"Breonna Taylor's entire family is heartbroken, devastated, and outraged. And confused, and bewildered, just like all of us, as to what did Kentucky Attorney General Daniel Cameron present to the grand jury?" Crump said.
Taylor, a 26-year-old African-American emergency medical technician, was shot and killed when three plainclothes officers broke down her door in March using a "no-knock" warrant to search for drugs.
Taylor's boyfriend said he believe the police were intruders and fired a gun at them. Police returned fire, shooting Taylor five times.
A grand jury this week decided the cops's use of force was justified.
Protesters took to the streets, outraged by the decision.
Crump on Friday demanded the state's attorney general share the minutes of the grand jury proceedings, "so we can know if there was anybody giving a voice to Breonna Taylor."
