The elderly woman had a somewhat shocked look on her face, her mouth slightly open underneath an oxygen mask, as she sat buckled in the front passenger seat.

The car, parked on a sidewalk, was partially covered in a thin layer of snow. Temperatures in the small city of Hudson, N.Y., were in the single digits that Friday morning.

A citizen saw the woman and frantically called 911, according to news reports. The elderly woman had “frozen to death,” she told authorities.

Hudson police rushed to the location of the Subaru, CBS New York reported. Officers were unable to find the owner of the car, so they smashed the back passenger-side window — only to find that the woman was actually a life-size mannequin.

The mannequin was “extremely realistic,” CBS New York reported, citing a news release from the Hudson Police Department. It was wearing women’s clothing and glasses, and its face was covered in liver spots.

Police said that the mannequin was for CPR training and that the car’s owner is a sales manager for a company that manufactures medical training aids. Hudson Police Chief Edward Moore said the owner, who was not named, was “incredulous” that officers had broken his car window, according to CBS New York.

“Just to clear the record, all citizens of Hudson should be put on notice that if you park your locked vehicle on the street on a subzero night with a life-size realistic mannequin seated in it . . . we will break your window,” Moore said in a statement, according to CBS New York.

“I commend everyone who responded with the intentions of helping an elderly woman.”

Moore did not respond to a call and an email from The Washington Post on Sunday.

The owner “was not very happy with the police department for forcing entry into his car,” Sgt. Randy Clarke told ABC affiliate WTEN. “If it was a joke, it was a very poor, distasteful joke. If it was a matter of convenience for him — it was a station wagon — carry your mannequin a little bit better.”

Efforts to reach Clarke on Sunday were unsuccessful.
