SEATTLE — The two Seattle police officers who shot and killed a pregnant woman inside her apartment had less lethal options and had been trained to deal with people showing signs of mental illness or other behavior crises.

The killing occurred as Seattle police are under federal oversight following a 2011 investigation that found officers were too quick to use force and all Seattle officers now receive training on how to better handle those with mental illness or abusing drugs. One of the officers who shot Lyles had been certified as a crisis intervention specialist.

Still, within minutes of arriving Sunday to take a burglary report, the officers drew their guns and shot 30-year-old Charleena Lyles with three of her four children inside her apartment.

Authorities say Lyles confronted the officers with two kitchen knives — less than two weeks after she had threatened officers with long metal shears when they responded to a domestic disturbance at her home.

Officials say the officers had at least one less-lethal way to handle the woman they knew had a previous encounter with law enforcement and had been having mental health issues.

Family members say they want to know why police didn’t use a non-lethal option.

At a vigil for Lyles outside her apartment building, family members called Lyles a good person and demanded justice.

Monika Williams, who said she was Lyles’ older sister, described Charleena as a woman who loved her kids and who liked to sing and dance.

Police and the mayor say the shooting will be investigated.
