To be fair, the mother (or aunt? seems like he has lived with multiple relatives and the media often refers to "the family" broadly) has said that the jogger would tell them that "He was going out for a jog". So there is the possibility that he had cultivated a reputation of a love for jogs in his family, who then mistakenly and genuinely believed him and then repeated that to the media (if being extremely generous to the family). If I were a burglar, declaring myself a jogger would be a great cover for scoping out neighborhoods to burglarize. Agree that his regular (jogging-atypical) clothes and his irregular jogging hours which range from the afternoon to after dark help destroy the narrative though.
