Brett Hankison, 44, claimed that Kenneth Walker, 27, told him that his late girlfriend Breonna Taylor had a 9 millimeter gun, which she fired on March 13, 2020. That day, Hankison and his former Louisville Metro Police Department colleagues Jonathan Mattingly, 47, and Myles Cosgrove, 42, raided her apartment in southwest Jefferson County in Kentucky, United States.

During a grand jury proceeding on September 23, 2020, Hankison was indicted on three counts of first-degree wanton endangerment for threatening the lives of Taylor’s neighbors. He, Mattingly and Cosgrove were not charged in her death.

On October 2, 2020, Kentucky’s attorney general Daniel Cameron released approximately 15 hours of audio from the grand jury proceeding. Among the recordings is Hankison’s interview with investigators after Taylor’s death in March 2020.

It was one of the interviews heard by the grand jury. In Hankison’s testimony, he quoted Walker as saying, “My girlfriend is dead in the apartment.”

“I mean, my mind was like, ‘Did he, did something already happen?'” Hankison recalled. “‘Did he kill his girlfriend?’ He said, ‘No, she was shooting with her 9, her 9 millimeter.’ He said she was the one that shot at us.”

However, Walker later on said that he was the one who opened fire because he thought they were being broken into. Mattingly was hit in the leg by a 9mm bullet.


According to a ballistics report by Kentucky State Police, which was obtained by USA Today, the 9mm bullet that hit and exited Mattingly was neither “identified nor eliminated as having been fired” from Walker’s gun “due to limited markings of comparative value.” Walker had a 9mm pistol while Hankison, Mattingly and Cosgrove were all carrying .40 caliber handguns, according to Cameron.

However, an LMPD record shows that Hankison had been issued a 9-mm weapon, according to Steve Romines, one of lawyers representing Walker. The former cop had been issued a 9 mm handgun in the past but “the notion that he fired a host of shots from his .40 caliber handgun then changed guns and shot one bullet from his 9 mm gun that struck Mattingly is a ridiculous argument not grounded in fact or reality,” the Louisville Courier Journal quoted his lawyer Kent Wicker as saying.
