Mourners laid flowers near the scene of the deadly Christmas market attack on Monday, as investigators puzzled over the motive of the suspect and his previous encounters with authorities were scrutinised.
The Johanniskirche, a church a short walk from the scene of the attack, has become a place of mourning since the suspect drove a car into the busy market on Friday evening killing five people. A carpet of flowers now covers the broad pavement in front of the church.
