( CNN ) -- Former NFL player Aaron Hernandez put guns into a black box after returning home the night his friend Odin Lloyd was killed , according to new documents obtained by CNN . Hernandez has pleaded not guilty to murder in Lloyd 's death . Another friend , Carlos Ortiz , 27 , told investigators that he observed the former New England Patriots tight end putting firearms into a box in the basement of his North Attleborough , Massachusetts , home , including a small handgun that Hernandez had asked Ortiz to retrieve from the floor of the car they were driving . Ortiz then bought it into Hernandez 's home , according to the document . Ortiz stated that he also had seen Hernandez enter the home and walk into the basement carrying a large handgun earlier in the day . This is consistent with a statement made by a prosecutor in court in late June . `` The defendant goes walking through the house with the gun in his hand . That is captured in the video . ... And they all go down to the basement , '' said Bill McCauley , first assistant district attorney for Bristol County , Massachusetts . `` Once in the basement , the surveillance gets shut off . '' Authorities have said Hernandez , Ortiz , and Ernest Wallace , 41 , picked Lloyd up from his Boston apartment early on June 17 . Surveillance cameras showed the car at an industrial park near Hernandez 's North Attleborough , Massachusetts , home . The documents also reveal the involvement of Tanya Singleton , 38 , a cousin of Hernandez . After leaving Massachusetts , Wallace dropped Ortiz off at Singleton 's Bristol , Connecticut , residence . Ortiz told authorities that he spoke with Singleton about Lloyd 's killing . Singleton lives near a lake in Bristol where a state police dive team was searching for an item linked to Hernandez 's case . According to the documents , Singleton also allegedly assisted Wallace in fleeing authorities . She has not been arrested or charged . Authorities collected Singleton 's credit cards and cell phone . According to the search warrant , Singleton allegedly purchased a bus ticket for Wallace to travel from Macon , Georgia , to Miami . Authorities arrested Wallace in Miramar , Florida , on June 28 . It is unclear how Wallace traveled from Bristol to Macon . Wallace also regularly used a cell phone paid for by Singleton , according to the documents . CNN left a message for Singleton seeking comment . Authorities have accused Hernandez , 23 , of orchestrating the death of Lloyd , the 27-year-old boyfriend of Hernandez 's fiancÃ©e 's sister . Wallace was charged with accessory after the fact to murder and has pleaded not guilty . Ortiz has pleaded not guilty to a weapons charge . Lloyd 's body was found in an industrial park near Hernandez 's home on June 17 . The police believe Lloyd was shot execution style with a Glock .45 . The weapon has not yet been found . CNN 's Susan Candiotti , George Lerner , Greg Botelho and Jason Hanna contributed to this report .
