FALL RIVER, Mass. (AP) — A nightclub manager has taken the stand in the murder trial of former New England Patriots player Aaron Hernandez as prosecutors work to establish what happened two nights before the killing.

Hernandez and Odin Lloyd were at Rumor nightclub in Boston together two nights before Lloyd ended up dead June 17, 2013.

Prosecutors have previously said Hernandez got angry with Lloyd that night, but there has so far been no testimony about what happened. A valet at a nearby hotel has testified that he saw Hernandez with a gun tucked into his waistband that night.

Manager Zeid Nabulsi is responsible for the club's video system. In his testimony Friday, he pointed out the locations of surveillance cameras in the club.

Lloyd was dating the sister of Hernandez's fiancee.
