The funeral is today in Mason City for one of the two Iowa National Guard members killed in a rollover accident last week in Johnston. Services will be held later this afternoon for Specialist Dustin Colby of Clear Lake, the 20-year-old member of the 11-33rd Transportation Company that was killed in an accident Friday near Camp Dodge in metro Des Moines. Colby’s driving partner, 30-year-old Sergeant Bruce Pollema of Hull, was also killed in the accident. Colby is the second member of the 11-33rd to die during the call-ups for Operation Iraqi Freedom. 23-year-old Specialist Josh Knowles of Sheffield died back in February when the truck he was in was hit by a mortar outside of Log Base Seitz near the Baghdad International Airport. Colby’s funeral service will take place at 3 o’clock this afternoon at the Iowa National Guard Armory in Mason City at 1160 19th Southwest, with burial at the Kensett Cemetery.
