Georgia Gov. Nathan Deal has ordered the United States and Georgia flags be flown at half-staff through Friday to honor those affected by the Las Vegas mass shooting.

"With heavy hearts, we mourn those killed or injured in the heinous Las Vegas attack," Deal said in a Facebook post. "Sandra and I are praying for the victims, their loved ones, concertgoers, first responders and the people of Nevada."

Earlier this week, the governor ordered flags on state buildings and grounds be flown at half-staff in honor of Polk Co. Police Department Detective Kristen Hearne.

Hearne was killed in the line of duty on Friday.
