A lone gunman brought carnage to the Belgian city of Liege on Tuesday, spraying bullets at Christmas shoppers and hurling a grenade at people waiting for a bus, killing three people including a girl of 17 months before shooting himself dead.
On Wednesday, Belgian authorities say they found the body of a cleaning woman in the home of the attacker.
The attack, in which another 125 people were wounded, paralyzed the center of Belgiums fifth city, with workers trapped in offices as police sealed off the area, helicopters circled, and ambulances poured in from as far away as the Netherlands.
The man's motive was unclear but Belgian officials said there was no indication it was an act of terrorism.
Witnesses said 33-year-old Nordine Amrani had begun his rampage at about 12:30 p.m. near a bus stop at Place Saint Lambert, site of Liege's bustling Christmas market and its main courthouse. Shoppers scattered to flee the bullets.
Amrani was freed from jail about a year ago after a conviction for possessing weapons and drug offences.
Justice officials said Amrani had been summoned to answer police questions that morning on an undisclosed matter, but never turned up.
One witness told RTBF radio: "He had a bag. He got a grenade out of his bag. He threw the grenade at the bus stop.
"Then he had a Kalashnikov (rifle). He shot in all directions. Then everyone ran to try to save themselves. Then he got a revolver out and put a bullet in his head."
Police said the dead were two boys of 15 and 17, and a toddler of just 17 months whom hospital doctors fought for hours to save.
Liege's mayor, Willy Demeyer, said the two boys had been taking school exams nearby just before the attack.
By evening, Place Saint Lambert, whose Christmas market of around 200 stalls attracts over 1.5 million visitors each year, was still sealed off, covered with shattered glass and pools of blood, and there was still no indication of Amrani's motive.
At his most recent address, an apartment block near the scene of the attack, Johan Buron said he had been astonished to learn what his neighbour had done.
"He was calm, every time I met him in the corridor he was very friendly and said 'Hi'," he told Reuters. "If my memory serves me right, he was a welder."
Amrani was convicted in 2008 for illegal possession of arms and for growing a huge field of cannabis. "He has no history of terrorist acts," prosecutor Daniele Reynders told a news conference in Liege.
A spokesman for Belgium's crisis response centre also said there was no indication that it had been a terrorist attack. It was not clear whether Amrani was Belgian.
Prosecutor Cedric Visart de Bocarme told Belgian television that Amrani had been in jail several times since his youth, and said that police searching his home had not found any further weapons or suspicious items.
Random killings are rare in Belgium. Most recently, in January 2009, a man stabbed two infants and a woman to death and injured 13 at a nursery in the town of Dendermonde.
