Flags in Wisconsin will fly at half-staff Monday in memory of Sen. Rick Gudex, Gov. Scott Walker said.

On Friday afternoon, Walker signed executive order 220, which orders that all U.S. and Wisconsin flags on government property be flown at half-staff from sunrise to sunset Monday.

Police said Gudex died Wednesday of a single gunshot wound to the chest.

A memorial service for Gudex will be held Monday.

His seat will remain vacant until January.
