Problem:The prognosis for Michael Sanchez Jr. remains tenuous after the crash victim survived seven days in a thicket off a South San Jose freeway. 
  
 Relatives kept vigil Thursday over the 25-year-old San Jose man — on life support at a local hospital — as one of them told a television station she doesn’t understand why it took authorities so long to find him just yards from where he was last seen. 
  
 Sanchez, an Andrew Hill High School alum, was discovered unconscious Tuesday evening by detectives following up on a missing persons report, a week after the California Highway Patrol says it searched the same area near Hellyer County Park. 
  
 “If they did their search, they should have found my brother’s body,” Pricilla Sanchez told ABC 7. Sanchez said she wants answers from authorities. 
  
 CHP Lt. Les Bishop said he shares the family’s frustration but defended his agency given what they knew at the time of their May 8 search, which occurred two days before Michael Sanchez was reported missing. 
  
 “I’m upset about it too,” Bishop said. “Nobody feels good about what happened here.” 
  
 It was about 1:10 a.m. May 8, moments after Sanchez ended a phone call, when his 1991 tan Ford Ranger pickup veered off southbound Highway 101 and overturned in a triangular patch between the on- and off-ramps at Hellyer Avenue. 
  
 Bishop said a motorist who witnessed the crash stopped, called 911 and walked over to help, but stopped when he saw someone climb out of the upended truck and disappear into the woods. 
  
 Responding CHP officers did not find evidence someone was injured in the crash, Bishop said, and vehicle information pointed to an address in Visalia. An hourlong search aided by high-powered lights, local firefighters and the Sheriff’s Office turned up nothing, Bishop said, adding it wouldn’t have been unusual at that point for the agency to impound the vehicle and wait for its owner to contact them. 
  
 “We had no indicator that this driver was a missing person. With what we had to go on, we felt (the search) was thorough and complete,” Bishop said. “In hindsight, it didn’t work out that way, and we acknowledge that. I don’t have a good answer as to what happened or didn’t happen.” 
  
 On May 10, relatives reported him missing to San Jose police after he was a no-show at a funeral. 
  
 San Jose police spokesman Officer Jose Garcia said the report was sent to the investigations division Friday, but sat in that office until Monday, when detectives got their first look at the case. 
  
 Garcia said missing persons detectives typically don’t work weekends except for “at-risk situations” — cases involving children or people with medical or psychiatric conditions or who made suicidal statements. 
  
 Police investigators soon learned Sanchez’s truck was impounded last week. They went out to the crash site Tuesday afternoon looking for clues. Instead, they found Sanchez unresponsive but alive nearby beneath a canopy of trees that Garcia said shrouded him. ||||| KTVU.com 
  
 The doctor of a young man who was found alive one week after his truck went down an embankment in San Jose on Thursday said he was pleasantly surprised at the progress his patient has made. 
  
 25-year-old Michael Sanchez was found by police in San Jose’s sprawling Hellyer County Park in San Jose just off Highway 101 on Tuesday evening, a full week after he had rolled his vehicle in an accident. 
  
 On May 8th, Sanchez crashed his truck near Hellyer Avenue off Highway 101 and somehow ended up in thick brush nearby. The California Highway Patrol could not find him and stopped searching because, according to the CHP, witnesses said they saw the driver walk away. 
  
 Sanchez was found when San Jose police followed up on a missing person's report and linked him to the crashed vehicle. 
  
 Though Doctor Bruce Wilbur told KTVU he was pleased with his patient's progress, he said Sanchez will be at the hospital for quite a while before anyone will know for sure how much of a recovery he will make. 
  
 Wilbur said he has been monitoring the progress of Sanchez since he was brought to Regional Medical Center Tuesday night. 
  
 Sanchez's Facebook page shows profile pictures of a strong young man. Doctors said that his youth and physical condition were the main reasons he survived his ordeal. 
  
 Wilbur said Sanchez was initially in a coma and unresponsive, but has made significant progress in the past 48 hours. 
  
 "Initially, he was on a respirator and the respirator was completely responsible for his respiration, but now he is breathing spontaneously," said Wilbur. 
  
 Dr. Wilbur said he was not sure how Sanchez managed to walk away from the crash and then collapse. 
  
 "He did suffer some sort of blow to the head, said the doctor. The nature of that blow I [couldn’t say], would be speculation except to say that he had a blow to the head," said Wilbur. 
  
 When asked if he had a chance to talk to the family and what their reaction was, the doctor said they were realistic in their expectations of his survival. 
  
 "They had been so worried for eight days and they know -- all of us know -- that anybody who is out in the elements for eight days without any water has a very poor chance of surviving," said Wilbur. 
  
 Michael's father, who can be seen in photos on Sanchez’s Facebook page, came to the hospital but did not comment on his son's situation or on the crash and unsuccessful search. |||||
Solution:
A San Jose man is fighting for his life in a hospital after spending a week without food or water in a thicket close to where his pickup crashed. Police following up a missing persons report found Michael Sanchez, 25, lying unconscious just yards from where his vehicle veered off the highway and rolled over. The California Highway Patrol says a witness reported seeing a man climb out of the truck and walk away after the crash. A thorough search of the area was carried out immediately, but no one was found. "We were looking all over for this gentleman," a CHP spokesman tells the San Jose Mercury News. "We not only searched the immediate area and the brush, but we checked the shoulders on the freeway, the neighborhoods and the adjacent parks." Sanchez was in an area "secluded with shade and just completely blocked from all view from anywhere on the roadway," said a cop. Sanchez, who suffered a blow to the head, was rushed to a local hospital unresponsive and in a coma, but has been making good progress ever since, a doctor tells KTVU.
