Syko Sam: What Record Label was he on before he was arrested?

I'm doing a lot of research on Syko Sam AKA Richard McCroskey. I've
found a lot of references to SKR, a record label I recently fell in
absolute love with (totally unrelated) Anyhow I've also found
references that he was an independent horrorcore rapper without a
label. So if anyone Knows, maybe has a direct link or something...It
would greatly be appreciated.
