Paula - If she hasn't already, tell her to go to the nearest police station, check in with the desk sergeant, explain the situation and sit tight until she can be seen. I have no doubt that they will contact where ever she came from and report this situation as this is illegal to ask someone just released from jail to walk the streets, alone for the entire night.
By doing this, she is, at least safe and at best, not breaking any laws.
I just talked to my cousin who is in law enforcement and the system, everywhere is not perfect and to go one step further...not really very good as all departments are so under staffed so extra steps must be taken.
Let me know.
