All I have is the publicly available evidence, but that pretty strongly indicates guilt.

he was found a state over, at a mcdonalds. With a fake ID that was the same name that was used to check into manhatten, and for transport. with a bag containing a loaded 3d printed handgun that matched the footage.

He also had writings which are not public but have been stated to indicate his mindset prior to the murder, and a notebook that contained detailed travel plans and how to avoid capture.

Like pacifist said though, the police are tripping this case up, the biggest defense for Luigi at the moment is the ineptitude of the police during the arrest sequence and investigation. They have already succeeded in throwing out medical records due to improper acquisition, have been found wiretapping attorney lines (which IMO should be an immediate opposing party wins regardless), and are in the process of trying to throw the bag out that was found at mcdonalds due to improper search and seizure claims (although I don’t personally think this will happen, it’s pretty clear the search and seizure laws in that state clarify that a search will happen on any arrest regardless of case)

the only way I can see him getting a “innocent” verdict is Jury nullification, so I am not leaning on that, because even if found innocent on the second degree murder charges, based off publicly available evidence the prosecution still has a fairly strong case of stalking charges. Plus he still is facing the same charges at the state level as well, as the judges ruled it isn’t considered double jeopardy for someone to be trialed both federally and state side (which IMO is wrong but I digress)
