CLAREMONT, Calif. — Officials say the body of a Pomona College associate professor who went missing on a solo hiking trip has been found in Kings Canyon National Park.

The Los Angeles Times reports that 50-year-old Alfred Kwok of Claremont was found Tuesday and his body recovered Wednesday from the upper southwest face of Deerhorn Mountain in the Sierra Nevada ( ).

Kwok’s cause of death is still under investigation. He was expected to have returned from the trip Sunday.

Pomona College says he grew up in Hong Kong and joined the faculty in 2000. He was an associate professor of physics and astronomy and was known by students and faculty for his love of the outdoors.

Kwok is survived by one brother and his parents, also of Claremont.
