If he's still incarcerated and bail is $0 than he can't be bailed out. If there are no charges pending but he is still incarcerated then he likely took a plea and is serving a sentence.
No Bond Hold This could happen if the defendant is considered a flight risk, poses a danger to others, or if there are reasons to believe they may tamper with evidence or intimidate witnesses. In such cases, the judge may issue a “no bond hold,” which means the person will remain in custody until their trial.
No - if you signed the bond it doesn't matter whether you have a job or not - or whether the bondsman asked you if you did. You are liable as surety on the bond - having a job or not has nothing to do with your liability. Sorry.
Processing time: Once bail is posted, the jail needs to process the paperwork and verify the funds before releasing the defendant. This can take anywhere from 30 minutes to several hours, depending on the jail's workload and staffing levels.
