Thomas' cause of death is not known, Judice said. An autopsy on the body will be conducted by Lafayette Parish Coroner Ken Odinet, but it is not known when it will take place.
No charges have been filed against the man who shot Thomas, and it is unlikely that the man will be charged, Judice said.
"In the state of Louisiana, you have a right to protect yourself and others from imminent bodily harm," he said. "We believe at this point, based on evidence and statements collected, that this guy was acting in defense of Ms. Arceneaux and thus, was within the state law."
The Arceneaux family said they wished the ordeal had ended differently, but they believed they did what they had to do to save their loved one.
"I hate that it happened like this because I don't feel like anyone should lose their life," Arceneaux said. "My prayers go out to the Thomas family and I'm sorry for their loss, but we had to save our niece."
