Many criminal defense attorneys will work out a payment plan for the criminal charge but most will want a substantial amount upfront. If you can't afford a criminal charge I would suggest doing is requesting a public defender.
I generally do not do many criminal cases in dillon. I would consider calling Henry "hank" Anderson in Florence.
However, I would be happy to talk to your sister about a possible civil case she might have against the cop.
Unfortunately, not that unusual. You can use AVVO search to find a local attorney, or if you cannot afford one, each defendant should ask the court to appoint an attorney. You may also want to contact a civil rights attorney about the brutality, but take care of the charges, first. And, stay away from dope and people who have it. It can cause you tremendous problems.
We do not have a client/attorney relationship until you make an appointment, we discuss your case face to face, I accept a retainer, and we explictly agree to enter into representation.
