The thieves left contact info., which, so far, has proven to be untraceable.
A week ago, it was reported that burglars broke into Big Sean's home in the Valley while the rapper was on a trip to Dubai. They apparently cracked a safe and stole around $150k in jewelry as well as some unreleased music. TMZ now reports that the robbers left a note for Sean to discover that provided an e-mail address to contact should he want to get his things back.
Thus far, police have not been able to trace the address that was left on the note. The investigation has now been turned over to a "special unit" within the LAPD.
The thieves likely expected authorities to discover the note, so it seems it was left as a sort of taunt. On the other hand, maybe they want to get in touch with the Detroit rapper and put a price tag on those unreleased tunes.
