Louisville police officer files suit against Breonna Taylor’s boyfriend

Mattingly's suit alleges assault and battery as well as emotional damages. "Walker did intentionally shoot Mattingly or acted recklessly in firing his pistol in the direction of the Police Officers who were serving a search warrant," states the text of the lawsuit.

According to NBC News, Mattingly was shot in the leg in the performance of his duties as a police officer during the raid on Taylor's apartment. The bullet that hit him came from a gun fired by Taylor's then boyfriend, Kenneth Walker.

This bullet was the first round of an exchange of gunfire that occurred between Walker, Mattingly and two other police officers, Myles Cosgrove and Brett Hankison.

The officers were serving a warrant as part of an ongoing narcotics investigation. Although the warrant issued was of the "no-knock" variety, the three policemen did not to execute it as such. Instead, they knocked and identified themselves as the police several times before forcing entry. That's when Walker's first shot came.

The following gunfight would leave Taylor dead, having been shot six times. Lamentably, the warrant was issued looking for a specific person who was neither Walker nor Taylor, but an ex-boyfriend of Taylor's, who had moved out since.

Mattingly's lawsuit alleges "severe trauma, mental anguish, and emotional distress" due to Walker's conduct. "Mattingly was shot and nearly killed by Kenneth Walker. He's entitled to, and should, use the legal process to seek a remedy for the injury that Walker has caused him," continues the lawsuit.

Walker has already filed a civil complaint against the Louisville police department and the city government. In an interview, Walker said that they had called out several times after hearing a bang at the door, but received no response. Walker claims he thought the police were criminals breaking in.

"It was dead silent. I'm a million percent sure that nobody identified themselves. If it was the police at the door and they just said 'we're the police,' me or Breonna didn't have a reason at all not to open the door and see what they wanted."

Neither Walker Mattingly nor Cosgrove are facing any criminal charges. Hankison has been indicted for wanton endangerment and has pleaded not guilty to charges.
