[ WP ] A serial killer leaves a certain song playing at every crime scene , but no one knows what it means

* Four bodies this month 
 * radios near them. 
 
 what are the connections? 
 it just does n't seem to add up. 
 
 Detective Elmwood sighed and looked back at his computer screen to see more details on the body, maybe something he missed. 
 
 Nope, he had covered every crack, nook and cranny in that house. but nothing added up. No murder weapon, locked doors, no chimney. all of the things for a real Sherlock Holmes case. 
 He wrote that in his notebook just to be sure. you know? he just could n't concentrate with that stupid Justin Beiber song stuck in his head. 
 
 who likes that guy anyway?
