Aaron Hernandez may have set up a secret trust fund for his young daughter before he took his own life in his prison cell this year.

The Boston Herald reportedly obtained documents that indicate Hernandez may have established an irrevocable trusts for his five-year-old daughter, Avielle Janelle Hernandez. This type of protected trusts is established then the creator, in this case Hernandez, releases all future claims to the assets in the trust, which are in the complete control of the beneficiary. An irrevocable trust is protected from creditors and additional claims, and the contents of the trust are not on public record.

According to the Boston Herald, Hernandez’s estate attorney filed documents in Bristol Probate and Family Court that made reference to the “AJH Irrevocable Trust.” According to the New York Daily News, a judge had ordered Hernandez’s lawyers to turn over documents connected to his estate.

Hernandez’s estate is the target of multiple legal claims, including a wrongful death suit filed by the family of Odin Lloyd, who Hernandez was convicted of murdering in 2013. There has been much speculation about what, if anything, might be left in Hernandez’s estate, as he was released from the New England Patriots early in his contract when he was charged with murder for the first time.

Hernandez was serving a life sentence of Lloyd’s murder, and was acquitted of the double murder of Daniel de Abreu and Safiro Furtado just days before he reportedly hung himself in his jail cell in April.

Arielle is Hernandez’s daughter with his fiancée Shayanna Jenkins.
