When I lived in Miami in the late 80s/early 90s there was a story about how the main courthouse in Dade County had to clean up various parts of chickens, goats, etc. most mornings from around the property. Allegedly, these were sacrifices from practitioners of various Afro-Caribbean religions (just like the article says) seeking to influence ongoing court cases.

It sounds a bit crazy, but at that time there were fairly frequent stories in the news about Santeria, etc. followers being arrested for sacrificing goats in their backyard and so on.

I stepped into an elevator in an office building once and there was a (live) rooster in it...
