Seattle police shot and killed Charleena Lyles, 30, while responding to a burglary call Sunday. Police said Lyles, who was a mother of three with a baby on the way, confronted them with a knife. (Published Monday, June 19, 2017)

The initial conversation between a pregnant woman and two Seattle police officers seemed polite, professional and calm. She let them into her apartment. They asked her about the video game console she was reporting stolen.

But a confrontation quickly erupted. A police audio recording of officers shouting "get back!" and the woman saying "do it! do it!" are among the few clues about what went wrong before she was shot and killed on Sunday.

Authorities said Charleena Lyles, 30, confronted the officers with aknife — a move that came less than two weeks after she had threatened officers with long metal shears after they responded to a domestic disturbance at her home.

On Sunday, near the beginning of the roughly four-minute police audio recording and before they reach the apartment, the officers discussed a "safety caution" about the address stemming from the previous law enforcement interaction with the woman.

The officers talk about the woman previously waving large metal shears and trying to prevent officers from leaving her apartment, and making "weird statements" about her and her daughter turning into wolves.

Seattle Municipal Court records show that Lyles was arrested June 5 and booked into King County Jail. She pleaded not guilty to two counts of harassment and obstructing a police officer.
