Sigrid insisted she had simply been in shock, frozen, a horrified bystander.

It was a serviceable story, and it might even have worked — except that Detective Osei had recovered the visible pantry camera itself, the one Lars thought he’d disposed of, from a trash bag behind Sigrid’s rental property.

Its internal clock and the fragment of memory still on it matched the concealed backup exactly, second for second.

You cannot claim a recording was faked when a second device, thrown away by the defendants themselves, corroborates it to the second.

That second camera was the hinge of the whole case, and there is a lesson in it about how people like Lars and Sigrid destroy themselves.

Their defense — the footage was manipulated — was not a bad one on its face.
