The fatal stabbings of four students at the University of Idaho shook the college town of Moscow, a small community nestled in the rolling agricultural hills of the Palouse region that hadn’t seen a murder for five years.
The Nov. 13 slayings seemed to mystify police, adding to the tension in town as the weeks went by without a break in the case. Then on Friday a suspect was arrested more than 2,500 miles (4,000 kilometers) away in Pennsylvania.
