The call came in at 9:03 a.m. Friday – an urgent description of a belligerent man with a gun.  

Seven minutes later, a second call followed, and after that, the normally peaceful intersection of Roe Street and Whetsel Avenue in Madisonville descended into chaos.  

 Cincinnati Police Officer Sonny Kim – a decorated and well-liked cop of 27 years – was dead. The father of three wasn't supposed to be on duty Friday, but he'd been tapped to work overtime in a city that's combating an uptick in crime.  
Also killed was 21-year-old suspect Trepierre Hummons, who police said made those 911 calls on himself while pretending to be a simple bystander. He wanted to die at an officer's hand, Police Chief Jeffrey Blackwell said, and had even texted friends about his plan.  

Hummons left what appears to be a farewell message on his public Facebook page that read: "I love every last one of y'all to whoever has been in my life ... you're the real mvp." The time stamp on the message was 8:55 a.m.  
While the events leading up to Kim and Hummons' deadly meeting Friday are still being sorted, the aftermath is clear: Kim became the first Cincinnati officer killed in the line of duty since 2000, and Hummons, the 29th civilian killed by an officer since then.  
The incident left a usually quiet neighborhood – one dotted with churches and filled with children who feel safe playing in their front yards – on edge.  
It left friends of Hummons confused and angry, yelling at officers at the scene and condemning police on social media.  
And it left a police department in mourning for a decorated officer that Blackwell called "one of our best."  
"We lost a brother today," Blackwell said. "Our hearts are broken."  

Hummons was no stranger to police. He spent three months in juvenile detention four years ago, when he was 17, after robbing a man's home at gunpoint and then stealing his car. His adult record included numerous traffic tickets and a disorderly conduct charge.  
Police said he also was a member of the Clutch Gang, which operates in Madisonville.  

His mother, though, just wanted to find her son. She went looking for him sometime before 9 a.m. and found him in the street, shortly before Kim arrived.  
As Hummons approached Kim, police say, Hummons' mother stood between the two men and told Kim, "I'll take him home." Then her son drew his gun. And Kim drew his.  

Hummons shot Kim multiple times and, soon after, wrestled away the officer's Smith & Wesson semi-automatic handgun, police say. He then began shooting at a probation officer who had stopped to assist on his way to work.  
Another police officer, Tom Sandmann, came under fire as soon as he arrived on the scene. While Hummons' mother tried to help the dying Kim in the street, her son turned Kim's gun on Sandmann and began firing, police say.  
Sandmann took cover behind his car, returned fire and fatally wounded Hummons
