Louisa Swanson, age 10, female, was shot to death in her bed in the early hours of August 26, 2002, at the family's ranch near Augusta in Lewis and Clark County, Montana. Her 14-year-old brother, Swen, was killed in the same attack. Their mother, Jeanette Swanson, placed a 911 call after the shootings and remained at the scene for responding deputies. Prosecutors quickly filed two counts of deliberate homicide, and she was held in Helena without bail while under suicide watch.
In the months that followed, investigators and the court focused on the single suspect—Jeanette—whose case moved through Lewis and Clark County District Court. She later entered a guilty plea to the two homicides. Rather than prison, the judge committed her to the custody of the Montana Department of Public Health and Human Services for placement and treatment at Montana State Hospital for the term of her natural life.
Subsequent reporting and summaries of the case consistently identify Jeanette as the sole perpetrator; no other arrests or suspects have been named in connection with Louisa's death.
Public memorial listings mark Louisa's date of death as August 26, 2002, in Lewis and Clark County and note that her brother also died in the incident, echoing the official case history. The narrative that endures is stark: a quiet home in rural Montana, two children lost in their sleep, and a mother whose responsibility for the killings has been established in court and resolved with a lifetime commitment to a state hospital.
