First off, did the neighbor capture it or acquire/buy it somewhere?
As the others mentioned, the harmless little tike needs no restraining. And it's definitely a "Miami" phase cornsnake, either locality-specific or captive-bred. It's a beauty either way!..
I've seen juveniles that look exactly like that one that were found down in southern Miami/Dade County as well as the next county north in Broward County, Florida. Those are some of the prettiest corns there are in my opinion...
