You killed the target.

Rufio is the target, kill someone other innocent person then wait for him to come then kill Rufio.

yea i killed a beggar but no1 came wen i slept do i have 2 do a night mother ritual?

Find a beggar - kill him - check your stats to see if you have: Innocents Murdered - 1 then you can rest and the Speaker will come with orders to execute Rufio.
