Authorities have determined that Lauterbach's child had not been born at the time of her death, Hudson said, so prosecutors can only charge Laurean with one count of murder.

The grand jury also charged Laurean with robbery with a dangerous weapon and a charge involving an unauthorized financial transaction involving card theft. The indictment states Laurean forced Lauterbach to remove money from her bank account Dec. 14, the day authorities believe he killed her.

Laurean is also accused of trying to use Lauterbach's ATM card on Christmas Eve, and was charged with attempted card fraud and obtaining property by false pretenses.

Authorities believe Laurean entered Mexico on a bus Jan. 14, two days after he left Jacksonville. Earlier this week, a man identified as his cousin said Laurean walked into his liquor store in Guadalajara last week, but left without saying where he was headed.

"Because of the all the attention, I hope (Mexican authorities) will move on this case very quickly," Hudson said.

Christina Laurean is still cooperating with investigators, and she does not face charges, Hudson said. She learned of Lauterbach's death roughly a day before Laurean fled, but only then told police and turned over the note he left behind, according to court documents.

Authorities have previously said Lauterbach was killed Dec. 15, citing the timeline provided by Laurean's wife. Hudson declined to address the discrepancy in detail, saying only that the "best evidence available" now indicates Lauterbach was killed Dec. 14.

Although Laurean refused to speak with detectives looking into Lauterbach's disappearance before he fled, authorities have said they didn't consider him a flight risk because they had information the pair had a "friendly relationship" even after she reported the rape allegation to military authorities.

Lauterbach, of the Dayton, Ohio area, had accused Laurean of rape in May, a charged he denied. Naval investigators have said they have no evidence to corroborate Lauterbach's claims, but Lauterbach's and Laurean's regimental commander was intent on taking the case to a hearing that could have led to a trial.

Laurean had told members of his unit that he would flee to Mexico if it appeared he would be found guilty. Laurean, of Las Vegas, was born in Guadalajara. Family members there have said he moved to the U.S. more than 10 years ago.
