I'm not questioning your four sins but want to follow up reading along these lines.

Well the original source is, as usual, the Scriptures.

In the case of willful murder, Genesis 4:10 -

And He said to him: What hast thou done? the voice of thy brother's blood crieth to me from the earth.

In the case of sodomy, Genesis 18:20,21 -

And the Lord said: The cry of Sodom and Gomorrha is multiplied, and their sin is become exceedingly grievous. I will go down and see whether they have done according to the cry that is come to me: or whether it be not so, that I may know.

As for oppression of the poor or downtrodden, Exodus 2:23,24 -

Now after a long time the king of Egypt died: and the children of Israel groaning, cried out because of the works: and their cry went up unto God from the works. And he heard their groaning, and remembered the covenant which he made with Abraham, Isaac, and Jacob.

Finally as to fraud, James 5:4 -

Behold the hire of the labourers, who have reaped down your fields, which by fraud has been kept back by you, crieth: and the cry of them hath entered into the ears of the Lord of Sabaoth.

These are the four passages in Scripture in which God responds to sins that cry from the earth.

Summa II-IIae 108, 1 deals with some of this.
