The family of an Arizona State University student who vanished from the Grand Canyon just one week before he was set to graduate with his master’s degree are pleading for help as they look to speak with the man who found his backpack.

Sandrash Krishna, 26, told relatives on April 27 he was planning to stop at Grand Canyon’s South rim on his way to Las Vegas, but had planned to be back in time for final exams and his graduation on May 9, Fox News reports.

Tragically, he has not been heard from since, leaving loved ones desperately searching for answers.

His family has visited the South Rim multiple times over the past week, relying on cellphone tower data that shows Krishna’s last known location was between the Bright Angel Lodge and Mohave Point on the day of his disappearance.

His cell phone data has not moved ever since, leaving Krishna’s family scouring the area ‘two to three times already, looking for him,’ his sister-in-law Pooja Shivananjappa told AZFamily.

‘We obviously don’t want to give up, so we have taken our binoculars, we have walked the trail, we have done our own research.’

The family has even hired their own private investigator to help find Krishna, as his brother, Adarsh Krishna, said they ‘don’t want to believe he’s hurt’ and still have hope ‘that he’s somewhere out there.

‘But again, we need proper closure. We don’t know exactly what happened to him,’ Adarsh told KPNX, adding that his brother is ‘not the kind of kid who would hurt himself.’

Krishna had moved to Arizona from India in 2024 to pursue a master’s degree in computer science at Arizona State University.

His loved ones describe him as bright, kind and deeply family-oriented.

‘He has a helping hand,’ Shivananjappa said. ‘As I said, he has the heart of a kid, and we terribly miss him.’

Family members and park officials are now looking to speak with a good Samaritan who brought Krishna’s backpack to the Bright Angel Lodge lost and found at around 7am on April 27.

The man did not leave his name or indicate where he found the backpack, but authorities stress they do not believe he is a suspect in Krishna’s disappearance.

Authorities are instead looking to speak with him to get more details about where and how he found the backpack, in hopes that he could provide them with more details about what led up to Krishna’s disappearance.

‘This is the whole reason why we are calling, and we are reaching out to everybody to find the person who returned the backpack,’ Shivananjappa said.

‘This is a main piece of evidence as of now. If we can get to know the exact location of the backpack, we can focus on searching that specific area.’
