Martin Stickles, known as the “Kelso Killer,” remains a grim figure in the history of Cowlitz County, Washington. His crimes during the turn of the 20th century not only shocked a community but also highlighted the early challenges faced by the American justice system in dealing with mentally ill offenders.
Background and Early Life
Born in 1870 in Adams County, Iowa, Stickles relocated to Washington State with his family during his childhood. Leading a mostly isolated life, Stickles was known locally as a solitary fisherman, a profession that allowed him to live on the fringes of society.
The Crimes
Between 1899 and 1900, Stickles committed a series of murders that would brand him as a notorious serial killer. His victims, who were seemingly chosen at random, were brutally murdered, causing widespread panic and fear throughout Kelso and the surrounding areas.
Capture and Trial
Stickles was apprehended shortly after his final murder in 1900. The evidence against him was overwhelming, and he was quickly brought to trial. Despite the apparent signs of psychological instability, Stickles was deemed competent to stand trial. His trial was a pivotal moment in Washington’s legal history, as it raised significant questions about the treatment of the mentally ill in the criminal justice system.
Execution and Legacy
Convicted on multiple counts of murder, Stickles was sentenced to death and executed in 1901. His execution was one of the earliest in Washington State and contributed to the ongoing debate about capital punishment, especially in cases involving potential mental illness.
Psychological Analysis
Posthumous evaluations suggest that Stickles might have suffered from a severe form of mental illness, possibly schizophrenia, which was poorly understood at the time. His case underscores the historical context of mental health in the legal system and its impact on the handling of similar cases.
Impact on the Community and Legal System
The Stickles case had a profound impact on the local community, instilling a lasting fear and leading to changes in how local law enforcement handled crime. It also influenced legal practices regarding the mentally ill, highlighting the need for reforms in forensic psychiatry.

The story of Martin Stickles, the Kelso Killer, is a chilling reminder of the complex interplay between mental health and criminal behavior. His case continues to be studied by criminologists and historians as an important example of early 20th-century American criminal jurisprudence.
