There have been a few stories in the English-language press about Lauren Mann, the American girl who was found dead in her Vienna flat, such as this one in the Local and this one in the Daily Mail. None that I have seen mentioned her the do-gooder background to the incident.
"Lauren had a big heart for poor people", says people who knew the dead girl, "she often went to railway stations and asylum centres, where she distributed food and blankets." She even started friendships with many of them. Such as Abdou I [the Gambian "refugee" who has been arrested in Switzerland, suspected of her murder]. "Yes, she knew that he was threatened with deportation. No, she didn't know about his criminal past." [He was wanted for thefts, robberies and child abuse in Germany]
The student wanted to help the Gambian. She offered him accommodation, fed him, bought cigarettes and clothes for him. And in the days before her death made desperate posts on Facebook asking her friends to put the 24-year-old up temporarily. As he was expecting a visit and so needed substitute accommodation for him during this time.Source
