Can my daughter obtain a divorce while she is still pregnant?

My daughter is in her last year of law school in Mississippi! She married a young man from Oregon because she is pregnant! He misrepresented himself by heavy drinking, religious preference, drug use, etc. which became apparent in the days after the wedding! This week he threw my 6 month pregnant daughter against a wall! She went to E. R. with severe bruising and small contractions! He left the next day with his few things in a U Haul en route to Oregon. He called and told her he would return in a week to "put his foot down and take her back to Oregon". She filed a police report and they could not find record of him with the birth date that he had provided! Hmmmm? My question is, can she be considered a resident of Louisiana? Her house is in my name, but she has been there for almost three years while in school? If so, can she obtain a divorce in Louisiana while she is still pregnant? Thank you in advance for your time!
