Yes. They could arrest and charge you with possession with intent to sell even if you were not home and in actual possession of anything when your home was searched and your wife arrested. You could be charged under a theory of constructive possession if what the police found on your premises -- and where it was found -- gave them probable cause
to believe that you'd have to have known of what was going on in the home and been part of the criminal
Probable cause is a very low burden of proof. In order to arrest you and charge you, the authorities would only have to believe that a drug selling operation may have been going on at your house and that you may have had something to do with it. To convict you, they'd have to prove that you were involved beyond a reasonable doubt. So obviously, the fact that you were in jail when your wife was picked up might help your case if you were there for a goodly length of time (like serving a sentence
for a drug prior).
But if you're saying that you were arrested and made bond on a simple possession case only to find that while you were gone the police then raided your house and that as a result they want to add more serious charges, yes, they can bring you back and ask for heavier bond.
There is no deal you should even try to cut with the police if they come back tonight. Police will promise you the moon if you can help, but they are only lying to you. The Supreme Court
has ruled that it's okay for police to use deception to try to get information about crime, and they are trained to be very good at doing just that. But the truth is that they do not have the authority to make any deals. Only the prosecutor does, and prosecutors do not keep the promises that police make to their suspects and arrestees.
As you're at liberty right now and probably have a lawyer from your last case, call him and do what he tells you. He will not recommend your talking to the police.
