TACOMA, Wash. - Despite the freezing temperatures, thousands of people -- officers and civilians-- will take part today in the procession or gather along the route to the Tacoma Dome to pay their respects to four fallen officers.
FBI Director Robert Mueller will be among the thousands honoring the four Lakewood officers gunned down in a coffee shop last month.
The caskets of Sgt. Mark Renninger and Officers Ronald Owens, Tina Griswold and Greg Richards will be taken from McChord Air Force Base to the Tacoma Dome for today's memorial service. The procession will stretch for 10 miles for the largest memorial in state history.
Today's procession will make just one stop at the Lakewood Police Department, which is now awash in flowers and notes. It's here that the families of the slain officers will join as many as 3,000 police cars for the 10-mile procession.
The procession will begin at 10:00 a.m. at McChord Air Force Base, then wind through Lakewood, passing by the police station, winding up South Tacoma Way, and then ending at the Tacoma Dome where some 20,000 people will gather for the service.
The procession will be comprised of law enforcement officers who've come from near and far, including an entire plane load of more than 100 officers who arrived at SeaTac Airport Monday night from Boston.
Some out-of-towners are being hosted for free at a bed and breakfast run by an Auburn police officer and his family.
You want to be able to provide something for the families or the fellow officers, said the officer.
So do civilians, who have lined the procession route with signs of condolence, and local businesses who are donating everything from food and money to free coffee for the people planning to stand out in today's bitter cold simply to show their respects and share their grief.
Although the memorial is open to the public, there's little chance there will be room to get into the Tacoma Dome because so many officers are coming from around the nation. So there are now four overflow locations where the public can watch the service: at Pacific Lutheran University in the Olson Auditorium, the Christian Faith Center in Federal Way, The William Philips Hall on the University of Washington Tacoma campus and at Tacoma Champions Centre.
Today's procession and memorial service will also impact bus service in the area. Pierce Transit warns riders to expect major disruptions between 10 a.m. and 1 p.m. They are planning to reroute buses around the procession. Riders should expect significant delays, especially in the Tacoma Dome area, where the memorial takes place.
