Murder in Washington state law constitutes the intentional killing, under circumstances defined by law, of people within or under the jurisdiction of the U.S. state of Washington.
In the state of Washington, a person may be convicted of first-degree murder when there is a premeditated intent to cause the death of another person. Murder in the first-degree is a class A felony in the state of Washington. [1] If a person is convicted of first-degree murder, they will not receive anything lower than life imprisonment with the possibility of parole. [2]
The offender can be charged with aggravated first-degree murder if he commits first-degree murder and have an aggravating circumstance, such as if the individual murders a public safety official, such as a police officer, firefighter, or paramedic. [3]
The United States Centers for Disease Control and Prevention reported that in the year 2020, the state had a murder rate well below the median for the entire country. [4]
The Washington data analysis of felony murder convictions indicates that the Washington statute is among the expansive predicate felonies for first-degree felony murders. The Kaiser and Molina data published in 2025 show that 37% limit felon murders to enumerated felonies. On the other hand, 13% of the states, including the state of Washington, apply expanded standards that allow second-degree felony murder judgments. [1]
An empirical study by Cohen, Levinson and Hioki in 2024 analyzed 3000 felony murder cases that occurred between 2000 and 2022 in various states of the United States. The article highlights that there are very profound racial disparities when it comes to the application of felony murder charges. In their analysis, they indicate that 48% of the people charged are black defendants. This data also suggests that 13% of these black defendants come from the 14% of the us population of the minority communities. This supports the broader discussion that there are disproportionate racial disparities when it comes to felony murder charges convictions. [2]
