Many dangers await migrants who attempt to cross the border from Mexico to the U.S. Hundreds of each year, faced with dehydration, hypothermia and drowning. Many more are missing along the route, separated from their group. In a StoryCorps interview from 2016, Ochoa talked about her work to make migrants' journey safer and to treat. them with dignity and humanity.
"If you fall and you are anxious to break an arm, or something like that, you can no longer keep up with the group, so they leave you behind," Ochoa said. "And if you can move and go there for a while, there's a lot of circling all the time. And I have stopped and walked to where they're circling to see: It's an animal that's circling or is it a person that's out there? "

Ochoa will ask migrants if they are experiencing any pain. If they responded affirmatively, the Samaritans will call for help – and sometimes that means calling U.S. Border Patrol
"That is the saddest thing. You want to help them, especially when they tell you," Well, just take me to town and I can have somebody come and get me from there and you can't do it, "Ochoa said. "You can not because you should have stopped by Border Patrol, you can end up in prison."
The organization says it does not transport migrants or operate on private land but frequently calls family members of migrants, aids money transfers, provides medical aid and supplies clothing, food and water
Volunteers have helped thousands of migrants in need of medical care, according to the Samaritans. The group has not been able to help every migrant in need.
A particular story continues to resonate with Ochoa after 17 years of service with the Samaritans.
"The one that always comes to my mind is searching for a 19-year-old young woman who was seven months pregnant, traveling with her husband, "Ochoa said. "She was tired and couldn't keep walking any longer, so the group left them behind."  Charts That Show What's Actually Happening Along The Southern Border “/>
"They looked for a shady spot where she could stay. The husband left her there to try and find help; found a Border Patrol officer and they went to look for her and she was gone. "
Despite four or five weekends of searching, the Samaritans were never able to locate Greece, the missing young woman.
Part of the reason Ochoa dedicates so much to assisting migrants is her personal connection to the journey.
"I come from an immigrant family," said Ochoa, a 70-year-old grandmother. "My mother herself crossed into the US when she was 12 years old. I have family on both sides of the border. And we can't generalize and say they're all, you know, bad people, because they're not."
"If we can save one life, our work is worth it," Ochoa said.
