Two men found dead in mystery shooting as cops find key clue at crime scene in Germany

MYSTERY surrounds the death of two men who were shot dead in Germany as investigators discovered a key clue at the crime scene.

Police said the two men died in an overnight shooting in the Langenhorn district in Hamburg-the second deadly shooting in the city this month.

Police said they had concluded an operation and were now investigating.

Police were called shortly before midnight as 28 vehicles rushed to the scene on Reeborn Street, reported.

Officers discovered the two men on the pavement between two apartment buildings.

Both are said to have succumbed to their gunshot wounds, according to the outlet.

A revolver was found next to one of the victims indicating he may have shot his victim before turning the gun on himself.

A spokesperson declined to comment on the perpetrator.

It comes as earlier this month, a former Jehovah's Witness stormed into the Kingdom Hall in Hamburg and went into a rampage leaving six people dead- including an unborn baby.

The gunman, named as Philipp F, 35, who had left the group "not on good terms," opened fire through a window and then stormed inside the building.

He fled to an upper floor before shooting himself dead, police said.
