GARNER | A Garner woman was allegedly driving at 99 mph when she struck and killed a Belmond motorcyclist in June.

Shannon Gamble, 34, has been charged with felony homicide by vehicle and misdemeanor operating while under the influence.

According to court documents, the toxicology report of Gamble's blood showed her blood alcohol content to be .109 percent. The crash occurred about noon on June 18.


Gamble was driving a silver 2009 Chevrolet Impala southbound on Highway 69 near Klemme.

While travelling up a hill in a posted and marked "No Passing Zone," the Gamble was in the northbound lane passing another southbound vehicle.

While still in the northbound lane, at the top of the hill, the Gamble struck a northbound Harley Davidson motorcycle head-on.

Motorcycle driver Nathan Wadsley, 31, was pronounced dead at the scene, according to law enforcement. The criminal complaint states that Wadsley was killed on impact. The crash occurred near U.S. Highway 69 and County Road B-60.

“Investigation into the collision found the defendant was driving the Chevrolet Impala at 99mph at the time of collision, within a 55 mph zone,” the criminal complaint said

Gamble was life-flighted after the crash.


The Iowa State Patrol handled the investigation, Hancock County Sheriff Scott Dodd said, which can take several months when a collision involves a fatality.

"This is a fatal car-motorcycle incident ... it takes time to complete those investigations,” Dodd said.

Gamble’s initial appearance will be 9:45 a.m. Oct. 4 at the Hancock County Courthouse. She is held in the Cerro Gordo County Jail on a $25,000 bond.
