Just as the game starts, you will come across a vengeful Aiden Pearce trying to get some answers from a hired murderer, Maurice Vega.
The story tells us that Maurice Vega apparently took some cash from an unknown source to finish off Aiden Pearce and his niece, Lena Pearce. After finishing the job, Maurice disposed off 8 Burner Phones throughout the Chicago.
Watch Dogs Burner Phones Locations
Watch Dogs Burner Phones are practically useless, but can be hacked to divulge all conversations Maurice had with the unknown caller. These 8 Burner Phones are a part of ‘Investigation’ that Aiden must carry out to uncover the murderers of her niece.
Like I said, Burner Phones can be located throughout Chicago, but you can make it relatively easy by unlocking all ctOS Towers which will mark all 8 Burner Phones location on your Mini Map.
Finding all Burner Phones unlocks the Vespid LE vehicle and Sanity Check Achievement/Trophy.
