Former officer Brett Hankison was sacked for violating procedure when he "blindly" shot 10 rounds into Taylor's apartment during the search, Fischer said.
Hankison is accused of "blindly" firing 10 shots into Taylor's apartment.
"I find your conduct a shock to the conscience", Schroeder said Friday in a letter detailing charges against Hankison.
The letter says he violated two standard operating procedures: obedience to rules and regulations and use of deadly force.
Both the mayor and Schroeder said that further questions about his termination can not be answered due to Kentucky state law.
Taylor, who was black, was shot eight times by officers who burst into her Louisville home using a no-knock warrant during a March 13 narcotics investigation. They instructed reporters to seek comment from Jefferson County Attorney Mike O'Connell. Mr. Cameron, the longer you wait to bring criminal charges against officers Jonathan Mattingly, Myles Cosgrove, and Brett Hankinson, the more trust erodes.
FBI agents were at Taylor's home Friday morning continuing their investigation, FBI Louisville announced on Twitter.
Sam Aguiar, an attorney for Taylor's family, said, "It's about time and this is the poster child of the dirtiest of dirty cops and the most unsafe of risky cops".
"It's about damn time". "This is an officer that's plagued our streets and made this city worse for over a dozen years".
Protests have been ongoing in Louisville for more than three weeks following Taylor's death. "It is right that he would be fired for killing Breonna and if justice had to be delayed we are thankful that it started on Juneteenth. It's undisputable evidence", said Christopher 2X, an anti-violence activist in Louisville. Taylor's boyfriend Kenneth Walker, who was home with her at the time of the raid, fired at officers in self-defense and was charged with attempted murder of a police officer.
"The three cops allegedly involved are yet be charged over her death, and in her second post on a new Twitter profile created this month, Jennifer wrote, "#SayHerName #BreonnaTaylor", above a powerful statement demanding Kentucky's Attorney General Daniel Cameron hold them to account.
