A: You need to call a lawyer. APS thinks you had her get the money for your benefit. They might try and remove her from your care and send charges to a prosecutor. I suggest you call a local criminal law attorney and meet with them. This need to be done before you and or mom meet with them. Also, follow up with her Dr and get the record to show she is doing better. You need to protect yourself.
A: It looks as though the offense was out of Georgia? I advise you to speak to an attorney who is licensed to practice in the state of your offense. The answer would depend on what type of battery (assault) If you were convicted in Washington. If the charge included Domestic Violence or was a felony, you would need to restore your right to possess firearms. This only applies if the charge was from Washington and you live here. Since the charge seems to be out of another state, then I suggest you speak to an attorney from there.
A: Your instinct to obtain representation is right. Contact an attorney and try to meet with them. Most lawyers offer telephone or video conferences due to the Sheltering guidelines. Then discuss the benefits and dangers of speaking to the investigator. Finally, do not speak about this to anyone but your attorney.
