TIMELINE | Step-by-step look at Breonna Taylor case, from her death to 4 officers facing federal charges |

LOUISVILLE, Ky. (WDRB) -- Four former and current Louisville Metro Police officers were charged Thursday with federal crimes in connection with the fatal raid on Breonna Taylor's home in 2020.

Ex-detectives Joshua Jaynes and Brett Hankison and current officers Kyle Meany and Kelly Goodlett face charges that include civil rights offenses, unlawful conspiracies, unconstitutional use of force and obstruction, Attorney General Merrick Garland said.

The action caps a federal investigation that looked at how police obtained the search warrant for Taylor's apartment, something a prior state investigation by Kentucky Attorney General Daniel Cameron's office did not pursue.
