Why are Ohio flags flying at half-staff? DeWine makes order in honor of slain officer

[This story has been updated to remove references to flags being flown at half-mast].

Flags in parts of Cleveland and Columbus are being flown at half-staff today in memory of Jacob Derbin, an Euclid police officer fatally shot in the line of duty on Saturday night.

Ohio Gov. Mike DeWine ordered the flags of the United States and the state of Ohio to be flown at half-staff at public buildings throughout Cuyahoga County and at the Ohio Statehouse, the Vern Riffe Center and the Rhodes State Office Tower in Columbus. The observance started Sunday and will continue until sunset on the day of Derbin's funeral.

The 23-year-old officer was called to a residence just before 10 p.m. on Saturday for a disturbance, where he was ambushed by the suspected shooter, 24-year-old Deshawn Anthony Vaughn, police reported.

Vaughn was found dead in an apartment the next day, U.S. Marshal Pete Elliot confirmed in a news conference Sunday night.

Ohio Attorney General Dave Yost said that this was Derbin's first year with the Euclid police.

"It is a cruel irony that a mother lost her son on Mother’s Day, and that this murder happened just as we prepare to solemnize our fallen during Police Memorial Week," Yost said.

Euclid Mayor Kirsten Holzheimer Gail encouraged the community to come together in support in a statement released Sunday.

"Let us unite in remembrance and gratitude for the sacrifice made, and pledge to uphold the values of compassion, resilience, and community spirit that this devastating loss so poignantly reminds us of," Holzheimer Gail stated.
