Q. Can my fiancé be charged if unaware of friend's possession of drugs?

March 9, 2025

A: Yes. The state can charge anyone with possession if they were around or near the drugs. Constructive possession means having access or control of a substance. If someone is arrested does not mean that they are guilty. A person arrested does not mean that they will be convicted. It is important that if arrest a person should remain silent and seek a lawyer.

Q. Arrested for felony theft after delivering stolen package, seeking compensation for ordeal.

March 7, 2025

A: It seems like you may still have a criminal case. If so you should hire the best defense lawyer in the area where the court is located. I would suggest looking for any attorney who has at least 10 years of experience, is a member of a national (NACDL) and NH specific criminal defense lawyer organization (NHACDL). Then ask local lawyers, police bailiffs who is the best lawyer in the area?

Second, after winning the criminal case or getting it dismissed then you may seek a civil suit. I would use the same process to pick a highly regarded PI lawyer.

Q. Can first-degree assault charge be annulled in NH with completed probation and criminal history?

(b) First degree assault under RSA 631:1;
