Rossi died by hanging himself in his home at
Redstone Arsenal, Alabama, the home base of his impending three-star command, the U.S. Army Space and Missile Defense Command, which he was slated to take command of in two days. According to the
Army Times, Rossi's corpse was discovered by his wife upon returning home. Individuals who had worked with Rossi over the years paid tribute to their former superior and colleague, including former Fort Sill commander, retired Army general and close friend Lee Baxter, who praised Rossi as an "out front, very polished, professional leader" who "stepped up to be a true leader in the community". The Army also issued an official statement, commending Rossi as "a respected leader, valiant warrior and trusted friend who gave more than 33 years of service to this nation." With Rossi's death, David L. Mann's term as USASMDC commanding general was extended beyond statutory limits pending confirmation of another candidate as his successor.
James H. Dickinson was nominated and confirmed in December 2016 for promotion to lieutenant general, and relieved Mann on January 5, 2017.
Investigation The resulting investigation concluded that Rossi's death, ruled a suicide, was caused by feelings of inadequacy for his future three-star assignment, personal feelings of responsibility for the deaths of soldiers under his command, as well as sleep deprivation. Colleagues remarked to Army investigators that "death seemed to follow [Rossi]"; for example with 12 soldiers dying of various during his command of
Fort Sill, and driving down the
Highway of Death during the
Gulf War. Members of Rossi's staff on Fort Sill remarked that the general habitually carried photographs of the aforementioned soldiers in his wallet, four of whom had committed suicide. This constant exposure to and subsequent fixation on death was judged to have desensitized Rossi to the act of taking his own life. Additionally, Rossi expressed trepidation of his coming assignment to his wife only upon arrival at
Redstone Arsenal, days before he was due to assume command. Rossi remarked that "there was 'so much information' associated with the job that he didn't know or understand," fearing he would be "exposed as a fraud" for being unable to handle the diverse responsibilities at USASMDC. Such feelings of being intellectually inferior to the scope of his command were present since his tour as commander of Fort Sill, as according to former subordinates there, Rossi was uncomfortable "with the field artillery aspects of his job" and "spent countless hours" to appear competent and knowledgeable to those under his command. Rossi's suicide brought public attention to the problem of suicides in the American military, especially because he had been an ardent advocate for action against suicides. ==Awards and decorations==
