Melissa Horton was shot and killed in what has been described as a politically motivated assassination. She was a Democratic state representative in Minnesota. The shooting occurred early in the morning at her home, where her husband was also killed. The suspect, Vance Boelter, was disguised as a police officer and had a list of potential targets including other Democratic lawmakers. Authorities consider the shootings acts of targeted political violence. The suspect is accused of shooting Horton and her husband, as well as injuring another state senator and his wife in a related incident.
Additionally, there is a different incident involving a Melissa S. Horton in Tennessee, where she was fatally shot by deputies following a domestic violence incident. This case is unrelated to the Minnesota lawmaker's shooting and involves a separate investigation.
If the question specifically pertains to the well-known case of the Minnesota lawmaker, the reason for the shooting is politically motivated violence targeting Democratic lawmakers.
