Trepierre Hummons called 911 then waited with a gun for police to arrive, according to Cincinnati police. When they did, he shot and killed 48-year-old Officer Sonny Kim, a husband and father of three, police said.
Then he opened fire on two more officers, said Cincinnati Police Chief Jeffery Blackwell.
Not long before, he had made a Facebook post that seemed to indicate a plan to commit suicide by cop, according to CNN.
The police, while armed, didn’t know what they’d walked into. When when the 21-year-old Hummons called the emergency operator, he didn’t hint at his plan.
Earlier, he had pretended to be a concerned witness who’d seen a man acting erratically with a gun, according to 911 and dispatch tapes released by police. Then he gave a description of himself in a shaky voice. “Very early 20s … about like 5 (foot) 6 … he’s a little thick fellow.”
The operator took down his name and number. Hummons thanked her. The dispatcher notified a policeman in the area.
Hummons dialed 911 again to make sure police were on their way, and he repeated his location.
The dispatcher notified the policeman again. “Copy, I’m in the area,” the officer answered her before bursting into shouts: “Shots fired! Shots fired!”
Hummons wounded Kim multiple times in spite of the protective vest he wore, the police chief said. And when a probation officer arrived moments later, Hummons shot at him, too.
At some point, Hummons’ mother came out to the street.
“The suspect then returned to Police Officer Kim, who was lying wounded on the street and began to fight with him in an effort to take the officer’s firearm,” Police Chief Blackwell said.
Kim struggled as he bled, but couldn’t hang on to his weapon. A third officer, Tom Sandmann, arrived, and Hummons used Kim’s gun to fire at him. But Sandmann returned fire and wounded Hummons.
Both Hummons and Kim later died at a hospital, according to CNN.
