The resident calls the police and Dzhokhar is at last caught, and the resident only noticed anything suspicious because there were bloodstains on the path leading to this boat. Which warrants the question, if the police and army had searched this house and presumably the back garden, why didn't they notice the bloodstains?
They didn't search his house, it was just outside of their search area. IMHO at least, they had to set a limit somewhere and they were close.
