Prosecutors are working to permanently dismiss charges against Breonna Taylor's boyfriend Kenneth Walker

• Prosecutors have filed a motion asking for charges against Kenneth Walker to be permanently dropped.
• Walker was at home with Breonna Taylor when she was killed during a police raid in March 2020.
• He was initially charged assault and attempted murder of a police officer.

Prosecutors in Kentucky are moving to permanently dismiss charges brought against Breonna Taylor's boyfriend, Kenneth Walker.

Jefferson Commonwealth's Attorney's Office is filing the request for charges to be dropped, and a judge will make a final decision on March 8, CBS News reported.

If the charges are dropped, Walker will be unable to be recharged.

Walker was initially arrested and charged with assault and attempted murder of a police officer following the raid in which Taylor was killed.

As police burst into Taylor's apartment shortly before 1 a.m. on March 13, 2020, Walker shot Louisville Metro Police Sergeant Jonathan Mattingly in the thigh.

Walker has said he didn't know that it was police entering the home. He said he didn't hear police announce themselves, and instead thought intruders were trying to break in.

Police entered Taylor's home on a "no-knock" warrant and fired shots that killed Taylor. Police said they did announce themselves and started shooting after Walker shot at them.

The charges were later dismissed without prejudice in May, meaning he could face the same charges again.

Walker filed a lawsuit over the arrest in September, and in October Mattlingly filed a lawsuit against him, citing emotional distress, assault, and battery.

In a motion filed Thursday, prosecutors said investigations into Walker's arrest had concluded, and "no new information relevant to the charges against (Walker) in this matter has been brought to the Commonwealth's attention," according to CBS News.

Walker's lawyer, Steve Romines, did not immediately respond to Insider's request for comment, but he told CBS News that Walker was "relieved" by the motion.

"After the worst year of [Walker's] life, prosecutors have finally acknowledged that he did nothing wrong and acted in self-defense," Romines told CBS News. "He looks forward to continuing the fight to hold the real wrongdoers accountable for the harm that they've caused."
