How to document Applicant salary from LLC

[Lois S.]

Our applicant listed an employer and his *supervisor* on his app.  

Researching the company he listed, I find that it's an LLC and he's listed himself as a member and his child as his agent.

So he can create his own paystubs, I'm assuming.  The *supervisor* was unreachable, as I only got a recording when calling the business.

Also see online that the LLC was suspended 5 years ago, but subsequent Statements of Information were filed with Secty of State.

Would checking his personal bank statements be sufficient to verify income?

Any other advice/red flags here?

Thanks
