Galstyan was shot and killed outside of his home in Yerevan on December 19, 1994. His brother, who was with him at the time of the murder, chased after the assailants but was unable to catch them. Various theories exist about who ordered Galstyan's murder. Many speculated that Vano Siradeghyan had ordered the murder, while in 1996, Defense Minister Vazgen Sargsyan argued that the murder was the work of the "Dro" group, an alleged secret terrorist group within the Armenian Revolutionary Federation, with the intention of causing further hostility between the former Karabakh Committee members in power and those in opposition.
