Here is complete story.
Deputies rushed to the scene on U.S. Highway 61 near Sperry, in Des Moines County, on Tuesday after receiving several reports about the possible jumper. They tried to talk the man down, but he didn't react to their commands, reports KWQC. One deputy then pulled out his binoculars and realized it was in fact a life-sized dummy.
"It was dark, they couldn't see," Sheriff Mike Johnstone told The Hawk Eye.
"They assumed it was someone jumping, but at some point they realized the person was not responding to their commands," he said.
"One of them pulled out their binoculars and realized it was a mannequin," he added.
The figure had been placed there by Brad Deery, the owner of a local car dealership. It sat on top of the sign which read: "From up here, I can see Deery of Burlington.” Deery took the dummy down on Friday.
"The sheriff didn't tell me to take it down, but when I heard about the 911 calls — I don't want to be tying up a line. I'm here to sell cars, not get people hurt," he told The Hawk Eye.
