Arkansas State University says three students, including two from Japan, are missing in a cave in northern Arkansas.
A university statement says the wife of 25-year-old student Casey Sherwood reported him missing Wednesday night, along with Japanese exchange students, 19-year-old Daiki Itoh and 18-year-old Daisuke Takagi.
Independence County Office of Emergency Management coordinator Glen Willis told KAIT-TV that two crews are searching for the students in Blowing Cave in Cushman, 110 miles north of Little Rock. Cave-mapping experts are assisting.
Willis and officials with the Independence County Sheriff's Office did not immediately return phone calls seeking comment.
Sherwood is from Jonesboro, Arkansas. Itoh is from Hiratsuka, Kanagawa, and Takagi is from Kawagoe Hi-who, Hyogo.
