A man found dead Sunday morning in a Downtown parking ramp was the third death in three days in the Madison area involving hypothermia during extremely cold temperatures.
A fourth person was rescued from the frigid cold on Monday when she was taken by a passerby to a Madison police station.
The death of Vance Perry, 57, of Covington, Georgia, followed the deaths of Jeffrey Bracey, 60, of Madison, and Alice McGaw, 84, of Sun Prairie.
Barry Irmen, director of operations for the Dane County Medical Examiner's Office, said Tuesday preliminary autopsy results showed hypothermia was a "likely contributor" in all three cases.
The final cause and manner of death was not disclosed pending additional study in each of the three deaths.
Perry's body was found Sunday morning in the State Street Capitol parking ramp after he walked away from a local hospital on Saturday.
Madison police went to an address in Madison after he left the hospital but were unable to find him.
An employee of the parking ramp, 214 N. Carroll St., found Perry's body Sunday morning.
"There were no signs of trauma, but the victim was not dressed for the frigid conditions," said police spokesman Joel DeSpain. "He was wearing a light jacket, a ball cap and no gloves."
Bracey was found outside in the 200 block of East Olin Avenue on Friday morning. He was taken to a local hospital where he died.
McGaw was found outside the Faith Gardens assisted living center in Sun Prairie also on Friday morning. She was a resident at Faith Gardens.
The state Department of Health Services, which oversees assisted living facilities, is investigating McGaw's death, spokeswoman Elizabeth Goodsitt said Tuesday.
On Monday, a 66-year-old town of Madison woman was found wandering and seemingly confused on a Downtown bike path, and was taken by a passerby to the Central District police station before taken to a hospital.
