The public is encouraged to show support for an Ashland police officer who died on the job earlier this month by lining the streets Saturday along a motorcade route.

The procession for Officer Malcus Williams, which will include more than 100 public safety vehicles, is scheduled to begin at 9:30 a.m. at Southern Oregon University, according to a news release from Ashland police.

Williams, who was a 21-year veteran of the force, suffered a “major medical event” while responding to a March 2 domestic call. He went into medical distress after he arrived at the call in the 2000 block of Grizzly Drive and collapsed near the door of the home.

Two officers rendered aid while Ashland Fire & Rescue paramedics rushed to the area. Williams was transported to Providence Medford Medical Center, where he was pronounced dead at about 9 p.m.

The procession honoring Williams will proceed from South Mountain Avenue and turn left onto Siskiyou Boulevard to where the road turns into Lithia Way. The route continues on Lithia Way to the end of the downtown split at Helman Street, where the procession will turn left onto Church Street, followed by another left onto East Main Street.

Motorcade vehicles will then travel southeast on East Main Street, continuing where the thoroughfare becomes Siskiyou Boulevard. Vehicles will continue on Siskiyou Boulevard and end at Ashland High School, 298 S. Mountain Ave., where a celebration of life service will be held.

Residents should be prepared for road closures, traffic congestion and long delays along the route, especially along Siskiyou Boulevard and the downtown corridor, officials said. Motorists planning to drive in the area between 9 a.m. and 1 p.m. are encouraged to take an alternative route or delay plans until all events have ended.

Attendees are encouraged to walk, carpool or ride bicycles. Parking will be limited, though SOU has suspended parking fees in all its lots. Only lot 36 will not be available, as it will be used to house emergency vehicles.
