What is the function of じゃ at the end of this sentence


I know the meaning of the whole sentence but what is the function and meaning
of じゃ at the end of the sentence:

> お巡りさんには関係ありません じゃ

I checked on the internet and maybe じゃ means "I guess".




Without further context, it should be a contracted じゃあ
([じゃ](https://dictionary.goo.ne.jp/word/%E3%81%98%E3%82%83/#jn-101354) #2),
meaning _bye_. It is a way to end the conversation.
