to police.

Officials confirmed the last two encounters took place near Tomichi Drive and Caribou Drive in Franktown within minutes of each other, CBS4 reported.

Due to the collar around its neck and its initially friendly demeanour, experts believe the deer, a two-year old buck, was hand-raised by humans before being set free into the wild. Prior to Wednesday, there were no reports about a collared deer roaming in the area.

That evening, a 56-year-old man identified as Jordan Winn had to receive hospital treatment after being gored on his arms and legs by the angry young deer.

He told CPW officers he and his wife saw the animal at around 4:50 p.m. on the other side of a fence on their property. The wife said the deer had touched its nose on her finger, before coming through, knocking her back and pinning her into the barbed wire enclosure, KDVR reported.

Winn said he sustained wounds from the buck's antlers while trying to help his wife. He said he was knocked down and dragged around the ground before breaking free. His wife fled inside to call 911 before coming back and distracting the deer by shooting it with a pellet gun. A Douglas County Sheriff's Office deputy who arrived at the scene "dispatched" the deer, the CPW said.

An investigation quickly found that it was not the only close encounter local residents had with the rampaging animal. Officials said a Facebook user had posted about the same deer attacking him the previous weekend while he was doing yard work on a property in Elizabeth.

The incident was not reported to the wildlife agency, authorities said.

The CPW said it was also made aware of another report that came in at roughly 4:45 p.m. on Wednesday, saying the collared deer chased a 10-year-old boy before a man used his car to prevent it from attacking. The aforementioned goring happened minutes later.

"Every indication we see points to this deer being raised by people, one from its collar and two from its behavior," CPW wildlife officer Casey Westbrook said in a statement posted online. "We suspect somebody was raising it and released it after they couldn't handle it anymore."

Westbrook added: "These are some of the dangers that come when you try to domesticate, or even just feed wildlife, which is a major issue we start to see this time of year.

"These animals learn to expect something from humans and when they don't get it, they become dangerous, and encounters like what we saw here can happen. Mix in the fact that deer are now in the breeding season, and this all contributed to something that could have been prevented."

Under law It is illegal to own or possess wildlife in Colorado. "The behavior of any wild animal can be unpredictable, and the behavior of wildlife that get domesticated can be demanding and aggressive," Westbrook warned. "If this was reported to CPW on Saturday instead of being posted on Facebook, we might have been able to prevent this... wild animals should stay wild."
