Topeka ? Flags will fly at half-staff across Kansas Friday to honor law enforcement officers killed in the line of duty.

Gov. Sam Brownback ordered the flags lowered as part of Kansas Law Enforcement Officers Memorial Day. A ceremony will be held at noon at the state Capitol in Topeka.

Brownback said in a statement that Kansans should take the opportunity to thank the families of people who gave their lives to protect the state.

The names of three officers who died in the line of duty in 2010 will be added to the 266 names already on the Law Enforcement Officers memorial. The three are Franklin County Sheriff’s Deputy Samuel A. Smith, Kansas Department of Wildlife and Parks ranger Luke Nihart and Santa Fe Railroad Special Officer George Greenstreet.
