Cincinnati Police Officer Sonny Kim was called to the scene of a man "walking around, getting belligerent with a gun" on the morning of June 19, 2015.
It turned out he'd been purposely lured to the corner of Whetsel Avenue and Roe Street, where TrePierre Hummons, 21, shot and killed him. Hummons was shot and killed by Officer Tom Sandmann in a gun fight.
The community immediately took to Twitter to mourn Kim and to remember the how he dedicated his life to the city of Cincinnati.
Kim's son, Tim Kim, wrote a heartfelt post for his dad on Instagram the day after his death.
"I'll miss your random texts just to tell me how proud of me you were and how much you love me, and most of all I'll miss you coming home from work every night and giving you a hug and just feeling safe and comfort around you," he wrote.
There are no public memorials planned for this weekend. Kim was remembered in recent weeks in several ceremonies from Cincinnati to Washington DC.
On Friday, his grave was marked with flags, visitation stones and a pin saying "I am loved." Kim's family has asked for privacy.
“They’re a very strong family, very much support from their family and friends," Cincinnati Police spokesman Lt. Steve Saunders said. "And it’s a difficult time, because you’re remembering what happened just a year ago.”
Anyone wishing to pay tribute can visit the Cincinnati Police Memorial across from District 1 headquarters on Ezzard Charles Drive, Saunders said.
