( CNN ) -- Doctors will amputate the feet of a Colorado woman who was missing for five days before being found in her wrecked car just off a scenic highway , a family spokesman said Monday . Kristin Hopkins is in critical but stable condition at St. Anthony Hospital in Lakewood , Brian Willie said , reading a statement from the Hopkins family . `` Doctors were not able to save her feet due to the severity of her injuries , '' he told reporters , adding the amputations would be done Monday afternoon . Hopkins , a 43-year-old single mother of four , was reported missing on April 29 . She was found May 4 , still in her car , about 140 feet from U.S. 285 just north of Fairplay , the Park County Sheriff 's Office said . The Hopkins ' family statement thanked a man who found Hopkins in her car and drove to the sheriff 's office to report finding a car with a possible body inside . The man was not identified by authorities , who said he slipped out of the sheriff 's office after reporting the accident . A firefighter who treated Hopkins at the scene said it appeared she had written notes on the white portions of a red and white umbrella and was trying to use it to signal passersby on the highway . Lt. Jim Cravener , a firefighter with the North-West Fire Protection District in Park County , said , `` ( The notes ) were hard to make it out . One of them appeared to say 'Please help doors wo n't open . ' Another one ( said ) 'Please help , bleeding , need a doctor ' and another one said , 'Six days , no food , no water , please help . ' '' Cravener said Hopkins was `` really severely dehydrated . '' The man who spotted the car had stopped to take photos at the top of a pass near a sharp curve , Cravener said . `` He ventured off the highway a little bit , found the vehicle , and walked down to it , '' the firefighter said . `` The person thought they found a body . '' Cravener and another firefighter were surprised to discover Hopkins alive . The car was upside down in a heavily wooded and steep area . As the other firefighter went to break a window , Hopkins put her hand on the glass . Hopkins went in and out of consciousness , Cravener said . `` She said she crashed at night , '' he said . `` We assumed she crashed the night before , but it turned out it had been several days . '' The family asked for privacy during Hopkins ' recovery . `` While we are hopeful for her prognosis , Kristin was seriously injured with multiple internal and external injuries , '' Willie said . Hopkins lives in Highlands Ranch , about 90 minutes away from the accident scene . Trapped and dying in desert , man leaves behind love notes and questions .
