Police reportedly believe Shayanna Jenkins, who is also the mother of Hernandez's baby, may know what happened to the missing murder weapon in the investigation into the Boston semi-pro football player's June 17 death.

The warrants claim Jenkins may have dumped the weapons in the woods in Massachusetts or may have taken them to a Connecticut storage unit in Bristol that Hernandez paid for. Police have searched the unit, which was reportedly leased in Jenkins' name and paid for with Hernandez's credit card.

According to the documents obtained by the paper, evidence against Jenkins includes surveillance video from Hernandez's home, text messages from Hernandez and an interview with Jenkins' sister.

The day after the 27-year-old Lloyd was found dead in a field near Hernandez's home in North Attleborough, Mass., surveillance video reportedly captured Jenkins leaving the home she shared with the former NFL star carrying a trash bag. Authorities said it looked like it contained a hard container, like a lock box or a safe, the paper reports.

Jenkins allegedly placed the bag in the trunk of a red Nissan. When she returned to the home about a half hour later, the bag was nowhere to be found, according to the paper.

Investigators also revealed through the newly released documents that Hernandez sent text messages to his fiancée referencing a box in the basement.

Police spent several days searching a pond near Hernandez's uncle's home in Bristol, Conn., but they did not recover the .45 caliber Glock used to kill Lloyd.

Jenkins has not been charged with any crime in the death of Lloyd, who was the boyfriend of her sister.

Hernandez, 23, was arrested June 26 and charged with first-degree murder in the death of Lloyd. He was released from the New England Patriots following his arrest. Prosecutors say he orchestrated the execution-style shooting because Lloyd talked to the wrong people at a nightclub. He is being held without bail and has pleaded not guilty.

Two Hernandez associates, Ernest Wallace and Carlos Ortiz, also face charges in Lloyd's death. Wallace pleaded not guilty to a charge of being an accessory to murder after the fact. Ortiz has pleaded not guilty to a gun charge.

A probable cause hearing in the case is scheduled for Aug. 22, unless a grand jury indicts him before then.
