How can I pin murder on Eli, the pedophile?

Question

I'm playing "The Golden Butterfly", the second mission in L.A. Noire's Homicide chapter.

Diedre Moller has been murdered. There are two suspects in the case, her husband, Hugo, and a pedophile, Eli.

I've found all 12 clues in the case, and I'm back at Central where I have the opportunity to interrogate both suspects. I've gotten all four speech successes out of Eli, and he really doesn't seem guilty (of murder). He has a plausible explanation for how he got the brooch, and the coveralls in the trunk are stitched with Hugo's initials. Yet, whenever I accuse Hugo of murder, the captain gets upset with me.

I looked up a walkthrough and discovered that I'm supposed to accuse Eli of the murder.

What evidence proves that Eli, rather than Hugo, is guilty?

Answer 1

The short answer is that there is none. The lack of hard evidence against both suspects is supposed to nag at you. The captain wants you to accuse the pedophile, as he's the better one to put behind bars.

I can't reveal what is going on, though, without massive spoilers:

Neither man murdered Diedre - they're both innocent. In fact, most of the murders you investigate while on the Homicide desk are actually being committed by Garrett Mason, a truth you'll eventually discover in the final case of the desk. The flimsy evidence you have against the two men is actually part of Mason's plot.
