The body of a 45-year-old cleaner has been found at a cannabis warehouse used by the 33-year old attacker, who went on a rampage on Tuesday, in which he threw hand grenades and fired shots in the Belgian city of Liege, killing four people, including himself. 125 others were also wounded in the violent incident. 　　The woman, who died from what appeared to be a bullet wound to the head, worked for the attacker, Nordine Amrani's neighbor. Two weapons and ammunitions were also recovered from his shed. 　　According to Belgian authorities, Amrani stood on the rooftop at the central Place St. Lambert and launched an assault on Christmas shoppers, killing a 15-year-old boy instantly. A 17-year-old boy and a 17-month-old baby later died in the hospital. Out of the 125 people wounded, 5 remain in critical condition. 　　Although the motive has not been confirmed, the police said that on the morning of the killings, he was called in for questioning in a sexual abuse case. Amrani had a history of run-ins with the law, in which he was previously jailed for drugs and arms offenses.
