The sudden assassination of the envoy caused European public opinion, which was already unfavorable towards the Ottomans, to become completely one-sided, and even the politicians, experts, and scholars who had previously tended towards supporting the Ottomans had now fallen silent.
As a result, the Vienna Government, on May 7, 1882, just three days after the incident, terminated the second round of negotiations.
Immediately following this, on May 9, the Vienna Government issued an ultimatum to the Ottoman Government, demanding they hand over the perpetrators behind the "massacre" within a week.
This wasn't a matter of agreement or dissent; it was simply impossible to achieve.
The massacre involved such a vague group of people, and the identities of the victims, their numbers, and the location of the crime were all undefined. It was impossible to know where to start an investigation.
