Ex-NFL star Aaron Hernandez's fiancée took the stand in his murder trial on Friday as a key witness who was granted immunity after charges she initially lied to a grand jury investigating the case. Shayanna Jenkins, 25, was seen entering the Fall River court in Massachusetts on Friday accompanied by her lawyer and wearing her large diamond engagement ring. She told the jury that Hernandez was intoxicated and had smoked marijuana in the hours before the slaying of her sister's boyfriend, Odin Lloyd. Jenkins said she watched her partner leave their home with alleged accomplices, Carlos Ortiz and Ernest Wallace, on the night of the June 2013 murder. Jenkins also told jurors that she found a handgun in a kitchen 'junk' drawer before the June 17 murder of Lloyd, who was also her sister Shaneah's boyfriend. When she woke the following morning, her fiancée was not in their bedroom and she did not see him for several hours - but when she did, Hernandez was acting 'normal'. Scroll down for video .

There had been a question about whether prosecutors would call Jenkins, who has been in a relationship with Hernandez, 25, since high school and is the mother of his two-year-old daughter. On Friday morning, she told the judge and lawyers during a session without the jury present that she had spoken with Hernandez after she found out about the murder of semiprofessional football player Lloyd.

On Friday, Jenkins testified that she had found a black gun in the house in North Attleboro where she had moved with Hernandez and their daughter in late 2012. 'I found it in my junk drawer,' she told Assistant District Attorney William McCauley. 'I don't really remember the size.' When she found it, she found Aaron and gave him a 'stern look' - but didn't remember having any conversation about the firearm. Later, the gun was gone. It was the only gun she had seen at her home, she said. Miss Jenkins was then asked if the gun she had seen in the junk drawer was the same as Hernandez was allegedly seen on surveillance camera holding by his basement door. Jenkins told the court that she couldn't be sure if her fiancée was holding a gun, as it looked like a 'black blob'. Assistant District Attorney William McCauley held up a Glock in the courtroom, and Jenkins said it was similar in color and shape, but she was unsure how it compared in size. Jenkins furrowed her brow when the weapon was brought close to her and asked if the gun had been secured. Prosecutors earlier accused Jenkins of lying to a grand jury 29 times as it probed Lloyd's murder, including falsely saying she did not know where she had disposed of a box Hernandez asked her to get rid of after the killing. She pleaded not guilty to the charges, but acknowledged on Friday she had taken steps to conceal the box. On Friday, chief prosecutor McCauley tried to have her reveal her actions based on a cryptic text message that Hernandez sent her about an electronics box, which contained home surveillance tapes, in their basement. Jenkins claimed not have understood his message. Prosecutors say she lied to a grand jury investigating the June 17, 2013, killing of Odin Lloyd, 27, who was dating her younger sister, Shaneah. Lloyd was found shot to death at an industrial park less than a mile from the home that Jenkins and Hernandez share. The sisters introduced Lloyd and Hernandez in 2012, during a game at Gillette Stadium.
