WICHITA, Kan. (KAKE) - It was a chaotic scene near First and Washington downtown for hours over the weekend when family members say 18-year-old Lationna Johnson was shot in the neck after trying to break up a fight.

"She wound up getting shot and critically wounded. Within a short amount of time, due to the fine work that our men and women of this department did, we had a suspect identified. And we are actively searching for this suspect," said Lt. Mike Linnehan with the Wichita Police Department.

Linnehan says the suspect is 19-year-old La'Niah Banks. He says investigators were able to find her car, but she's still on the loose.

With more than 100 violent crimes already this year, according to the community crime map, Linnehan says it's time to rethink how they patrol the area.

"We assigned a lieutenant to be in charge of night operations. And the lieutenant is the old town supervisor who works Friday and Saturday nights down in Old Town. And what we did is we took groups of officers from each of the patrol bureaus, and we designated particular officers to be responding to Old Town Patrol. And the goal there was consistency," said Linnehan.

Linnehan says these designated officers will work with business owners and security guards to make sure everyone stays safe as downtown Wichita continues to grow.

"The overall hope is to curb the violence. So we want to make sure we stress that violence has never been tolerated in Wichita, and it never will be. And it certainly won't be tolerated in Old Town. And if somebody commits a crime of violence in Old Town, we will arrest you, and you will go to jail," he said.

WPD says if you see banks, you're asked to call 911 immediately. Police say she's considered armed and dangerous.
