Arrest made in killings of 4 Idaho college students, sources say

An arrest has been made in the brutal murders of four University of Idaho students, a law enforcement source and an attorney for one of the victims' families told CBS News Friday.

Shanon Gray, the family attorney for Kaylee Goncalves, said the arrest was made in Pennsylvania. A law enforcement source told CBS News the person of interest was taken into custody near Scranton.

Word of the arrest came more than six weeks after roommates Goncalves, Madison Mogen and Xana Kernodle were found stabbed to death in their home along with fellow student Ethan Chapin.
