A 21-year-old man was arrested Tuesday afternoon in Nevada in the investigation into the weekend killing of a University of Idaho student.
That's after police used telephone records from the victim's cell phone to track down the suspect.
John Joseph Delling, whose last known address was Antelope, California, was detained by police in Sparks at about 4pm.
David Robert Boss, a 21-year-old from Boise, was found dead early Saturday in the kitchen of his apartment near the University of Idaho campus.
He'd been shot twice in the head at close range.
Moscow Assistant Police Chief David Duke says a telephone registered to Delling, who knew Boss while the pair attended high school in Boise and later college in Moscow, made a phone call to the victim just after midnight last Saturday.
That was about the time Boss was believed to have been slain.
Moscow police worked with telephone company Sprint in order to trace Delling to Sparks.
Duke says, ``A motive hasn't been determined at this point,'' but adds that detectives from the Moscow Police Department are en route to northern Nevada to interview Delling.
Delling was a U of I student until 2005.
Boss was last seen alive about eight-thirty Friday night, and was thought to have died between midnight and 12:30am
