Hi All, first post here, but have been lurking for some time. Been following this case from the beginning. I've had some thoughts about what may have happened.
While it's possible this was about more than money, I feel like it is most likely about money. I get the impression that maybe IK planned to rob the coffee hut, but then found that there was not much money to take. From there, I'm thinking things just spiraled out of control and that he really didn't have a plan for all of this to happen the way it did.
My thought is that he tried to rob the hut and there wasn't very much money in the register and then perhaps tried to steal money from Samantha, but being a young girl, she also did not have a lot of money on her. At this point, he could have just left, but maybe he was angry and determined to get cash. Holding Samantha at gun point, demands she give him money. Being scared, she states she has none on her. Maybe mentions that she does have a debit card, but its not on her. Perhaps she thought if he took her out of the coffee hut and into the streets, someone would see them or perhaps she could escape, or even that this would buy her time. He takes her into his truck and then maybe put her into his shed.
She gets him the card and he finds that there is no money in the account and then maybe kills her in a fit of rage. Does anyone know if the card was inserted into a ATM machine to check the account balance that night she was taken?
At this point, IK had no plan. He just hoped to keep getting as much money as he could while traveling further and further away, but never had this plan in mind. He made a lot of dumb moves, I find it hard to believe that he had this all thought out. JMO.
