Authorities say the suspect used an edged weapon in at least one of the killings Friday morning.
Police found the suspect and one victim at a science building on the Casper College campus, which was locked down as authorities assessed the situation. The other victim was found about 2 miles away.
Casper Police Chief Chris Walsh says the suspect wasn't believed to be a Casper College student, but it appears there was a relationship between him and the victims.
Walsh says there is no further threat to the community.
