A motorcyclist who crashed into a Washington florist’s delivery van late last month died from his injuries.

Washington police said Cody Slaght, 23, Union, died Monday, Sept. 4, at Mercy Hospital St. Louis from injuries sustained in the Wednesday, Aug. 30 crash in Washington.

Slaght was injured in the crash that occurred at 11:09 a.m. at the Eighth and Stafford streets intersection. According to the Washington police preliminary crash report, he was driving a 1994 Suzuki Katana GSX 750 motorcycle headed west on Eighth Street.

Witnesses at the scene said the motorcycle was traveling at an excessive rate of speed and ran a stop sign. Slaght’s motorcycle struck a 2016 Ford Transit Connect van owned by Four Seasons Florist.

The van was heading southbound on Stafford Street. The driver of the van, Leroy See, 77, said he didn’t see any oncoming traffic when he attempted to drive through the intersection.

The motorcycle struck the driver’s side rear of the van. The impact caused the van to spin and ejected Slaght from his motorcycle.

Slaght was taken by ambulance to Mercy Hospital Washington and then flown to Mercy Hospital St. Louis by helicopter with serious injuries.

Police said Slaght was spotted by an officer traveling at a high rate of speed prior to the crash. An officer attempted to stop him for a traffic violation on Eighth Street just west of Jefferson Street at 11:08 a.m., but police said the  motorcycle accelerated at a high rate of speed continuing west on Eighth Street.

The officer immediately turned off his emergency lights and did not attempt to pursue the motorcycle. A few minutes later, the motorcyclist was involved in a crash with a 2016 Ford Transit Connect van.

The driver of the van sustained minor injuries, a cut on his arm, and declined transport by EMS.
