Investigators in the murder case against Aaron Hernandez recently searched a storage unit rented in the name of his fiancee, The Hartford Courant reported.
Authorities conducted the search of the unit rented to Shayanna Jenkins because they believe she made "overt attempts to hide evidence ... and to hinder and mislead" the investigation, the paper said, according to court documents released Friday.
Investigators did not seize anything during their July 26 search of the unit in Bristol, Conn., which is Hernandez's hometown.
Jenkins has not been charged in connection with the June 17 shooting death of Odin Lloyd, her sister's boyfriend.
According to the newly released documents, investigators cite surveillance video, text messages and an interview with the sister, Shaneah, to suggest Shayanna Jenkins may have had knowledge of what happened to the gun used in the shooting.
Hernandez, charged with first-degree murder, has a probable-cause hearing scheduled for Aug. 22, unless the grand jury indicts him before that date.
The documents say Hernandez called Jenkins the day after Lloyd's body was found because he wanted to dispose of weapons in the house.
Footage from June 18, according to records, shows Jenkins leaving the house in the afternoon, carrying a trash bag, which authorities say contains a heavy "rigid object," resembling a lock box or safe. After putting the bag in the trunk of the car, Jenkins later returned and opened the trunk of the car, which no longer held the trash bag and "rigid object," the records show.
Carlos Ortiz, one of the suspects charged in connection with the case, told police after the shooting that Hernandez stashed two guns in the basement of his home in North Attleborough, Mass.
Acting on a tip, authorities also recently conducted a five-day search of a Bristol pond where it was believed the murder weapon was possibly discarded.
