INITIAL POST: Police closed Pacific Avenue in downtown Tacoma on Wednesday between South 25th and 26th streets as explosive experts investigate a suitcase found there, Tacoma police spokeswoman Loretta Cool said just before 4 p.m.
A passerby called police about 2:45 p.m. to report the large suitcase by the Sounder Train trestle there, Cool said.
The department's Explosive Ordnance Disposal team would likely use a water canon to disturb the suitcase to make sure it's safe, she said.
Buses and trains will be kept out of the area until police have finished investigating, she said.
