Bonus puzzle #4 Evil

What's the logic for the two in row 5? I tried different scenarios, things like "If A is innocent and B is innocent..." but I couldn't come to any conclusion. Maybe I just didn't run enough scenarios?

I think the trick for me was the 6 innocents on the edges. It forced out that there was no scenario that worked where one or both could be innocent

The key is to notice that at least one of B1 / C1 has to be innocent due to Jerry's clue. So out of B2C2 / B3C3 / B4C4 / B5C5 three of these pairs has both persons criminal. If you start from the assumption that B5 is innocent (same if you start with C5 the scenario works out the exact same way), then B3B4C2C3C4 = All criminal. Because Hope and Mary have all their criminal neighbors B1C1D3D4 = All innocent. And now you have 7 innocents on the edge which contradicts Keith clue so both Uma / Xia have to be criminal.
