Suspect charged with attempted murder following March 18 shooting in NE Portland

Today, Multnomah County District Attorney Rod Underhill announced the filing of a three-count charging document against 32-year-old Marshawn Seamster for attempting to murder someone on March 18, 2020 in northeast Portland.

Seamster is charged with one count of attempted murder in the second degree, one count of attempted assault in the first degree and one count of unlawful use of a weapon.

This investigation started on March 18, 2020 at approximately 2 p.m. when Portland Police responded to a shooting near the intersection of Northeast Alberta Street and Northeast Martin Luther King Jr. Boulevard.

According to court documents, officers learned that there was an argument near the intersection of Northeast 9th Avenue near Northeast Alberta Street that occurred before the shooting.  

Some of the individuals involved in that argument left the area and drove westbound on Northeast Alberta toward Northeast Martin Luther King Jr. Boulevard.

While in the area, multiple witnesses reported hearing several gunshots.

According to court documents, officers with the Portland Police Bureau’s Gun Violence Reduction Team responded and located evidence of gunfire in the street and near the sidewalk. Officers also located a bullet strike to an occupied vehicle.

During their investigation, law enforcement determined Seamster to be the shooter, according to court documents.

After the shooting, Seamster got inside a separate vehicle and left the area, according to court documents.

On April 28, 2020, officers located and arrested Seamster at 3 p.m. in the area of Northeast Martin Luther King Jr. Boulevard and Northeast Cook Street.

This case is being investigated by the Portland Police Bureau’s Gun Violence Response Team.

Like in all criminal and civil matters, electronic copies of court documents, which are not subject to a protective order, are available to the public through the Oregon eCourt Information (OECI) system.

No additional information can be released by the Multnomah County District Attorney’s Office at this time pursuant to the Oregon Rules of Professional Conduct.

A charging document is only an accusation of a crime. Seamster is innocent unless and until proven guilty.

The Multnomah County District Attorney’s Office works closely with the City of Portland’s Office of Youth Violence Prevention and attends the bi-weekly Community Peace Collaborative meeting, which is a coalition of law enforcement, service providers and community members who are focused on encouraging people to take a stand against gun violence.
