The Bexar County Jail releases inmates 24 hours a day. An individual can be processed as an in & out from the Magistrate’s Office (which basically means it is done in a relatively short period of time). If a bond is not ready or is not going to be posted the individual will be transported to the main jail for regular processing.
If a judge grants an inmate a Court Ordered Release for that day the inmate will be processed out before midnight. The jail personnel have to wait for the information to come across from the courthouse. It is not sent until an hour or two after the end of the business day. Once at the jail it must be processed before the inmate is released. The inmate handbook states the time frame for release as being between 4:00 pm and 12:00 am. However, from what I have been able to find out the time frame seems to be closer to 8:00 pm to 12:00 am for this type of release.
