Authorities say a murder-suicide at a central Wyoming community college happened in a classroom while class was in session.

Casper Police Chief Walsh says a man wielding a sharp-edged weapon killed one person in a Casper neighborhood Friday morning before going to the nearby Casper College campus. The man entered a classroom in a science building and killed a teacher, then himself, in front of students. The other victim was found in a street about 2 miles away.

Police say the suspect used a sharp-edged weapon in at least one of the attacks, and no guns were involved.

The science center was evacuated and the campus was locked down following the attack that happened just before 9 a.m. Friday. The lock-down at the two-year school had ended by early afternoon.

Walsh says the suspect wasn't believed to be a Casper College student but he did know the victims. The police chief released no names but said the victims were a male and a female.

Casper's population is around 56,000, is about 250 miles northwest of Denver.
