Earlier this month, the former New England Patriots tight end's legal team set forth with filing certain motions that document their client had an unfair murder trial.

His lawyers requested the majority of their filings remain sealed from public consumption.

Convicted Murderer/Former NFL Player's Lawyers Filed A Motion Claiming A Juror Was Unfairly Influenced

FOX 25 in Boston reported this news last Monday about Hernandez's lawyers filing four motions in his appeal to overturn his conviction with the Bristol County Superior Courthouse in Fall River.

One of those motions is titled, "Defense Motion for post verdict inquiry respecting a juror's exposure to extraneous matters," meaning the ex-NFL player's legal team believes that during their client's murder trial for the Odin Lloyd case one of the jurors was exposed to information outside of the courtroom that could have critically impacted the trial's outcome.

As previously mentioned, the convicted murderer's lawyers have requested that the documents they filed be sealed and kept from the public so it is unclear what the exact nature of these allegations is.

MassLive reported Thursday that the Bristol County District Attorney's office is asking the Superior Court not to seal the documents that Hernandez's legal team filed.

"The law places a heavy burden on any party seeking to impound court documents or to exclude the public from court proceedings," wrote Assistant District Attorney Roger L. Michel, Jr., in a court filing on Thursday, adding, "Impoundment is always the exception to the rule."

Michel, Jr. pointed out that Hernandez's arrest and trial garnered nationwide interest so the public has every right to stay informed.

"There is simply no appropriate basis for impoundment here," his filing said.
