Elwen Evans QC, prosecuting, has asked Mark Bridger about April Jones' parents, Paul and Coral.
Mr Bridger said: "I can't even start to understand what they were going through. It was through speaking to [my boss] and the postman that I knew there was a huge search going on."
Miss Evans: "You had killed an unknown little girl."
Mr Bridger: "Yes."
Miss Evans: "You didn't even bother to find out who that little girl was."
Mr Bridger: "What was I supposed to do? Knock on people's doors?"
He said he 'didn't recognise' April that night because it was 'dark'.
He told the court: "My instinct was to go to the police station."
Miss Evans: "Did you go?"
Mr Bridger: "No."
