On 24 March 1984, at approximately 8:55 am, he was shot five times at close range as he left for work. He was admitted to Hautepierre Hospital for the wounds he received. The attack was carried out by a gunman who walked up to his car and fired a 7.65-millimeter revolver, police said.[5] Police described the assailant who fired at Homme as a man in his 30s, of Asian or Mediterranean origin, wearing a beige overcoat. He fled the scene on a motorcycle. The Lebanese Armed Revolutionary Factions (LARF) claimed involvement in the attack.[6]
