If Leona, Determined dies before her attack trigger resolves, does the trigger still resolve and stun a unit?

Ruling: If Leona dies before her attack trigger resolves, the trigger resolves but does nothing because her location is 'null' and the term 'here' cannot find a legal target.

Sequence:

• Leona's attack trigger goes on the stack
• Leona dies before the trigger resolves
• The trigger resolves but her location returns as 'null'
• The term 'here' cannot find a legal target
• No stun occurs
