The police did not know at the time that Mr. Lozier and Ms. Sullivan had kidnapped the woman earlier in the day, prosecutors said. Once they were back in the S.U.V., Mr. Lozier threatened to hit the woman, and he told her that she would never see her children again, according to prosecutors.
Eventually, prosecutors said, Mr. Lozier dropped the woman off at a detention facility in Mississippi instead of taking her to Louisiana because he was worried about legal trouble, prosecutors said.
Sayler A. Fleming, a U.S. attorney, said in a statement that the sentencing on Wednesday should “reinforce that those who work in the fugitive recovery industry must comply with state and local laws and regulations and treat those they take into custody with decency.”
“They work in a dangerous industry, but that is not a license to go rogue,” she said.
Tyler K. Morgan, a lawyer for Mr. Lozier, said in an email that he was “disappointed in today’s outcome.”
“This was a licensing issue that should have been resolved in state court,” he said. “Now the fight continues on appeal.”
