UPDATE: Woman found shot Wednesday in downtown Indianapolis dies

A woman who was found shot in a pickup truck outside the City-County Building Wednesday afternoon died Friday.

20-year-old Azya Knowles' family had planned to take her off life support after donating her organs.

"She is brain dead. She is not coming back. She is a donor, so they are taking her organs from her to be donated to somebody else. She will be taken off her life support and I will never have my sister again," said Skylar Knowles, Azya's sister. "She is not even going to make it to her 21st birthday."

Skyler and her family want to know how and why her younger sister ended up shot and in front of Metro Police headquarters.

"I just want to know why he took her downtown to the City-County Building. Was she already dead when he took her down there? Did he shoot her? Does he know who shot her? Does he know who was shooting at them?" Skylar said.

The man who was driving the truck, identified as William Smith, has been arrested, but police are still working to determine who shot Azya Knowles.

Smith was arrested on a charge of unlawful Possession of a Firearm by a Serious Violent Felon (SVF). He is currently being held at the Arrestee Processing Center. 

The scene unfolded outside the city's courts and Indianapolis Metro Police headquarters. A bullet-riddled truck pulled up to the City-County Building around 1:30 pm. Police quickly shut down Market Street between Delaware and Alabama Streets. The driver in this case had to convince a police officer he was here to get help - something that didn't come easy since that police officer noticed the driver was armed with a gun.

Metro Police Officer Chris Wilburn had to think quickly on his feet. 

"He happened to have it in his hand. Obviously he was very excited when the officer initially encountered him," said Lt. Richard Little.

Witness Kadafie Love says the driver held the gun out of the truck's window as officers approached.

"He's like, 'I'm showing you my gun'," Love said.

Love recorded the incident on video.

"I seen the cop with his gun drawn and I see the guy with his hands out the window," Love said.

In Love's video, you can hear Smith say, "I'm trying to show you my gun," but an officer replies, "I don't want to see your (expletive) gun."

Once Officer Wilburn learned that the driver was trying to get help for his passenger - a woman suffering from gunshot wounds - the officer got back-up from a Marion County Sheriff's deputy.

"Start homicide. We got a dead body in the car. We got an individual in custody," an officer calls into his radio.

Paramedics rushed the woman to the hospital, where police say she remains in critical condition. (Police clarified an earlier report that she had passed away from her injuries to say that she remains in critical condition.)

"I ain't done nothing," Smith told police.

Love believes the man purposely turned into the City-County Building driveway when he saw a police officer there.

"Because it's a safe place to come," he said.

City employees and people doing business at the City-County Building watched and wondered what happened. Crime Lab workers processed the scene collecting evidence, including cigarettes seen in a plastic bag carried by the detective.

Detectives are also trying to figure out exactly who opened fire on the pick up truck.

"As you can see there are a number of holes in the windshield. The passenger side window is shot out," said Lt. Riddle.

Although police are thankful the shooting happened away from the always busy metro headquarters, they still hope to find out where and what started the deadly gunfire.

Love always has a camera ready. He shoots videos of aspiring musical acts for his start-up "Indy And Beyond."

But what he saw on Wednesday was way beyond the usual. But not hard to believe, he says.

"Actually, I can believe it, because there's a lot of incidents going on and the police are scared and we the community are scared," Love said.

Detectives continue to investigate Smith's involvement in the shooting incident, and the association between himself and the victim.

Detectives ask anyone with additional information about this incident to call Crime Stoppers of Central Indiana at (317) 262-TIPS (8477). Callers may also text "INDYCS" plus tip information to 274637 (CRIMES).
