Hologram woman

A so-called "hologram woman" was the supposed owner of an Arcadian diamond. When Captain John Hart "almost got [his] hands on her", she created a Rift storm to send canisters supposedly holding directions to the diamond out of the other side of the Cardiff Rift. In actuality, the diamond didn't exist and the canisters held parts to a bomb that latched onto the DNA of whoever killed her. The bomb also projected a hologram of the woman that would tell John this. John shot her, which attuned the bomb to his DNA. (TV: Kiss Kiss Bang Bang)
