It could be both criminal and civil.
The short answer is yes. Your husband will definitely want to talk to a defense lawyer, and NOT the prosecutor. Most defense attorneys give free consultations. If you find you cannot afford a private attorney, ask for a public defender if and when the state files charges.
Again, do not talk to the prosecutor. Talk to a defense attorney. Do not make statements about the facts of the case in an open forum like this one. It could potentially be used in the future.
