PORTLAND, Ore. – On May 19, a young woman was stabbed at the MAX station near Lloyd Center. Her injuries were not life-threatening.

But just one week later and a few miles away, a horrific scene unfolded on another MAX train as two men were killed and another was injured in a stabbing. And now riders are concerned about safety on TriMet buses and trains.

Victims identified in MAX train stabbing

TriMet officials said Friday night their thoughts and prayers go out to the families of the victims, and that they are doing all they can to keep riders safe.

Spokeswoman Roberta Altstadt said TriMet is working closely with the Portland Police Bureau, transit police and other agencies to put more officers on trains and more security personnel on platforms.

And she applauded the efforts of employees and witnesses who helped bring to an end the violent rampage Friday night.

“We do want to thank the riders and our operator, who quickly called this in, tried to render aid,” she said. “And police who were able to capture this individual so quickly.”

Altstadt did not say whether the increased security would be permanent.
