Two more police face the sack after a black emergency worker was killed in her own home, nine months after the fatal shooting.
Breonna Taylor's death sparked a wave of protests in the US, after police shot and killed her during a botched raid on March 13.
Now two of the officers involved in the raid in Louisville, Kentucky, have been sent 'pre-termination' letters indicating they will be dismissed.
However, to date no police involved in the killing of the 26-year-old emergency medical technician have been charged in connection with her death despite widespread outrage.
Detective Myles Cosgrove, one of the officers who shot Taylor, and Detective Joshua Jaynes, who prepared the search warrant for the raid, said in a statement each had received notices of termination.
A third officer, Brett Hankison, was previously fired for his involvement in the tragic shooting.
In September, he was charged with three counts of wanton endangerment - a charge that carries a penalty of one to five years in prison.
But the charges against Hankinson relate to him firing shots into neighbouring homes and not killing Ms Taylor.
Police had forced their way into her apartment with a so-called "no knock" warrant, in relations to a drugs investigation but no narcotics were found in Ms Taylor's home.
Her boyfriend Kenneth Walker, who was with her when police burst into the home, fired once at what he said he believed were intruders.
Three police officers responded with 32 shots, six of which struck Ms Taylor, killing her.
Ms Taylor had previously dated a suspected drug seller but had severed ties with him, according to her family.
Her killing saw renewed attention over the summer as demonstrations against racism and police brutality spread across the US after the death in May of George Floyd.
Mr Floyd, a black man, was killed when a Minneapolis police officer knelt on his neck for nearly nine minutes.
