Louisville Police Sgt. Jonathan Mattingly is suing the boyfriend of Breonna Taylor for shooting him the night Taylor was killed on March 13.
Per legal documents obtained by People, Mattingly alleges he experienced "severe trauma, mental anguish and emotional distress" on the night he and fellow cops, Brett Hankison and Myles Cosgrove, executed a search warrant in a drug case connected to Taylor's ex-boyfriend, Jamarcus Glover.
At a press conference last month, Kentucky Attorney General Daniel Cameron said Taylor’s boyfriend Kenneth Walker, a licensed gun owner, “fired the shot that hit Sergeant Mattingly” and that “there’s no evidence to support that Sergeant Mattingly was hit by friendly fire from other officers.” Though Walker was initially charged with attempted murder of a police officer, those charges have since been dropped.
"Walker's conduct in shooting Mattingly is outrageous, intolerable and offends all accepted standards of decency and morality," the lawsuit read.
In a statement to People magazine on Friday, Mattingly's attorney Kent Wicker said his client “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."
However, Walker's attorney, Steve Romines, told CBS News that his client is "protected by law under KRS 503.085 and is immune from both criminal prosecution and civil liability as he was acting in self-defense in his own home."
"Even the most basic understanding of Kentucky's 'Stand Your Ground' law and the 'Castle Doctrine' evidences this fact. One would think that breaking into the apartment, executing his girlfriend, and framing him for a crime in an effort to cover up her murder would be enough for them,” Romines said. “Yet this baseless attempt to further victimize and harass Kenny indicates otherwise.”
In an interview with “CBS This Morning” earlier this month, Walker explained that he fired his gun because he and Taylor thought they were victims of a home invasion.
Despite what authorities say, Walker said he is “a million percent sure” police did not identify themselves that night.
"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 to see what they wanted," he added.
Days later, Mattingly gave an interview to ABC News where he insisted that he and the other officers announced themselves multiple times before entering Taylor’s apartment.
Though a grand jury declined to file murder charges in Taylor’s killing, they did charge now-former cop Hankison with three counts of wanton endangerment for firing into a nearby apartment. He has since pleaded not guilty.
