Portland, Ore.'s TriMet issued a lifetime exclusion to Koryn Kraemer — the second lifetime ban in its agency’s history.

Kraemer, age 25, has been charged in the brutal attack on the Cleveland Avenue MAX Station platform, according to TriMet's news release. The attack occurred in the early morning hours of Jan. 3, 2023, when MAX service was not running. Kraemer was delivered the lifetime exclusion in jail, where he is being held without bail as he awaits prosecution on a charge of assault in the second degree.

Previously, only Jared Walter, a prolific sex offender, had been banned from TriMet property for life. That permanent exclusion took effect in April 2019.

The agency also announced Brianna Workman is now banned from the agency for the next five years. Workman, 32, is currently being held in jail without bail on charges of attempted assault in the first degree, along with other charges. TriMet security cameras captured Workman pushing a child onto the MAX tracks from a busy platform at the Gateway Transit Center on the evening of Dec. 26, 2022.

Dustin Rasmussen is excluded for five years, through Dec. 31, 2027. Rasmussen, age 22, admitted striking a Transit Security Officer with handlebars detached from a bike on March 24, 2022, at the Gateway Transit Center. The security officer was transported to the hospital. Rasmussen was charged with assault in the second degree and unlawful use of a weapon, along with other charges.

“TriMet remains committed to safety and security on our system, and we support a collaborative approach with state and local leaders to address the societal issues at the root of the incidents occurring on our system and in the communities we serve,” said Sam Desue Jr., TriMet GM. “While we rely on our district attorneys to prosecute crimes, we are taking steps within our authority to increase safety, which includes banning people from our system who attack others and potentially pose future threats to our riders and employees.”

TriMet first added its long-term exclusion policy to the TriMet Code in September 2017.

The policy and TriMet Code were further updated on Jan. 13, 2023, to authorize the GM to impose stiffer penalties for prohibited conduct on the transit system.
