Today Clackamas County Sheriff's officials identified the gunman in the fatal mall shooting as Jacob Tyler Roberts, 22, of Portland.
The victims were identified as Cindy Anne Yule, 54, of northeast Portland; the other person who died was Steve Forsythe, 45, of West Linn. A 15 year old girl is in "serious" condition at OHSU.
Sheriff Craig Roberts: “At this time we don't understand the motive of this attack, except to say there's no apparent relationship between the suspect and his victims."
He was armed with an AR15 semi-automatic rifle, stolen earlier in the day from someone he knew. Police say they don't know how many rounds were fired, but say he was armed with several fully loaded magazines.
They've searched his house in Portland and his VW Jetta in the mall parking lot, but aren't releasing details of what those searches revealed.
