If there are more people that might want that mark dead, then you can rest assured that nobody will suspect you. However, it is always a good practice to leave the city the day that our gangster will estimate for the job to be completed. You could travel to a different city and visit some shopping malls that have surveillance cameras to create an alibi in case the police will start asking a question.
