I want to know the answer to the following question:
On what day were King Dom Carlos I and and his heir, Prince Royal Dom Luis Filipe, Duke of Braganza, murdered?
All the background I'm provided with is that "On 1 February 1908, the king Dom Carlos I of Portugal and his heir apparent, Prince Royal Dom Luís Filipe, Duke of Braganza, were murdered in Lisbon.". Is that enough to answer the question?
Answer: yes
