A medical condition that could explain loss of consciousness — raised at trial but never supported with expert testimony. A post-conviction petition containing a neurologist's opinion — filed one day late. A key prosecution witness whose account was contradicted by text messages — never challenged by the defense. At what point does a defense stop being a defense?

Mackenzie Shirilla was convicted of four counts of murder for the Strongsville, Ohio crash that killed Dominic Russo and Davion Flanagan. She was seventeen. The prosecution argued premeditated intent based on surveillance footage, black box data, and a behavioral profile built from threatening text messages. The defense argued POTS — a condition that causes fainting — but presented zero medical evidence to back it up. No expert. No records. No connection between the diagnosis and the crash.

After the conviction, a Cleveland neurologist reviewed her case and found evidence consistent with a seizure episode. That opinion never reached a courtroom because her attorneys filed the petition twenty-four hours past the statutory deadline. The court refused to consider it.

Criminal defense attorney Bob Motta has tried cases at every level. He examines the Shirilla defense failure by failure — the expert who should have testified, the competing evidence that was never introduced, the accident reconstruction that apparently never happened, and whether a client who maintains she has no memory of the crash needed a completely different legal strategy from day one. The question he keeps coming back to: was this a murder conviction — or a conviction by default?
