LOUISVILLE, Ky. (WDRB) -- The state's high court upheld the firing of a former Louisville Metro Police officer who lied on the search warrant for Breonna Taylor's apartment.

Joshua Jaynes appealed his termination to the Kentucky Court of Appeals. Jaynes prepared the search warrant that led officers to Taylor's apartment in March of 2020.

Jaynes wrote in the search warrant affidavit, under oath, that Taylor's ex-boyfriend, Jamarcus Glover, was receiving packages at her apartment on Springfield Drive and said he confirmed the information through the U.S. postal inspector — one of the key justifications for the warrant.

In May 2020, a U.S. postal inspector in Louisville said Metro police did not use his office to verify that information.

Jaynes has admitted he never spoke to the postal inspector.

Through later proceedings, Jaynes also admitted he did not directly verify any information with a postal inspector. 

The Court of Appeals upheld his firing, specifically citing the false information he provided for the warrant.

Detective Brett Hankison, along with Mattingly and Detective Myles Cosgrove, with LMPD's Criminal Interdiction Division, burst into Taylor's Springfield Drive apartment around 1 a.m. March 13 to serve the search warrant. Taylor was inside the apartment with her boyfriend, Kenneth Walker.

Taylor, 26, was shot six times and died at the scene.

Walker thought they were being robbed, according to his attorney, and fired at officers when they rushed in, hitting Mattingly in the leg.

Jaynes also faces several federal charges for his actions. Justice Department prosecutors accused him of lying on the warrant and violating constitutional rights.

They also allege Jaynes attempted to cover it up through a conspiracy to falsify records and make false statements to federal investigators. 

The next hearing ahead of that federal trial is scheduled for February.
