A police search of Kansi's apartment turned up the hidden AK-47 under the couch. Ballistics tests confirmed it was the weapon used in the shootings, and Kansi became the chief suspect of the investigation.[1] He was listed as one of the FBI Ten Most Wanted Fugitives.[11] The search focused on Pakistan, and agents spent the next four years following hundreds of leads, taking them as far afield as Thailand, but to no avail.[3] Kansi would later reveal that he had spent this time being sheltered by fellow Pashtun tribesmen, in the border regions of Afghanistan, making only brief visits to Pakistan.[3][4]
