Mourners are laying flowers near the scene of the deadly Christmas market attack as investigators puzzle over the motive of the suspect. At the same time there are fears that the rampage could deepen divisions in German society. A church a short walk from the scene of the attack has become a central place of mourning since the suspect drove a car into the busy market on Friday evening, killing five people and injuring 200. A carpet of flowers now covers the broad sidewalk in front of the church. Authorities have identified the suspect as a Saudi doctor who arrived in Germany in 2006 and had received permanent residency. They say he does not fit the usual profile of perpetrators of extremist attacks.
