"What is そいつら and what kind of conjugation is 知らんからな?


I was wondering what そいつら means, and is 知らんからな slang? Here is the sentence:

> 俺はそいつらのことよく知らんからな。

I know they slur their vowels to make things easier to say. Or maybe this is a
new word that I can't find in the dictionary.




そいつら means "they"(or more precisely "the fellows"). When "ら" is added to a
pronoun, it becomes a plural one. For example, 彼 means he, and 彼ら means they.

知らん means 知らない, which is kinda oral expression. The whole sentence means
"because I don't know much about them".
