There are sounds of rapid movement, the woman yelling "Get ready, (expletive)!" and the police radioing for help and repeatedly warning her to get back before five shots are fired.
Two officers who fatally shot a 30-year-old Seattle mother in her apartment have been identified.
On Thursday, Seattle police released Lyles' 911 call and a video recording from her hallway, showing the 24 hours leading up to the shooting.
Seattle mayor Ed Murray called the incident a tragedy and said it would be "fully investigated" by a federal monitoring team.
Even if he had brought the Taser, Anderson maintains in police transcripts it would not have been the "appropriate" tool for handling Lyles' abrupt and seemingly violent outburst toward the officers. That police report described Lyles as having "armed herself with a pair of extra long metal shears" and that she had been "threatening the officers". "... Our hearts go out to Charleena Lyles' family and certainly, most of all, her children", Whitcomb said in the stream.
"The officers immediately performed first aid", but fire medics arrived and determined she had died, the police department said in a statement Sunday afternoon.
Lyles had been in counseling, with and without her children, and she had obtained housing previous year after fighting homelessness for a decade, court records indicate.
Anderson said the conversation with Lyles began normally, involving what was missing in the apartment, before Lyles drew the knife as her "face changed completely".
Earlier this week the city released the dashcam audio from moments before the shooting, in which the officers noted that she had trouble with them before. Shots were heard in the audio.
The youngest three children - ages 11, 4 and 1 - were home when Lyles called police Sunday morning to report a burglary. "We expect safety. It was their responsibility to protect her and they didn't", James Bible, an attorney representing family members of Lyles, told CNN affiliate KIRO. "They could have used other (less lethal) force".
The shooting remains under investigation.
