While friends were commenting on his last Facebook post Friday — and some were reading text messages indicating his plan to commit suicide by cop — Trepierre Hummons called 911 then waited with a gun for police to arrive, Cincinnati police said.
When they did, he and 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.
The police, while armed, didn’t know what they’d walked into. That’s because when when the 21-year-old Hummons called the emergency operator, he didn’t hint at his plan.
Instead he 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.
“He’s walking around getting belligerent with a gun,” Hummons told the operator. 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. She ended the call and dispatched an officer.
Hummons dialed 911 again to make sure police were on their way, and he repeated his location. Moments later, the dispatcher repeated to an officer the description of the irate man with the gun.
“Copy, I’m in the area,” the officer answered her before bursting into shouts: “Shots fired! Shots fired!”
