Anette Walden lived on the same street as Ansbach suicide bomber Mohammad Daleel and grew to know him well after her voluntary work supporting refugees in the area.
The school teacher said after Daleel had an operation on an injured arm she visited him in his hostel to help feed him.
The naive German woman nourished a poisonous snake.
Syrian refugee, Daleel carried out a suicide attack at a music festival on Sunday (July 24) injuring 15 people and it has since been reported by Bavarian Interior Minister Joachim Herrmann that he had left behind a video pledging allegiance to ISIS leader Abu Bakr al-Baghdadi.
Some people learn the hard way.
Ms Walden added: “Personally, I just told my friend; everybody needs to go back home."
