Factual error: Like in the previous movie, the female lead introduces herself formally as Detective Maggie Price, from San Francisco Police Department. Where the correct rank is "Inspector."
Factual error: The search that cracks the case is nonsense from a simple logical standpoint. There are three people, whose deaths have never been related together, but that all died because of tetryzoline poisoning. Entering all three of those names in google would not produce relevant results or even narrow the spectrum, because it's three unrelated deaths. (01:08:40)
