The family of a missing Arizona State student is pleading for help after he vanished during a Grand Canyon trip just days before graduation.
Sandarsh Krishna, 26, was last heard from on April 27, when he told relatives he was traveling to Las Vegas with a stop at the South Rim. He was expected back in time for final exams and a job interview, but never returned.
“We haven’t had any success in finding him,” his sister-in-law, Pooja Shivananjappa, told Fox 10 Phoenix.
According to the National Park Service, Krishna’s last known location was along the Rim Trail off Hermit Road, between Bright Angel Lodge and Mohave Point, sometime between 4 p.m. on April 27 and 12 a.m. on April 28.

Investigators say Krishna, who had no known vehicle, may have been using a rideshare or taxi service. His cell phone data has not moved since the day he disappeared, according to his family.
“They’re doing the best they can, but unfortunately we do not have the exact location to see where he went missing,” Shivananjappa told the outlet.

Investigators also say Krishna was believed to be carrying a black backpack before he disappeared. That backpack was later turned in to hotel staff at Bright Angel Lodge early on April 28.
Rangers are now working to identify and speak with the individual who turned in the backpack, saying the person may have information that could help narrow the search area. Authorities emphasized the individual is not considered a suspect.
