2018 Jungfernstieg double murder

On 12 April 2018, 34-year-old Sandra P. and her one-year-old daughter Mariam were murdered at the Jungfernstieg S-Bahn station in the Neustadt quarter of Hamburg, Germany. The perpetrator, 33-year-old Mourtala Madou (also Mado Bido Mourtala), the Nigerien ex-boyfriend of Sandra P. and father of Mariam, was arrested at the scene and convicted of two counts of murder in 2019.

The case was of significant public interest as the murder and preceding argument occurred in view of several bystanders. The Alternative for Germany (AfD) heavily focused on Madou's asylum seeker status, arguing that he should have been deported; Madou had no prior criminal record and a valid residency permit, but was considered a potential risk to his child by Jugendamt due to known anger issues.
