Armed suspect in custody after standoff inside Snohomish County Courthouse; no injuries

An armed suspect was taken into custody after barricading himself inside the Snohomish County Courthouse, leading to a lockdown and a three-hour-long standoff. 

According to the Snohomish County Sheriff's Office (SCSO), the government campus at 3000 Rockefeller was on lockdown shortly before 1:00 p.m. Monday.

Dozens of officers from multiple agencies responded to reports of the armed man in the lobby. 

A witness told FOX 13 that he saw the man had a gun in his hands and another gun in his bag. The witness said it appeared he had on a bulletproof vest. 

A spokesperson for the SCSO confirmed that the suspect had "multiple" firearms but did not specify how many. 

The man became unruly with officers, which led to the lockdown. 

After negotiations, the suspect surrendered around 3:30 p.m. and was booked into the Snohomish County Jail.

No injuries were reported. 

The suspect has only been identified as a 32-year-old man from Woodinville. 

It's unclear why he went into the courthouse armed. Additional updates will be provided by the SCSO after the suspect has his initial court appearance on Tuesday.

Deputies say charges are pending. 

Other buildings on campus were also in lockdown and nearby streets were closed, but they have since re-opened. 

Everett Police, the Snohomish County Sheriff's Office, Washington State Patrol and the FBI all responded to the scene.
