BYU student Yifeng Xu has been missing since Sunday, Nov 8.
A BYU student reported missing on Thursday was found later that evening on the BYU campus and has been taken to the hospital for evaluation, according to the Provo Police Department Facebook page.
University Police sent a campus-wide notice to faculty and staff Thursday evening asking for help locating Yifeng Xu, who also goes by Ephraim. The last time he was seen on campus was Sunday, Nov. 8.
Provo police said he was 'in a crisis... and suffers from some undiagnosed mental difficulties.'
On Xu's Facebook page, he says he attended Timpview High School. Kate Neish, Xu's old high school friend, said that he is studying math and computer science.
