Locals are focusing in on motive which seems at this point very difficult to narrow down. Here is a summary of possibilities written by me on a local FB discussion page: " Was it revenge on her family for something? Was it a rape, then murder to cover that crime? Was it someone who exploded in rage when she came upon a drug deal or refused to give money to someone approaching her for that? Was it a love triangle crime of passion (I doubt this one, but am brainstorming all possibilities)? Was it someone who kept watching her walk by his house, and decided to sexually assault her. When she fought back, he hit her? Had she found someone embezzling money at SPIKE and threatened to expose him/her? This last one is doubtful as a friend who worked there said there are so many checks and balances in that organization, fraud would be very difficult. Thelma worked in that dept. though. Was it an indigenous person angry with all of the disappearances of indigenous women who wanted to see a white woman disappear for a change? There is some gossip on reddit that one such guy was overheard in a pub saying to another, "Remember when we killed that white woman?" but I think they just wanted to upset the white men in the pub or this is made up by the reddit poster. Was this a man from the Speedway who took a shine to Thelma, but she rebuffed him, and he got angry? Was it someone with prior DUI s who hit her by mistake with his vehicle, and he panicked to cover up the accident? Any other ideas?
