First thought is to return him, unless your son is an adult and willing to take the chance of being bitten. A dog who shows this much aggression is probably not safe, and probably never will be though he can probably improve with the right training and lots of time.
If you decide to keep and try rehabilitating him, DO NOT USE any negative type methods, use physical corrections or try to intimidate the dog in any way; this will only make matters worse. Find a qualified, positive-only behaviorist and have them come in to do an assessment and develop a plan.
In the meantime, you and your son should ignore the dog completely, let your wife and 'other females' do the feeding, walking, interacting. They can feed the dog delicious treats if you and your son are around, but you and your son should not interact with the dog. The dog should also not be allowed free roaming of the house without supervision, especially if you have young kids. You can confine him to a room using a baby gate, or use a crate if he's crate trained and you have a large enough crate.
Good luck, and do please keep us informed of your decison.
