Here's the statutory law that would concern you:
281. (a) Every person having a husband or wife living, who marries
any other person, except in the cases specified in Section 282, is
guilty of bigamy.
(b) Upon a trial for bigamy, it is not necessary to prove either
of the marriages by the register, certificate, or other record
evidence thereof, but the marriages may be proved by evidence which
is admissible to prove a marriage in other cases; and when the second
marriage took place out of this state, proof of that fact,
accompanied with proof of cohabitation thereafter in this state, is
sufficient to sustain the charge.
283. Bigamy is punishable by a fine not exceeding ten thousand
dollars ($10,000) or by imprisonment in a county jail not exceeding
one year or in the state prison.So yes, it is a crime, and yes, he can be prosecuted. Check with the District Attorney in your county.
