Defense attorneys claim in court papers that news media coverage of Marinello's case has biased potential jurors in the case.
The 70-year-old Marinello is charged with second-degree murder in the death of his estranged wife, 45-year-old Liz Marinello of Sumrall.
She died while seeking to annul the marriage on grounds that he had not divorced his previous wife when they married in 2004.
The trial is set to begin the week of May 12th.
Liz Marinello was leaving a regularly scheduled therapy session when she was shot twice in the face on August 31st, 2006. Vince Marinello claimed he was driving to Jackson, Mississippi, to watch a Saints game with friends at the time, but Jefferson Parish Sheriff's Office detectives say he shot her before beginning the four-hour drive.
