The case of Corey Binderim is food for thought. He was a handyman with a lot issues - drugs, debt. Kept up a facade as a family man with kids. Generally a likable guy - not a white van creeper. He agreed to help an elderly lady remodel her bathroom. She prepaid him $12K. He then proceeded to spend the money on drugs, alcohol. He started flaking on the lady. She got frustrated that her bathroom wasn’t getting done and started complaining and asking for her money back. She told him she would report him to the police and had an attorney. He went into a spiral because he could not pay the money back and he was about to be exposed as a fraud and drug addict. He was hiding the problem from his wife and 2 daughters, but they were on the verge of finding out. Desperate to cover up this mess he created he went to the lady’s house and strangled her. Took her remains to the dump. He was eventually caught.
Point being - a motive could be payment of a debt - even a small debt. $12k to a handy man or other average Joe with no money could be a pain point for a desperate person to try and make the issue go away. So perhaps the motive revolves around someone she paid for a service that wasn’t done. Going into the house at night and disappearing her aligns more with needing to silence her over something versus breaking in looking for a coin collection.
