The law firm reported the theft to the police who referred it to the District Attorney/State of Texas.
She needs an attorney as theft of greater than $200,000 is a 1st Degree Felony punishable by prison sentence of 5-99 years or life and up to a $10,000 fine. If she has a defense she needs an attorney that can start working for her to prepare it. If she didn't do it, it should be easy to prove she didn't but she cannot waste time. If she cannot make the bond, an attorney can try to get it lowered but might not be successful.
You can help by determining what her assets are to be able to pay a lawyer and perhaps even calling one/several for her. Be cautious though about speaking with her at the jail as the conversations of inmates are recorded and can be reviewed and used against the inmate.
Good luck to her
