The bureau's statement doesn't say whether the victims are injured or slain. The shooting also doesn't appear to fit the profile of a mass shooting. The police say "the suspect or suspects have left the area."
Rosemary Anderson is at 717 N Killingsworth Court, between N Albina and N Borthwick a block south of N Killingsworth. The bureau says its investigation's more than likely going to disrupt traffic. The school is an alternative high school, open since 1983, serving what can be a challenging, at-risk student population.
Parents have been asked to meet at Killingsworth Court and N Kerby. The bureau also says nearby Jefferson High School and Portland Community College are both on lockdown.
According to Rosemary Anderson's website, it has up to 190 students a year with a 90 percent graduation rate. The school is run by Portland Opportunities Industrialization Center, Inc.
"Our at-risk students have either been expelled or dropped out of public high school and many are homeless," the school's website says. "RAHS provides open-door year round access to the 'last chance' to complete a high school education, and is currently achieving a 90% graduation rate amongst students who enroll and attend classes."
We'll update with more details as they come in.

The word from media on the scene is that the shooting occurred outside the high school, and that all victims were alive when they were put into ambulances.

Portland Police Bureau spokesman Pete Simpson is drawing contrasts between today's attack and the many infamous school shootings that have played out across the country.
"This does not appear to fit that model,” Simpson told reporters. "It's an important distinction between somebody showing up like some of these active shooter scenes, versus someone that might be gang affiliated. There may be some sort of dispute we don’t know about."
