High-speed chase ends in rollover near county line

George Williamson.

A Spirit Lake man was injured Sunday afternoon following a high-speed chase in southern Black Hawk County near the Grundy and Tama County borders.

George Marten Williamson, 32, was stopped by Black Hawk County Sheriff’s deputies around 2:15 p.m. on Oct. 3 for a speeding violation.

The initial traffic stop was made at the intersection of Highway 21 and Eagle Road/County Road D46 roughly eight miles west of La Porte City near Saint Mary of Mount Carmel Catholic Church.

Williamson was driving a black Dodge Ram pickup and had one male passenger with him at the time of the stop.

According to court documents, Williamson provided false information about his identity to the sheriff’s deputy during the stop. Once the deputy went back to his patrol vehicle to run checks on the information Williamson provided, Williamson took off in the pickup in an attempt to evade law enforcement.

Williamson then led law enforcement on a vehicle pursuit through rural county roads that lasted 25 minutes and reached speeds of 112 mph. The chase ended when Williamson lost control and rolled the truck onto its driver side in a ditch at the intersection of Grundy Road/M Avenue and Tama Road/280th Street, southeast of Reinbeck near the Grundy County line.

According to reports, the passenger in the truck exited without injury, while Williamson needed to be extracted from the wreckage with the help of fire and EMS crews.

He was airlifted to UnityPoint Health Allen Hospital in Waterloo with injuries and later released into police custody.

Williamson is being charged with eluding law enforcement with speeds over 25 mph, five stop sign violations and harassment of a public official for providing false identifying information to law enforcement.

It was later discovered that a warrant was out for Williamson’s arrest in Clay County for parole violation.

Assisting Black Hawk County Sheriff’s deputies in the pursuit were officers from Tama County and Grundy County.
