Small note: the radio transcript has "Kruger Industries" at the top. (If I had to guess, I'd suspect that was its name until you didn't want it on the same card as Kreutz?)
Anyway, that aside, this is very well done. It was a lot of fun to piece things together (sometimes literally!), and I loved the chains of inferences necessary to answer the questions. (I did somehow get the first two cameras swapped, so my inferences weren't perfect. There's also a weird little inconsistency there about whether they were carrying a picnic basket or lunch boxes?)
Excited to see how it ends up if you keep working on it!
