LOUISVILLE, Ky. (LEX 18) — The family of an officer critically injured in a Louisville mass shooting has provided new updates on his condition.

Officer Nickolas Wilt of the Louisville Metro Police Department was shot in the head during a mass shooting at the Old National Bank in downtown Louisville on April 10. He has been in critical condition ever since.

In an update from Officer Wilt's family on Tuesday, they say he was transferred back to the University of Louisville Hospital. Officer Wilt was previously taken to the Jewish Hospital to receive specialized treatment for pneumonia.

They say he is still battling pneumonia but it's easier to manage now.

His family says Officer Wilt was also taken off of ECMO. According to Mayo Clinic, extracorporeal membrane oxygenation or ECMO is a method that "allows the blood to 'bypass' the heart and lungs, allowing these organs to rest and heal."

Officer Wilt's family says he had a 'good night' after being taken off of ECMO.

Officer Wilt remains in critical but stable condition.

LOUISVILLE, Ky. —

A Jefferson County Circuit Court judge dismissed charges against Kenneth Walker with prejudice on Monday morning, meaning the charges can't be brought up again.

Kenneth Walker is accused of shooting an officer when police busted down Breonna Taylor's apartment door during a drug raid almost a year ago.

Walker has maintained that he did not know the people at the door were officers.

He was charged with assault and attempted murder of a police officer after he opened fire during the raid, wounding Louisville Metro police Sgt. Jonathan Mattingly in the leg. Taylor was shot multiple times and died in the hallway.

The charges against Walker were later dropped but without prejudice, meaning they could be refiled if new information came to light.

Back in September, Walker and his attorney filed a lawsuit asking the court to declare him immune from criminal prosecution because of Kentucky's stand your ground law.

"I was raised by a good family. I am a legal gun owner, and I would never knowingly shoot a police officer," Walker said.

Commonwealth's Attorney Tom Wine's office said last Thursday he wanted to dismiss the charges with prejudice because state and local investigations "into this matter have concluded and no new information relevant to the charges against (Walker) in this matter has been brought to the Commonwealth's attention."

Monday's hearing lasted only a few minutes.
