Immigration status and deporting criminals

A friend of mine was a victim of a crime and she has since left Cayman. I understand the offender is a foreign national but it is unclear if he is a permanent resident or perhaps has Caymanian status. Does his immigration status affect whether he can continue to live in Cayman once he gets out of prison? I want to know if he will be deported after he serves his sentence or be able to remain on island. Does immigration follow up on cases like these? How does the process work?
