The tipster alleging potential jury misconduct in the case that landed former NFL star Aaron Hernandez behind bars for life without the possibility of parole is due in court for a hearing on Friday.

The Associated Press reports the former New England Patriots star will be allowed to attend the proceedings, but the judge has ordered the courtroom otherwise closed for the high-stakes session.

Reports are the still unidentified person contacted an attorney for Hernandez and claimed she worked with someone who served on the jury that convicted him as the trigger-man in the June 2013 killing of Odin Lloyd and the panelist was aware that the former NFL star also faced double murder charges stemming from a drive-by shooting in downtown Boston nearly a year earlier.

Hernandez is expected to go on trial sometime next year in the killings of Safiro Furtado and Daniel de Abreu, but all talk of that case was barred from mention during the Lloyd proceedings. In the Boston shooting, Hernandez is accused of gunning down both men at a stoplight outside a nightclub after one of them accidentally spilled a drink on him earlier in the evening and failed to apologize.

Hernandez, who is now being held at the Souza-Barnowski maximum security prison, has denied all the accusations.

Ever since rumors of the jury misconduct allegations have surfaced, prosecutors have openly questioned the credibility of the source and claim since Hernandez has been jailed the woman has penned steamy, sexually explicit letters to him.

Meanwhile, attorneys for Hernandez have also filed several motions seeking to have his conviction in the Lloyd case overturned, among their grievances is their contention that there was not enough evidence for jurors to convict their client him on the legal theory that the shooting of was committed with "extreme atrocity or cruelty'' as required by state law.
