The Whitley County Sheriff’s Office is warning people about a man knocking on doors claiming to be someone he is not. Sheriff Colan Harrell says deputies received their first complaint on January 18. A homeowner in Goldbug said a man knocked on his door and said he was delivering pizzas. When the homeowner came to the door, he told deputies the man holding a pizza box fled. According to deputies, the phony pizza delivery driver was in a black extended cab pick-up truck, in his 20s and wearing a plaid shirt. Police are trying to figure out the motive. Deputies say a second incident happened at a home on KY-1804, on the opposite end of the county. A man allegedly knocked on a person’s door claiming to be a deputy. Again, when the homeowner opened the door, the person took off. Police say it could be the same person, but they aren’t sure. The victim of the phony deputy says the man did not leave in a car and was only described as wearing a gray jacket and black pants. The Sheriff says all deputies will be in a clearly marked car and will be in uniform. They say the best thing is to not open the door and call 911 if you do not recognize the person knocking.
