Your program didn’t explain how this suspect knew that mixing fugu (pufferfish) poison with digitalis could work to delay the effects of the poison to realize his murder scheme. If other experts had to do a lot of additional research to find this combination, how did someone with just a high school education and no apparent relevant knowledge or training know how to combine the 2 poisons? Did the police explain this? It’d seem important to the case to show how he acquired this knowledge.
