A Leavenworth man involved in seven separate police chases has been sentenced to four years in prison.

29-year-old Franklin Donnie Stevens Dougherty was sentenced Friday.

Leavenworth County Attorney Todd Thompson said the chases spanned from December 2011 to March of this year. During one of them, Dougherty drove 100 mph through a 30 mph school zone in front of Leavenworth High School.

The last chase was on March 14. That’s when Leavenworth police chased Dougherty nearly to the Wyandotte County line. Kansas City, Kan., police picked up the pursuit, which continued into Overland Park.

Spike strips laid on the road shredded Dougherty’s tires, but he continued driving until he lost control and crashed.

Dougherty still faces charges in Johnson County.
